Order of Dobrzyń
The Order of Dobrzyń () or Order of Dobrin (), also known as the Brothers of Dobrzyń (), was a military order created in the borderland of Masovia and Prussia (today's Dobrzyń Land, Poland) during the 13th century Prussian Crusade to defend against Baltic Prussian raids. In Latin the knights were known as being a smaller part of the much bigger and older Fratres Milites Christi (de Prussia, de Dobrin, de Dobrzyń, de Mazovia), and they were nicknamed the Prussian Cavaliers of Jesus Christ. The Order was created by Christian of Oliva, the first Bishop of Prussia (1216–1228), to protect Masovia and Kuyavia against raids from the pagan Prussians who defied Duke Konrad I of Masovia's attempts to subjugate them. According to Jan Długosz, the creation of the Order was confirmed by Pope Gregory IX (1227–1241) in 1228. Duke Konrad granted the Knights the town of Dobrzyń (Dobrin) and the surrounding Dobrzyń Land (), territory located south of and adjacent to Prussia. The Order of Dobrzyń was the only military order created in the territory of Poland. At first the Order was composed of 15 German knights from Lower Saxony and Mecklenburg led by Master Brunon. The Order of Dobrzyń provided assistance to the Cistercian missionaries in Prussia and protection from the raids of the pagan Prussian tribes. Their ideology was represented by their clothing - over their armor they had white cloaks, with symbols of a red sword raised up and a red star representing the revelations of Jesus to non Christians. The rules of their orders were based on those of the Livonian Order and the Knights Templar. In the face of the Order's lack of success in battle against the Prussians, as well as their small number (at its highest, 35 knights), in around 1235 the majority of the Knights joined the Teutonic Order, as allowed by a papal document, the Golden Bull of Rieti. In 1237 the rest of the Brothers were moved by Konrad to Drohiczyn to increase the military strength of that outpost. The Brothers of Dobrin were last mentioned when Drohiczyn was captured by Prince Daniel of Galicia in 1240. References
