Adviser for Oriental Languages and Muhammadan Law

April 1889, Batavia

The ship entered the harbour of Batavia in the early morning of April 1889, and Christiaan Snouck Hurgronje stood on deck, gazing at the coastline that was the destination of everything he had built. He was thirty-two years old. Behind him lay the Leiden dissertation, the congress journeys, the Jeddah mission, the infiltration of Mecca as Abdul Ghaffar, and the two weighty volumes of Mekka that had redrawn European Arabic studies. Before him lay a city he did not yet know and an office that no one had held before him. Batavia lay in the morning mist, low and broad, the church towers rising above the greenery, the smell of salt and rotting timber drifting from the harbour, the languid clang of ships’ bells. He would remain here for more than sixteen years.

The appointment that had brought him here bore a name that concealed its extraordinary nature in bureaucratic language: Adviser for Native and Arabic Languages and for Muhammadan Law to the Governor-General of the Dutch East Indies. No comparable office existed in the colonial administration. Snouck had not found it and applied for it; in a sense he had created it, or at least argued convincingly that it ought to be created, until the Ministry of Colonies in The Hague approved its establishment. The office had been shaped to fit the man, not the man to fit the office.

The previous article closed with his final Leiden years, with the private lectureship and the conversations with the Ministry. Here something essentially different begins. In Leiden, Snouck had produced knowledge and given instruction. In Batavia, he would convert that knowledge into policy. The distance between the library and the administrative office, which in the academic world was large and in the colonial world small, he would bridge daily. And in that transition lies the moral weight of his years in the Indies.

The lobbying campaign from Leiden, 1885–1888

Snouck’s arrival in Batavia was neither an accident nor an impulse. He had steered towards it systematically, not with the impatience of the careerist but with the slow persistence of a man who knows that the goal is attainable if one pursues it patiently. The period between his return journey from Mecca in 1885 and his departure for Batavia in 1889 was a four-year campaign, fought out on the desks of the Ministry of Colonies, in the salons of the Leiden professors, and in correspondence with people who held influence.

The Aceh War was his principal argument. That war was already raging in its second decade. The Dutch troops had quickly achieved the formal military victory, in 1873 and 1874, but the actual subjugation of Aceh proved to be quite another matter. The Acehnese population, mobilised by its religious leaders, its ulama, its teungkus, sustained a guerrilla war that cost the Netherlands hundreds of thousands of guilders a year and claimed human lives anew each year. The colonial administration did not properly understand why the Acehnese resistance was so tenacious, what its sources were, how it operated, and how it could be broken.

Snouck knew the answer, or believed he did. In Mecca he had seen the networks of the Indonesian Muslim community from within. He had spoken with the sheikhs, met the ulama ﵃, and observed the organisational structures of Islamic mobilisation. He could tell the colonial administration what it needed to know. But for that he had to be on the spot, in the archipelago itself, and not in Leiden.

In the years from 1885 to 1888 he wrote reports, memorials, and letters: to the Ministry through De Goeje and other academic patrons, and directly to the Minister of Colonies. His argument was consistent, that the Aceh War was a religious-political conflict which could only be understood and resolved by someone who knew Islamic society from within, that this knowledge was lacking in the colonial administration, that only the science of Islam, applied in the field, could supply it, that he, Snouck, possessed that science, and so they should send him to Batavia.

The Ministry hesitated. The bureaucratic obstacles were real: no budget for such an office, no precedent, no organisational position. The Ministry of Colonies was not a department accustomed to employing Islamic scholars. The officials who had to decide on the objections did not properly understand what Snouck would do or how his knowledge would improve concrete policy outcomes.

Snouck answered every objection. He produced more reports, more precise, more practical, more directed at the immediate needs of policy. He described what he would do once he was there: gather intelligence on the Islamic networks, monitor the returning pilgrims, give advice on the Acehnese situation, and support the local administration in its dealings with Islamic institutions. He made his knowledge usable in administrative terms, translating the academic analysis into policy-relevant conclusions.

It worked. Step by step, over four years, the Ministry softened its objections. The position was created, the budget found, the job description written. In 1889, with the publication of Mekka II only just behind him, Snouck accepted the appointment. He had not waited for it; he had earned it in the literal sense of the word, having earned the office for himself by demonstrating that he was indispensable.

