Dorpat

Dorpat was a prince-bishopric in southeastern Estonia, centered on Tartu, formerly Yuryev. Its bishop Engelbert ruled in 1337, and the see belonged to the Livonian sphere.

Dorpat became a Hanseatic centre whose bishops contested the Livonian Order. Bishop Dietrich Damerow allied with Lithuania and the Victual Brothers before the Order’s failed invasion in 1379. In the sixteenth century Ivan the Terrible claimed Dorpat as Yuryev and demanded tribute, helping precipitate the Livonian War. Russian troops captured Tartu in 1558, ending the bishopric.
