Gniezno Doors, More extensive mention of the Old Prussians in historical sources is in connection with
Adalbert of Prague, who was sent by
Bolesław I of Poland. Adalbert was slain in 997 during a missionary effort to
Christianise the Prussians. As soon as the first Polish dukes had been established with
Mieszko I in 966, they undertook a number of conquests and crusades not only against Prussians and the closely related
Sudovians, but against the
Pomeranians and
Wends as well. Beginning in 1147, the Polish duke
Bolesław IV the Curly (securing the help of
Ruthenian troops) tried to subdue Prussia, supposedly as punishment for the close cooperation of Prussians with
Władysław II the Exile. The only source is unclear about the results of his attempts, vaguely only mentioning that the Prussians were defeated. Whatever the results were, in 1157, some Prussian troops supported the Polish army in their fight against Emperor
Frederick Barbarossa. In 1166, two Polish dukes, Bolesław IV and his younger brother
Henry, came into Prussia again over the Ossa River. The prepared Prussians led the Polish army, under the leadership of Henry, into an area of marshy morass. Whoever did not drown was felled by an arrow or by throwing clubs, and nearly all Polish troops perished. From 1191 to 1193,
Casimir II the Just invaded Prussia, this time along the river Drewenz (
Drwęca). He forced some of the Prussian tribes to pay tribute and then withdrew. Several attacks by
Konrad of Masovia in the early 13th century were also successfully repelled by the Prussians.
Crusade and conquest In 1209,
Pope Innocent III commissioned the
Cistercian monk
Christian of Oliva with the conversion of the pagan Prussians. In 1215, Christian was installed as the first bishop of Prussia. The Duchy of Masovia, and especially the region of
Culmerland, became the object of constant Prussian counter-raids. In response,
Konrad I of Masovia called on the
Pope for aid several times, and founded a military order (the
Order of Dobrzyń) before calling on the
Teutonic Order. The results were edicts calling for
Northern Crusades against the Prussians. In 1224, Emperor
Frederick II proclaimed that he himself and the
Empire took the population of Prussia and the neighboring provinces under their direct protection; the inhabitants were declared to be
Reichsfreie, to be subordinated directly to the Church and the Empire only, and exempted from service to and the jurisdiction of other dukes. The
Teutonic Order, officially subject directly to the Popes, but also under the control of the empire, took control of much of the Baltic, establishing their own
monastic state in Prussia. In 1230, following the
Golden Bull of Rimini, Grand Master
Hermann von Salza and Duke
Konrad I of Masovia launched the
Prussian Crusade, a joint invasion of Prussia to Christianise the Baltic Old Prussians. The Order then created the independent Monastic State of the Teutonic Knights in the conquered territory and subsequently conquered Courland, Livonia, and Estonia. The Dukes of Poland accused the Order of holding lands illegally. During an attack on Prussia in 1233, over 21,000 crusaders took part, of which the burggrave of Magdeburg brought 5,000 warriors, Duke Henry of
Silesia 3,000, Duke Konrad of Masovia 4,000, Duke Casimir of Kuyavia 2,000, Duke Wladyslaw of Greater Poland 2,200 and the Dukes of Pomerania 5,000 warriors. The main battle took place at the
Sirgune River and the Prussians suffered a decisive defeat. The Prussians took the Christian bishop and imprisoned him for several years.
Teutonic rule Numerous knights from throughout Catholic Europe joined in the
Prussian Crusades, which lasted sixty years. Many of the native Prussians from Sudovia who survived were resettled in
Samland; Sudauer Winkel was named after them.
Frequent revolts, including a major rebellion in 1286, were defeated by the Teutonic Knights. In 1283, according to the chronicler of the Teutonic Knights, Peter of Dusburg, the conquest of the Prussians ended and the war with the Lithuanians began. In 1243, papal legate
William of Modena divided Prussia into four
bishoprics –
Culm,
Pomesania,
Ermland, and
Samland – under the
Bishopric of Riga. Prussians were
baptised at the
Archbishopric of Magdeburg, while
Germans and
Dutch settlers colonized the lands of the native Prussians;
Poles and
Lithuanians also settled in southern and eastern Prussia, respectively. Significant pockets of Old Prussians were left in a matrix of Germans throughout Prussia and in what is now the
Kaliningrad Oblast.
Conversion and language The monks and scholars of the Teutonic Order took an interest in the language spoken by the Prussians and tried to record it. In addition, missionaries needed to communicate with the Prussians in order to convert them. Records of the Old Prussian language therefore survive; along with little-known
Galindian and better-known
Sudovian, these records are all that remain of the West Baltic language group. As might be expected, it is a very archaic Baltic language.
Reformation and decline Old Prussians resisted the Teutonic Knights and received help from the
Grand Duchy of Lithuania during the 13th century in their quest to free themselves of the military order. In 1525, Grand Master
Albert of Brandenburg-Ansbach secularized the Order's Prussian territories into the Protestant
Duchy of Prussia, a vassal of the crown of Poland. During the
Reformation,
Lutheranism spread throughout the territories, officially in the Duchy of Prussia and unofficially in the Polish province of
Royal Prussia, while Catholicism survived in the
Prince-Bishopric of Warmia, the territory of secular rule comprising a third of the then
Diocese of Warmia. With Protestantism came the use of the
vernacular in church services instead of
Latin, so Albert had the
Catechisms translated into Old Prussian. Because of the conquest of the Old Prussians by Germans, the Old Prussian language probably became extinct at the beginning of the 18th century, with the
devastation of the rural population by plagues and the assimilation of the nobility and the larger population with Germans or Lithuanians. However, translations of the Bible, Old Prussian poems, and some other texts survived and have enabled scholars to reconstruct the language. ==Notes==
