The Livonian Branch

The Sword Brothers (1202–1237)

The Brotherhood of the Sword — Schwertbrüderorden in German, Fratres Miliciae Christi de Livonia in Latin — was the first military order established in the eastern Baltic. It was founded in 1202 by Bishop Albert of Riga, with the support of the German merchant community of Riga, and it served, for thirty-five years, as the principal military instrument of the Latin church in Livonia. The Brotherhood fought a long series of campaigns in Livonia, Courland, and Estonia. It acquired, by the 1230s, a substantial territorial state. It was, however, a small and exposed force, and it suffered, in 1236, the catastrophic defeat at the battle of Saule that destroyed most of its senior knight-brothers and left the surviving brethren no choice but to apply for incorporation into the Teutonic Order. The merger was completed in 1237, and the Brotherhood of the Sword was, in effect, dissolved.

The Brotherhood of the Sword is, in the wider history of the Teutonic Order, an important chapter. It was the prototype of the Livonian branch. It was, for the Order, the most direct precedent for the much larger territorial state that the Order was to build, in the same period, on the south-eastern Baltic. And it was the Order’s first experience of the particular kind of military-religious activity that the conquest and defence of the eastern Baltic required.

The Founding of 1202

The Brotherhood of the Sword was founded in 1202, two years after the arrival of Bishop Albert in Livonia and one year after the establishment of the city of Riga. The circumstances of the foundation are described in the Chronicle of Henry of Livonia, the principal contemporary source for the early history of the Latin church in Livonia. Henry records that Albert, recognising that the Latin church in Livonia required a permanent military force for its defence, established a fraternitas militiae — a military brotherhood — under the patronage of the Virgin Mary. The new brotherhood was modelled on the Templars and Hospitallers, and it was given the privileges of a militaris religio — a knighthood bound by religious vows and authorised to bear arms in defence of Christendom.

The Brotherhood was, in its early years, a small and improvised body. Its first Master, Wenno von Rohne, was a German nobleman of modest background who had accompanied Albert to Livonia. Its initial complement was, by all accounts, no more than a few dozen knight-brothers, augmented by a small number of locally recruited lay brothers. The Brotherhood’s principal base was the city of Riga, where it was assigned a house and a chapel by the bishop.

The Brotherhood’s principal patrons, in its early years, were the German merchants of Lübeck and Gotland, who had been trading in the Baltic for several generations. The merchants’ interest in the Brotherhood was, in part, religious, but it was also, in part, commercial. The merchants were eager to secure the routes that led to the Russian market, and they were willing to provide material support to a military force that would protect those routes. The Brotherhood’s relationship with the merchants was, in this sense, a working partnership between two complementary interests.

The Conquest of Livonia

The Brotherhood played a decisive role in the conquest of Livonia, Courland, and Estonia in the first third of the thirteenth century. Its principal campaigns were:

The conquest of Livonia, completed in 1207 with the submission of the Livs and the Latgalians. The campaign was a slow process, conducted over several years, and the Brotherhood’s principal role was the garrisoning of the fortified posts that the bishop had established along the lower Daugava. The campaign was completed in 1207, when the Livonian chieftains acknowledged the suzerainty of the bishop and accepted baptism.

The conquest of Estonia, completed in 1227 after a long and difficult campaign against the Oeselians, the Ugandians, and the other Estonian tribes. The campaign was marked by several major reverses — the Estonian uprising of 1223 destroyed most of the Latin settlement in northern Estonia, and the Brotherhood suffered a serious defeat at the battle of Soontagana in 1220 — but it was eventually successful, and by 1227 the Estonian territories had been incorporated into the Latin church.

The conquest of Semigallia, completed in 1230. The Semigallian campaign was a difficult operation in difficult country, and the Brotherhood was unable to hold the territory against the persistent Semigallian resistance. The campaign was eventually concluded by an agreement under which the Semigallians were converted to Christianity and acknowledged the suzerainty of the Latin church.

The conquest of Courland, completed in 1267 — although this campaign was, by the time it was completed, the work of the Teutonic Order rather than the Brotherhood.

The Brotherhood was, in the conduct of these campaigns, an effective military instrument. It fought a series of successful operations against numerically superior opponents. It established a chain of stone castles that secured the Latin church’s hold on the territory. It developed, over time, a sophisticated doctrine of frontier warfare that combined mobility, concentration, and the disciplined use of the crossbow.

The Constitutional Position of the Brotherhood

The constitutional position of the Brotherhood was, from the outset, ambiguous. The Brotherhood was, in theory, an autonomous military order under papal authority. In practice, however, the Brotherhood had been established by the Bishop of Riga and acted on his behalf. The early Masters were chosen by the bishop and were dependent on his support; the principal revenue came from the bishop’s endowment and the German merchants; the principal base was the city of Riga, which the bishop controlled. The tension between papal authority and the bishop’s effective control was a constant theme of the Brotherhood’s history. The tension came to a head in 1230, when the Brotherhood attempted, with the Pope’s support, to assert its independence of the bishop. The attempt failed, and the Brotherhood was forced to acknowledge, in a series of agreements, the bishop’s continuing authority.