Arrival in a city of dividing lines

Batavia in 1889 was a city of sharp dividing lines. The European quarter, with its mansions, its clubs, its churches and its offices, lay by the bay; the native quarter, the kampungs, lay behind it. Between them the Chinese lived in their own district, the Arabs in their trading quarter, the Mardijkers and the other mixed communities in their own fragments of the colony. Each group had its own legal status, its own social space, its own relationship to the colonial administration. It was not a society but a mosaic, and the cement was Dutch power.

The Islamic population was not one group but many. On Java there were the Javanese Muslims, segmented by language group, social class, and degree of Islamic practice in the familiar distinction between the santri, the pious core Muslims, and the abangan, the syncretistically inclined masses. In the outer regions there were the Acehnese Muslims, the Minangkabau Muslims, the Bugis, and the Bimanese, each with their own Islamic traditions and their own relationship to colonial authority. The Arab community, the hadramis of Yemeni origin, formed its own network of trading connections and religious authority.

Snouck had to map and understand all of this. Not from behind a desk, but on the spot, in conversations, in observations, in the analysis of documents and intelligence. His work was twofold from the very beginning, academic and operational at once. He gathered knowledge for its own value and for the policy value it held. In his person the two tasks were scarcely separable, and this indistinguishability was not a psychological peculiarity but the very core of his office.

His first weeks in Batavia he spent making contacts, familiarising himself with the administrative apparatus, and positioning his own role. The colonial administration was an extensive and hierarchical apparatus, with its own cultures, its own power structures, its own rivalries. The Governor-General stood at its head, but the actual power was distributed across the departments, the residents, the assistant residents, and the military commanders. Snouck had to find his way within this system, make his advice heard, and establish his authority.

He did so by the only route open to him, the delivery of advice that was visibly better than anything the colonial administration could produce without him. His first reports, on the Islamic community of Batavia, on the Arab networks, and on the situation in Aceh as he had observed it from Mecca, were read with attention. They combined academic depth with policy relevance in a way that the colonial officials had not encountered and greatly valued.

Buitenzorg and the workplace of power

Snouck’s actual workplace was not Batavia but Buitenzorg, now Bogor, fifty kilometres south of the capital. Buitenzorg was the seat of the Governor-General, the political heart of the colony. In the cool mountain climate, more agreeable than the coast at Batavia, the palace of the Governor-General stood amid the famous botanical gardens. Here the decisions were taken, the reports written, and the telegrams sent to The Hague.

Snouck’s office in Buitenzorg was the place where colonial Islam policy was constructed. Literally: he sat at his desk, wrote his advice, formulated his recommendations, and processed the intelligence that reached him from across the archipelago. The Governor-General, and over the years the individuals changed, consulted him on questions concerning the Islamic community. The residents sent up their questions. The military commanders asked for analysis of the Acehnese resistance. Snouck answered everything.

The institutional form of his influence was the advisory opinion. No commands, no executive power, no troops or police of his own. Yet the advice of the Adviser for Islamic Affairs carried a weight that exceeded his formal position in the bureaucratic hierarchy. Snouck was the expert, the only expert the colonial administration had. His knowledge could not be checked by others; there was no one else who read Arabic, who knew the Hajj from within, who had mastered the tradition of Islamic scholarship. His advisory opinions were authoritative pronouncements about a domain that he alone understood.

This monopoly on expertise is a form of power that is vulnerable to abuse, not through bad faith, but through the structural impossibility of correction. If Snouck said that the ulama ﵃ formed the core of the Acehnese resistance and that they had to be broken, there was no one in the colonial administration who could contradict him on solid grounds. The Governor-General had to trust the judgement of his adviser. That trust was not mutually verifiable.

The office he created

The official title of Snouck’s position suggests a limited, specialist role: adviser for languages and law. The reality was broader and more political. From his very first months in Batavia, Snouck understood his office not as that of a linguistic consultant but as that of the architect of colonial Islam policy. He was not the one who translated what others decided; he was the one who constructed the framework within which others decided.

This framework had a name that became famous in the policy history of the colony: the Islam policy. The doctrine that distinguishes between the religious and the political sphere of Islam, that tolerates the first and suppresses the second, that positions the colonial administration as the protector of the Islamic religion while it eliminates the Islamic political claims: this was Snouck’s central contribution to colonial thought.

