Since when did Pope blessed crusades into Northern Europe? There was conquests going on in Baltics, Livonian order, but that was over control of land. References?
As per Wiki:
The Northern Crusades or Baltic Crusades were religious wars undertaken by Catholic Christian military orders and kingdoms, primarily against the pagan Baltic, Finnic and Western Slavic peoples around the southern and eastern shores of the Baltic Sea, and to a lesser extent also against Orthodox Christian Slavs (East Slavs). The crusades took place mostly in the 12th and 13th centuries and resulted in the subjugation and forced baptism of indigenous peoples.
The official starting point for the Northern Crusades was Pope Celestine III's call in 1195, but the Catholic kingdoms of Scandinavia, Poland and the Holy Roman Empire had begun moving to subjugate their pagan neighbors even earlier. The non-Christian people who were objects of the campaigns at various dates included:
the Polabian Wends, Sorbs, and Obotrites between the Elbe and Oder rivers (by the Saxons, Danes, and Poles, beginning with the Wendish Crusade in 1147)
the Finns proper in 1150s in controversial First Crusade by the Swedes; by the Danes in 1191 and 1202; Tavastia in 1249 in Second Crusade by the Swedes; and Karelia in 1293 in the Third Crusade by the Swedes; Christianization in these areas had started earlier,
Livonians, Latgallians, Selonians, and Estonians (by the Germans and Danes, 1193–1227),
Semigallians and Curonians (1219–1290),
Old Prussians,
Lithuanians and Samogitians (by the Germans, unsuccessfully, 1236–1316).
