Albert of Riga
Albert headed the armed forces that forcibly converted the pagan indigenous population of the eastern Baltic region to Christianity as a result of the Northern Crusades.In 1200, Bishop Albert led a crusade in Livonia, providing the starting point to create an ecclesiastical State.These rights led him to create an annual summer expedition from Lübeck to Livonia called the "perpetual crusade".[2] Together with merchants from the Baltic Sea island of Gotland, Albert founded Riga in 1201,[3] where a small community of Hanseatic traders from Lübeck held a tentative trading encampment.[1] He successfully converted many Livs under their leader Caupo, offering them protection against neighboring Lithuanian and Estonian tribes; Albert also subjugated Latvian principalities of Koknese, Jersika and Tālava later on.