He had already formulated it in Leiden, in the lecture hall of 1887. But in Batavia it acquired the institutional form and the policy consequences that determined its real weight. In Leiden it was an academic thesis. In Batavia it became government policy, carried out by troops, residents and courts, across an archipelago of more than three thousand islands.

The man who stepped off the boat in April 1889 perhaps did not know all of this fully. He knew that he wished to contribute, that he wished to deploy his knowledge, that he wished to make the colonial administration better in its dealings with Islamic society. But the scale of the institutional architecture he would construct, the duration of the influence he would exercise, and the moral price the Islamic community would pay for that influence: these he could not yet know in April 1889.

Or had he known it already, and was it a matter of indifference to him?

The network that preceded him

Snouck did not arrive in Batavia as an unknown. His reputation had gone before him, not only through his publications but through the networks of the colonial elite. The Governor-General and his staff knew who he was. The residents in the most important regions had heard his name. The military commanders in Aceh, who had for years struggled with a war they did not understand, knew that an expert on Islam was on his way who might perhaps be able to help them.

This network of expectations gave Snouck a standing on arrival that most colonial officials built up only after years of service. He was the expert for whom a need had been created, for whom an office had been written, for whom the system lay ready. That confers power and at the same time responsibility: whoever is so expected must deliver, and whoever promises delivery in the field of Islamic policy in the largest Muslim colony in the world delivers results that determine human lives.

Snouck delivered. In that delivering lies his intellectual greatness and his moral complication.

The correspondence with Goldziher from Batavia

Almost immediately after his arrival Snouck resumed his intensive correspondence with Ignaz Goldziher in Budapest. The letters he wrote from Buitenzorg and later from Batavia are different in tone from those of his Leiden period. They are more practical, more urgent, fed by the direct confrontation with the administrative problem he had analysed in the abstract but now had concretely before him.

Goldziher, working in his Hungarian study on the Islamic juridical and theological traditions, received reports from a world he knew only from texts. The tension between the academic science of Islam and the colonial reality that Snouck described was for Goldziher an intellectual and moral question. He had his own Islamic networks, his own admiration for the Islamic tradition, his own ambivalence about the role that European scholarship played in the colonial context.

But Goldziher was in Budapest. Snouck was in Batavia. And that geographical distance mirrors a moral distance: Goldziher was the observer, Snouck the actor. The questions they shared as intellectuals had for Snouck immediate policy consequences that for Goldziher could remain theoretical. The correspondence between the two men, which continued until shortly before Snouck’s death in 1936, is thereby a fascinating source for the internal tension of Orientalism: the scholarly project and the colonial project in the letters of men who were both engaged in the first and, to differing degrees, in the second.

The Islamic community that received him

The Islamic community of Java and the outer regions had no formal role in the arrival of the new adviser. The Governor-General was not consulted about the judgement of the ulama. The santri community of Batavia was not asked whether it desired a colonial expert on Islam. The returning hajjis, who were with increasing regularity monitored on their return from Mecca, did not know that the man who had argued for their monitoring was now physically present in their land.

The asymmetry is essential. Snouck knew the Islamic community, or believed he knew it, better than any other European. He had learned Arabic, visited Mecca, and studied the theological traditions. But his knowledge was that of the researcher, not that of the believer; that of the analyst, not that of the participant. And the Islamic community was, for him, the object of knowledge and policy, not the subject of its own political fate.

This is the fundamental tension of Snouck’s career in the Indies. He believed sincerely that he was building a bridge between the colonial administration and the Islamic community. He believed that his knowledge would make the colonial engagement with Islam more humane, more just, and more effective than the brute ignorance that had preceded him. And in some concrete cases he was right: his recommendations led to a less repressive policy towards religious practice, to protection of the pilgrimage, and to recognition of Islamic private law in the domain of family law.

But the Islamic community had not asked him to build that bridge. It had not been consulted about its architecture. And the bridge was designed primarily to serve the interests of the traffic that wished to cross it: the colonial administration, with its need for stability, obedience and profitability.

In the message of the Prophet ﷺ there is no Islam that stands outside society; the salat and the zakat are one fabric. The bridge would attempt to cut through precisely that fabric.