The Battle of Saule 1236

The Brotherhood’s effective history came to an end at the battle of Saule on 22 September 1236. The battle was fought in western Lithuania, between a force of the Brotherhood and a combined Lithuanian-Samogitian army. The Brotherhood was, by all accounts, the aggressor: the Master, Volkwin, had led a substantial force into Samogitia in an attempt to subdue the Samogitians, who had been in revolt against the Latin church since 1230.

The battle was a Lithuanian victory of the first order. The Lithuanian and Samogitian forces, although not greatly superior in numbers, were in a strong tactical position, and the Brotherhood’s force was destroyed. The Master, Volkwin, was killed, together with most of the senior knight-brothers. The order’s military capacity was effectively destroyed, and the surviving brethren were unable to defend the order’s territories.

The battle of Saule was, in the wider context of the Latin church in the eastern Baltic, a disaster. The Samogitians, encouraged by the victory, repudiated the Latin church and resumed their raids on Livonia. The Order’s territories in southern Livonia were exposed to Lithuanian attack. The Order’s principal ally in the region, the Bishop of Riga, was unable to provide the military support that the order required.

The Merger with the Teutonic Order

The surviving brethren, recognising that the Brotherhood could not continue as an independent order, applied for incorporation into the Teutonic Order. The application was supported by the Bishop of Riga and by the German merchants of Riga. It was approved by Pope Gregory IX, in the bull Omnis terrae, on 12 May 1237.

The terms of the merger were generous to the surviving brethren. The Teutonic Order accepted the surviving members of the Brotherhood as full members of the Teutonic Order, with the right to retain the principal commanderies of the Brotherhood and to be governed initially by their own officers. The Livonian branch of the Teutonic Order, as the new formation was called, was to be governed by a Master, the Landmeister of Livonia, who was to be elected by the chapter of the Livonian knight-brothren and confirmed by the Grand Master at Marienburg.

The merger was, in effect, a reconstitution of the Brotherhood under a different corporate name. The Livonian branch inherited the Brotherhood’s territorial possessions, the Brotherhood’s network of stone castles, and the Brotherhood’s administrative practices. The Livonian branch was, for the first century after the merger, governed by Masters who had been knight-brothers of the Brotherhood and who regarded the legacy of the Brotherhood as the foundation of the new order’s identity.

The Livonian branch was, from the outset, a relatively autonomous formation within the Teutonic Order. The Master of the Livonian branch was, a sovereign prince: he had his own chancery, his own treasury, his own foreign policy, and his own military establishment. The Grand Master at Marienburg, although formally the superior of the Master of the Livonian branch, was, in practice, a distant overlord whose authority was exercised only at the moment of the Master’s election and at the major moments of common policy.

The autonomy of the Livonian branch was, in part, a product of geography. The Livonian branch was separated from the Prussian state by a hundred miles of Lithuanian and Samogitian territory that the Order did not control, and communication between Riga and Marienburg was slow and difficult. The autonomy was also, in part, a product of the constitutional arrangements of the merger, which had left the Livonian branch with a substantial degree of internal self-government. The Grand Master at Marienburg, occupied with the much larger and more immediate problems of the Prussian state, was content to leave the Livonian branch to its own devices.

The Legacy of the Sword Brothers

The Brotherhood of the Sword is, in the modern historiography of the Teutonic Order, a chapter of considerable importance. It was the first military-religious order established in the eastern Baltic, the principal military instrument of the Latin church in Livonia for the first third of the thirteenth century, and the prototype of the much larger territorial state that the Teutonic Order was to build in the same period on the south-eastern Baltic.

The Brotherhood’s legacy to the Livonian branch was substantial. The Livonian branch inherited the Brotherhood’s territorial possessions, the Brotherhood’s network of stone castles, the Brotherhood’s administrative practices, and the Brotherhood’s commitment to the defence of the Latin church in the eastern Baltic. The Livonian branch was, in effect, the Brotherhood of the Sword under a different name, and the master of the Livonian branch was, in the constitutional sense, the successor of the master of the Brotherhood.

The Brotherhood’s experience of the conquest and defence of the eastern Baltic was the first substantial body of practical knowledge on which the Teutonic Order could draw in the much larger conquest of Prussia. The Brotherhood’s experience of the constitutional tensions between a military order and a territorial bishop was a precedent that the Teutonic Order would encounter, in different forms, in the Prussian and Hungarian theatres. The Brotherhood’s catastrophe at Saule in 1236 was, in the longer term, a fortunate event for the Teutonic Order: it brought into the Order the substantial territorial possessions of the Brotherhood and the considerable body of practical experience that the Brotherhood had accumulated in thirty-five years of frontier warfare.
