The Golden Bull of Rimini was a decree issued by Emperor Frederick II in Rimini in March 1226 that granted and confirmed the privilege of territorial conquest and acquisition for the Teutonic Order in Prussia.[1] According to historian Tomasz Jasiński, the bull was backdated and had actually been issued in 1235.[2][3] It represents the first of a series of three documents, that include the Treaty of Kruschwitz of 1230 and the Papal Golden Bull of Rieti of 1234.[4][5]