The agenda for the coming decades

In April 1889 Snouck’s entire career in the Indies lay before him. The Islam policy with its subtle distinction between the tolerable and the deserving of suppression: still to be constructed. The surveillance of the hajjis: still to be set up. The reports on Aceh, the mission to Kotaraja, the advice on the ulama as the irreducible enemy of the colonial order: still to be written. The Short Declaration of 1899, which delivered the Acehnese elite to colonial authority as the price of protection: still to be designed. The collaboration with Van Heutsz, the military governor whose name is bound to the bloodiest phase of the Aceh War: still to begin.

All of this would grow out of the man who stood on deck in April 1889 as the ship entered the harbour of Batavia. It was not predetermined; at every point there were choices, directions that could have been otherwise. But the intellectual architecture that would feed the choices was already fully formed. Snouck already had his doctrine. He already had his method. He already had his conviction that Islamic society could be governed by understanding it better than it understood itself.

What was lacking was only the execution. And that execution began the next day, at his desk in Buitenzorg, with the first report on the first Islamic question that the colonial administration laid before him.

The first months: orientation and positioning

In the months after his arrival Snouck oriented himself carefully within the complex administrative landscape of the Dutch East Indies. He was an outsider who had to become an insider, and he did it in the manner that suited him best: by reading, observing, questioning, and writing.

He began by studying the files that the colonial apparatus had built up on the Islamic community. Those files were sometimes voluminous, always incomplete, and often fundamentally misleading in their categorisation of the Islamic dynamic. The colonial officials who had compiled them were sometimes capable observers but rarely men who knew the Islamic tradition from within. They described what they saw but did not always understand it in its own logic.

Snouck read these files with the combination of academic precision and policy urgency that characterised his work. He noted the gaps, the misinterpretations, and the categorical errors. And he began to build up his own files, his own descriptions of the Islamic social structures, the religious networks, and the connections between the local communities and the international Islamic world.

His first official reports were cautious in tone but immediately clear in their analytical position. The Islamic community of the archipelago was not one thing but many. Java was not Aceh. The Minangkabau were not the Bugis. Each region had its own religious traditions, its own relationship to the Islamic centre in Mecca, its own balance of Islamic and pre-Islamic elements in its culture and social organisation.

This plea for differentiation was not only scholarly but also practical: the colonial administration that treated the Islamic community as one homogeneous mass would make policy that turned out wrong everywhere. Only a differentiated analysis, fed by specific knowledge of the local situations, could produce policy that was effective. And that differentiated analysis Snouck could supply like no one else.

Batavia as a city of information flows

Batavia in 1889 was a city of information flows that crossed one another and sometimes worked against one another. From the seventeen regions of the Dutch East Indies came reports, requests, complaints, and intelligence. From the military posts in Aceh came dispatches about the progress of the campaign, the losses, and the movements of the Acehnese fighters. From the residencies of Java came notifications about Islamic organisations, about unrest in the kampungs, and about returning pilgrims who brought new ideas with them.

Snouck positioned himself as the filtering point for all Islamic information in this system. Every dispatch that touched upon the Islamic community, every question about Islamic law, every notification of Islamic political activity: it had to pass across his desk. He was the translator, the analyst, the man who converted the raw flow of information into intelligible categories and usable policy recommendations.

This was an enormous accumulation of power, and it took place almost as a matter of course, as a consequence of his unique expertise. For there was, after all, no one else who could do it. The Governor-General had no Arabic. The residents did not know Islamic jurisprudence. The military commanders knew little of the theological structures of Islamic resistance. Only Snouck could connect all these matters into a coherent picture.

Informational power is the first and fundamental power in an administrative system: whoever determines what counts as relevant information, who determines the categories in which the information is ordered, who supplies the interpretations that render the facts intelligible, that person determines to an important degree the policy that is made on the basis of that information. Snouck held this monopoly on Islamic information for the colonial administration of the Dutch East Indies.

Javanese society and its Islamic stratification

One of the first great analytical projects that Snouck undertook in Batavia was mapping the Islamic stratification of Javanese society. Java was the administrative heart of the colony, the most densely populated island, the source of most of the tax revenue, and the place where the tensions between the colonial administration and the Islamic community were most complex.

