The Bishopric of Dorpat was a medieval prince-bishopric, i.e. both a diocese of the Roman Catholic Church and a temporal principality ruled by the bishop of the diocese. It existed from 1224 to 1558, generally encompassing the area that now comprises Tartu County, Põlva County, Võru County, and Jõgeva County in Estonia. The prince-bishopric was a sovereign member of the Holy Roman Empire and part of the Livonian Confederation until its dissolution in 1561.

Tartu is the second largest city in Estonia after Tallinn. Tartu has a population of 97,435. It is 186 kilometres southeast of Tallinn and 245 kilometres northeast of Riga, Latvia. Tartu lies on the Emajõgi river, which connects the two largest lakes in Estonia, Lake Võrtsjärv and Lake Peipus. From the 13th century until the end of the 19th century, Tartu was known in most of the world by variants of its historical name Dorpat.
