OTL Teutonic Order States in Prussia and Livonia looked like this. Over time Baltic Prussians became more loyal citizens of TO state than German urban population of large towns, like Danzig or Thorn, who were more and more unhappy about rising taxes and finally rebelled against TO in 1454. Baltic Prussians were even allowed to keep their religion even as late as during 1520s (at the time of the lasts wars between Poland and Teutonic Order, in 1520 Prussian Pagan priest Waltin Supplit asked Grand Master for permission for performance of pagan rituals in Sambia, Grand Master agreed. Thousands of Prussians gathered on the Baltic coast and begged their gods to save Prussia from invasion of Danzig fleet, allied with Poland. They sacrificed black bull to the gods, and seemingly that worked, because Danzig fleet retreated. That is how Teutonic Crusader States fullfilled their mission![]()
Wow, I hadn't realized that paganism lasted so long in Prussia! Do you have any good English Language sources that cover the period; I'd love to read more!