Javanese society had a stratified pattern of Islamic practice that the colonial administrators did not properly understand. On one side stood the santri: the pious core Muslims, the bearers of strict Islamic practice, the pupils of the pesantren, the people for whom the Islamisation of Javanese society was an active project. On the other side were the abangan: the mass of the Javanese population that experienced a syncretistic Islam, blended with pre-Islamic Javanese spiritual traditions, in which the Islamic rituals coexisted with magical practices, spirit cults, and a court culture that was more Hindu than Islamic in character.

Between the two stood the Javanese aristocracy, the priyayi, who cherished their own cultural identity, an identity that combined Javanese courtly culture with a pragmatic Islamism that accommodated the colonial order. The priyayi were the natural allies of the colonial administration: they had interests in the maintenance of the social order that confirmed them in their privileged position.

Snouck’s analysis of this stratification was nuanced and had direct policy implications. The santri, the pious Islamic core, were the potential basis of Islamic political mobilisation. They were the people who read the Arabic texts, who maintained the connection with Mecca and the international world of Islamic scholars, who regarded Islamic law as the normative framework for public life. They were also, in Snouck’s eyes, the group that had to be monitored most carefully for signs of political Islamic activity.

The abangan were, from the perspective of the Islam policy, less dangerous: their syncretistic Islam was less theologically coherent, less connected with the international Islamic juridical tradition, and less susceptible to the pan-Islamic message. But they were also less stable: their loyalty was diffuse, their social organisation weaker, and their potential for mobilisation in other directions just as real.

This was the sociological map that Snouck drew of Javanese Islamic society. It was a map that would colour colonial policy on Java for decades.

The relationship to the Interior Administration

A crucial aspect of Snouck’s position in Batavia was his relationship to the Interior Administration, the division of the colonial apparatus that was responsible for the daily governance of the population through the residents, assistant residents, and controllers who worked in the various regions. The Interior Administration was the backbone of the colonial administration, the body that had direct contact with the local population.

Snouck’s relationship to the Interior Administration was structurally complex. He was an adviser, not a line official. His recommendations carried authority but no binding force. The residents and their subordinates could set his advice aside if they wished, and sometimes they did, either out of ignorance or out of unwillingness to place the judgement of an academic above their own practical experience.

Snouck responded to this by formulating his advice in such a way that it was difficult to ignore: concrete, detailed, documented, with explicit references to the policy consequences of not following it. He built up his authority by being right, and he was right often enough that his position in the administrative system grew ever stronger. Governors-General who heard him said this almost unanimously: the man knew whereof he spoke.

But the relationship to the Interior Administration was also a relationship to the practice of colonial governance on the ground, where the rough work was done, where the rules were enforced, where the people were governed whom Snouck described in his reports. That practice was sometimes in accordance with his advice and sometimes far removed from it. The deviations were not always his fault, but sometimes they were also the consequence of his categories: whoever has classified the ulama as enemy and the uleëbalang as friend has provided a framework whose practical application by others escaped him.

The first reports on Aceh

Already in his first year in Batavia, Snouck began to write letters and memoranda on the Aceh situation. The Aceh War was at that moment nearly sixteen years old and cost the colonial administration millions of guilders and hundreds of human lives each year. The military strategy that had been tried, the so-called Van der Heijden system of defensive concentration, had not broken the Acehnese resistance. On the contrary, the resistance seemed in some areas more intense than ever.

Snouck’s early reports on Aceh were analytical and cautious in tone. They held that the nature of the Acehnese resistance was fundamentally religious and that a purely military approach could not solve the problem. The ulama ﵃ who organised and legitimised the resistance could not be overcome by military pressure alone. The Islamic religious infrastructure of Aceh, the meunasahs, the pesantren, and the networks of the religious scholars, were the bearers of the capacity for resistance.

But those early reports already contained the core of the later analysis: the distinction between the uleëbalangs and the ulama, the possibility of co-opting the first while the latter had to be broken. This distinction lay already in the earliest Batavia analyses, long before Snouck himself travelled to Aceh.

It was the analytical foundation on which his entire career in the Indies would rest.

The moment before the clock

There is a moment at which knowledge becomes power and power acquires consequences that the producer of the knowledge can no longer control. Snouck did not reach that moment on the day of his arrival, but the arrival was the threshold step. He was now inside the system, not outside it as an academic offering commentary. His advice would be converted into policy, the policy into instructions, the instructions into acts by men bearing weapons and legal authority.

