Berthold of Hanover (died 24 July 1198) was a German Cistercian and Bishop of Livonia, who met his death in a crusade against the pagan Livonians.
At the death of Saint Meinhard, the first Bishop of Livonia (c. 1196), Hartwig of Uthlede, Archbishop of Bremen, to whose province belonged the newly converted countries along the eastern shores of the Baltic Sea, appointed Abbot Berthold successor.
Berthold's predecessor, assisted by merchants from Bremen and Lübeck and a few converts, had built fortifications along the River Düna, where Christians held their religious services and could protect themselves.
In a short time a large fleet was ready for departure, well equipped and loaded with crusaders and many German peasants who were to settle permanently in Livonia.
A pagan by the name of Ymaut[2] (wrongly read as Ymant)[3] thrust his lance into Berthold's back, inflicting a wound that caused speedy death.
