Order of Dobrzyń

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.

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.

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.