The distance between the study and the battlefield had, in April 1889, become shorter than it had ever been in Snouck’s life. As the years passed, that distance would shrink further, to the point where his reports on the Acehnese ulama contributed directly to the military operations that eliminated those ulama.

That is the lesson of the arrival in Batavia: not that Snouck was a villain who entered the archipelago with evil intentions, but that the road to hell is paved with usable knowledge. The Islam policy he would construct began its life already on that deck, in April 1889, as the conviction of a scholar that knowledge leads to understanding and understanding to just governance.

The Islamic community of Indonesia would pay the price for the naivety of that conviction, and for the power that its holder had acquired for himself.

What that doctrine looked like, what it promised and what it concealed, will be unfolded in the following article. There the man already sits at his desk in Buitenzorg, with the rain on the roof and the city beyond, and formulates the separation that would outlive the centuries.

The material conditions of his existence in Batavia

Snouck’s life in Batavia and Buitenzorg was comfortable by colonial standards. He had a residence, staff, and a salary that enabled him to maintain the standard of living considered fitting for a European official of his rank. The material condition was untroubled; the intellectual condition was stimulating.

But there was also his health. The tropical climate of the Indies archipelago was hard on Europeans, and Snouck in his years in the Indies was not free of the health problems that the climate brought with it. His correspondence sometimes mentions periods of illness, of exhaustion, of the need to recover before he could resume his work.

And there was also the personal sphere. Snouck married in Indonesia, according to Islamic law, to an Indonesian woman, and later a second. This was not unusual for European men in the colony, but it also had an intellectual dimension for Snouck: it was a concrete form of his relationship to the Islamic society he studied. Whether this conduct in marriage was an expression of sincere attachment, of opportunism, or of a combination of the two: these are questions to which the historical sources give no unambiguous answer.

What the marriage did not do was change his analytical position. The man who married an Indonesian woman remained the same man who classified the Acehnese ulama ﵃ as irreducible enemies of the colonial order. The personal intimacy and the analytical detachment existed side by side, unresolved.

The technical infrastructure of the advisory office

The practical working of Snouck’s office also required a technical infrastructure: translators, copyists, informants, and correspondents in the regions who supplied him with the information on the basis of which he formulated his advice. This infrastructure was not a given; it had to be built up and maintained.

In his first Batavia years Snouck had built up a network of informants who reported to him from across the archipelago. Some were Arab traders who enjoyed his confidence. Others were Islamic scholars willing to speak with him, drawn by his command of the Arabic language and his knowledge of the Islamic traditions. Still others were colonial officials in the regions who passed his questions on to local contacts.

This network was the actual foundation of his advice. The reports he wrote were not solely the products of his own observations; they were also based on information that had come to him through this network. The reliability of that information depended on the motives of the people who supplied it, motives that Snouck could not always fully control.

In the colonial context informants were seldom neutral sources of information. They had their own interests: the trader who informed on his rivals, the uleëbalang who informed on the ulama who threatened his own position, the official who wished to keep his post by supplying his superior with information that satisfied him. All of this coloured the information that reached Snouck, and thereby coloured the advice he formulated. Colonial knowledge was never as impartial as it appeared in the reports; it was shaped by the hand that passed it on, and by the hand that desired it.

The adviser and his shadow

In the closing hour of his first month in Batavia, after the first audiences with the Governor-General, after the first tour of the departments, after the first reports he had written, Snouck had become a man with a growing shadow. Not his physical shadow, which was the same, a tall, slender figure with a high forehead and an attentive gaze. But his institutional shadow, the effect that his mere presence had on the flows of information and policy in the colony, was already visibly larger than the office he formally held.

Advisers have shadows because they stand at the edge of power without formally exercising it. Their word carries weight without being a command. Their recommendation tips the balance without their holding the pen with which the instruction is written. And they bear, for that reason, a responsibility that often escapes them in their own self-image: they were merely adviser, merely scholar, merely the voice that the Governor-General had consulted before he decided.

But the advice that is converted into policy bears the signature of the adviser, even when the signature is not visible on the final instruction. Snouck would not always acknowledge this later, in his Leiden years. But in April 1889, at his newly cleared desk, with the fan turning softly and the sound of Buitenzorg coming in through the pushed-open window, the architecture of his influence had already begun to take shape.
