History

Founding and Origins of the Teutonic Order

The Teutonic Order did not emerge fully formed. It was, like most of the great institutions of medieval Christendom, the product of a specific historical moment — the closing phase of the Third Crusade — and of the particular conjunction of personnel, patronage, and opportunity that the Latin East of 1190 made possible. To understand the Order is to understand the port of Acre as it stood in the autumn of that year: a crowded, feverish, politically fractured city on the edge of survival, in which German-speaking pilgrims, merchants, and crusaders found themselves with neither the protection of their own secular princes nor the institutional weight of the older military orders, and improvised, in consequence, a fraternity of their own.

Acre in 1190: The Crucible of the Order

The city into which the German fraternity was born had become, by 1190, the de facto capital of what remained of the Latin Kingdom of Jerusalem. The Holy City itself had fallen to Saladin’s forces in October 1187, after the catastrophe of Hattin, and the rump of the crusader states had been concentrated along a narrow coastal strip. Acre, the largest of these ports, was under siege by King Guy of Jerusalem; it was also, from the summer of 1189, the rallying point for the great European crusading host that the preaching of the Third Crusade had put in motion.

The German contingent of the Third Crusade arrived in separate, staggered fleets. Duke Frederick VI of Swabia reached Acre in October 1189 with the imperial vanguard; he died, however, of illness within months, and the German host was thereafter deprived of its highest-ranking lay leader. A second wave arrived in the spring of 1190. The army of the English king, Richard I — the famous Cœur de Lion — arrived in June 1191, followed shortly by the French under Philip II Augustus. The German crusaders, already in the field, found themselves politically subordinate to these later and better-led armies, and militarily marginal to the long siege that was being conducted against the city.

The conditions inside the crusader camp outside Acre were miserable. Disease was endemic; the mortality among the rank and file was appalling. The German contingent, had no permanent hospital of its own. The two established military orders, the Knights Hospitaller and the Knights Templar, maintained hospitals in the Holy City and at several Levantine ports, but their institutional capacity was strained by the demands of the siege, and the German crusaders were effectively second-class patients older orders. The improvisations of 1190 must be read against this background.

The Hospital Brotherhood of St Mary of the Germans

The conventional date of the Order’s foundation is 19 November 1190. On or about that day, a group of German merchants from the maritime cities of Bremen and Lübeck — augmented by surviving members of the German crusading host and a number of locally recruited lay brothers — joined to form a Brüderschaft, a religious fraternity, dedicated to the care of sick and wounded German pilgrims and crusaders in the camp at Acre. The fraternity was placed under the patronage of the Virgin Mary and given the title Brüderschaft des Hospitals Sankt Marien der Deutschen zu Jerusalem — the Brotherhood of the Hospital of Saint Mary of the Germans in Jerusalem. The instrument by which it was constituted has not survived in its original form, but it was confirmed, within a year, by the papal legate.

The fraternity took over a field hospital near the German sector of the crusader camp and began to receive donations of land, money, and grain from German donors in the East. The hospital was, in its early months, a tiny affair, dependent on charity and on the good offices of the German secular clergy in Acre. It had no sovereign territory, no fortified commanderies, and no standing military force. Its leadership was entrusted to a Meister, a master, elected by the brethren from among their own number.

The fraternity adopted a habit that has remained the most recognisable symbol of the Order to the present day. The brethren wore a white mantle — modelled on the Cistercian and Augustinian customs of contemporary monasticism — over which a black cross was displayed on the left shoulder. The symbolism of the cross — black upon white, recalling, it has sometimes been suggested, the supposed colours of the arms of the imperial house of Hohenstaufen — is itself an indication of the Order’s early dependence on imperial patronage.

The Early Grand Masters

The first four grand masters of the Teutonic Order presided over its transformation from a small Levantine fraternity into a militarised monastic institution. None of them, with the exception of the fourth, was a figure of European importance; the Order itself was still a minor actor on the wider stage of the crusading movement. The first three grand masters laid the institutional foundations on which the fourth — Hermann von Salza — was to build.

Heinrich Walpot von Bassenheim (in office 1190–1200) was the Order’s first grand master. A ministerialis of the Rhenish countryside, he had joined the Third Crusade in 1189 and was one of the lay founders of the fraternity. His mastership was a period of consolidation rather than expansion: he secured the Order’s first possessions within Acre, established the basic liturgical customs, and obtained from Pope Celestine III, on 19 February 1198, the bull that converted the fraternity from a hospital brotherhood into a militaris religio — a knighthood bound by religious vows, with the right to bear arms in defence of Christendom. The bull of 1198 is the document on which the Order’s later claim to the status of a full military order rests.

Otto von Kerpen (in office 1200–1208) was a knight from the lower Rhineland. His mastership saw the Order’s first tentative moves into the field of Levantine warfare, principally in support of the established orders. The Order was still too small to mount independent operations of any consequence. It received, however, a number of castles and properties in the Latin East during Otto’s tenure, and the constitutional practice of holding periodic chapters of the brethren was established in this period.

Heinrich Bart (in office 1208–1209) presided for less than a year before his death in the field. The brevity of his mastership and the obscurity of the surviving sources make him a transitional figure between the Order’s Levantine apprenticeship and the much more consequential grand mastership that followed.

Hermann von Salza and the Transformation of the Order

The election of Hermann von Salza in 1209 transformed the Order from a Levantine brotherhood of secondary importance into an institution of European consequence. Hermann was a Thuringian ministerialis — a noble of service, not of inherited blood, the typical product of the German ministerial class that staffed the chancelleries and households of the high medieval Empire. He had taken the cross at an early age, had visited the Holy Land, and was already, at his election, an experienced man in the prime of life, with the diplomatic and administrative skills that the Order most needed.

