Order of Dobrin

The Order of Dobrzyń (Polish: Zakon Dobrzyński) or Order of Dobrin (German: Orden von Dobrin), also known as the Brothers of Dobrzyń (Polish: Bracia Dobrzyńscy), 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.

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 (German: Dobriner 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.
