As the Bishop of Livonia, in 1201, he founded Riga, the modern capital city of Latvia, and the city was later made a bishopric. The building of the Riga Cathedral started during his tenure there in 1221.
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.
