These wars targeted territories that now comprise Estonia, Finland, Latvia, Lithuania, Poland, and Russia.[1] Catholic kingdoms and military orders launched military campaigns aimed at converting pagan peoples—such as Balts, Finns, and West Slavs—living around the Baltic Sea.[2] Forced baptisms and military occupation were inflicted on the native pagan populations.[1]

Life and work
Pope Celestine III's call in 1195 is the official starting point for the Northern Crusades, though Catholic kingdoms had begun subjugating pagan neighbors earlier.[3] The Danes made at least three crusades to Finland, with the first mention from 1187 mentioning a major victory over the Finns.[4] The German crusaders enlisted newly baptized Livonian warriors to fight against Latgallians, Selonians, Estonians, Semigallians, Samogitians, and Curonians.[5] The Danish fleet under King Valdemar II landed at the Estonian town of Lindanisse in 1219.[6]

The Teutonic Order, which began as a hospital around 1190 and became a military order in 1198, led many of these invasions and gained substantial wealth.[1] Pope Alexander III's 1171 crusade bull, Non parum animus noster, gave authorization for the war against the Estonians.[7]