Hermann’s three decades at the head of the Order, from 1209 to his death in 1239, were decisive. He was, in turn, the trusted councillor of the Emperor Frederick II, the diplomatic intermediary between the Empire and the papacy, the chief organiser of the Order’s campaigns in the Baltic, and the architect of the Order’s constitutional structure. He negotiated the transfer of the Order’s headquarters from Acre to Venice in the late 1220s. He obtained from Frederick II the imperialis immedietas, the status of direct imperial immediacy, which exempted the Order from the jurisdiction of local German bishops and gave it freedom of diplomatic action. He extracted from the papacy the privileges that allowed the Order to hold conquered territory in perpetual tenure. He built the framework of the Order’s later European state, even though he himself never set foot in Prussia.

It is sometimes said that Hermann von Salza did for the Teutonic Order what Bernard of Clairvaux had done for the Templars a century earlier. The comparison is fair. Hermann was not a contemplative; he was a man of affairs, with an instinct for the possible and a willingness to use the great institutions of his age — the Empire, the papacy, the Latin Kingdom of Jerusalem — to advance the Order’s corporate interest. He died in 1239 in Italy, in the course of yet another diplomatic mission, and was succeeded briefly by a kinsman, Konrad von Thüringen, who completed the work of relocating the Order’s principal seat to the Baltic.

From Hospital Brotherhood to Crusading Army

The cumulative effect of the four decades from 1190 to 1230 was to convert the hospital brotherhood of Acre into a sovereign monastic corporation. The transformation was not, in any meaningful sense, planned. It was the product of two unrelated crises — the slow crisis of the Latin Kingdom of Jerusalem, and the rapid opening of the Prussian mission — and of the Order’s capacity, under Hermann’s leadership, to adapt its institutional form to the new opportunities.

In the Latin East, the Order fought alongside the established military orders and the rump of the Latin Kingdom. It distinguished itself at the battle of Damietta and in the defence of the fortresses of the Galilee. It accumulated, by 1220, a small but strategically useful set of Levantine properties that would persist for the next seventy years. In the German east, the Order was already being drawn into the Prussian mission. Duke Conrad of Masovia, a Piast prince of the Polish duchies on the middle Vistula, had appealed to the Order in 1226 for assistance against the pagan Prussian tribes. The Golden Bull of Rimini, issued by Frederick II in that same year, transferred to the Order the ius conquerendi — the right to conquer, to Christianise, and to hold in perpetual tenure — over the Prussian lands. The Order’s response was to detach a small contingent of knight-brothers to the Prussian theatre, where they were, over the next seventy years, to build the territorial state on which the rest of the Order’s history depends.

The Order and the Imperial Patronage

The political genius of Hermann von Salza lay in the relationship that he built with the imperial house of Hohenstaufen. The Empire under Frederick II was, in the early thirteenth century, the most powerful secular state in Latin Christendom. The Order, by entering into a close relationship of service to the imperial house, secured for itself the diplomatic protection of the most powerful lay sovereign in Europe, and a charter of corporate independence that no other military order could match. The price of the imperial patronage was service: the Order was repeatedly drawn into the imperial diplomacy of the German east, into the disputes of the Polish duchies, the succession crises of the Hungarian crown, and the long confrontation between the Empire and the papacy. The Order’s behaviour in these contexts has sometimes been criticised, both by contemporary and by later historians, as too closely aligned with the imperial interest. It is fairer to observe that the Order was, in the thirteenth century, a small and fragile institution, dependent on the goodwill of great powers, and that the imperial protection was, on balance, a reasonable price to pay for the corporate survival that it purchased.

The Habit, the Cross, and the Identity of the Brethren

The white mantle with the black cross, adopted in the first year of the Order’s existence, became the outward sign of a new and distinct corporate identity. The black cross on the white field — the Schwarzes Kreuz auf weißem Mantel — is one of the most durable emblems in the heraldic vocabulary of medieval Europe. It has been borne on the shoulders of knight-brothers in the Holy Land and in the Baltic, and incised on the keystones of the Order’s convent castles from Marienburg to the Syrian marches. The cross has been adopted, in modified form, by the modern German federal armed forces and by the modern Teutonic Order, and it remains, in the twenty-first century, an instantly recognisable symbol of the medieval institution from which both ultimately descend.

The internal hierarchy of the Order was also established in this period. The knight-brothers — men of free or noble birth, bound by the three monastic vows of poverty, chastity, and obedience — constituted the first estate. The priest-brothers — ordained clerics charged with the spiritual care of the Order — constituted the second. The lay brothers — the Graue Mäntel, or “grey mantles,” so called from the colour of their working habit — were charged with the manual labour of the Order’s hospitals, commanderies, and agricultural estates. The three estates corresponded, in their social origins and in the dignity of their habit, to the three-fold division of medieval religious life into the chivalric, the clerical, and the manual.

The Legacy of the Founding Period

The Order that emerged from the founding period of 1190 to 1239 was a quite different institution from the small hospital brotherhood of Acre. It had acquired a constitutional structure of considerable sophistication. It had secured, by papal and imperial grant, a set of corporate privileges that made it a sovereign body within Christendom. It had acquired a territorial base in the Latin East and was in the process of acquiring a much larger one in the Baltic. It had developed a diplomatic style and a chancery practice that compared favourably with those of the great secular states of its day. The Order’s subsequent history — the Prussian Crusade, the consolidation of the monastic state, the slow fifteenth-century decline, the secularisation of 1525 — is the working out of the institutional foundations laid in the founding period.
