[5] Baldwin convinced the Curonians to submit to the Bishopric of Riga in the winter of 1230–1231 in exchange for food aid addressing the famine in Livonia and Novgorod; due to disputes over the division and baptism of Courland, he had to flee to the monastery of Daugavgrīva (Dünamünde).
[5] He set up his base in Wiek in western Estonia, and in summer 1233 demanded that the Livonian Brothers of the Sword hand over the castle of Reval (later Tallinn).
[8] Historians argued that Baldwin attempted to make the whole Baltic region an ecclesiastical state, but Manfred Hellmann [de] (1993) rejected this idea as "fanciful speculation".
[8] Papal correspondence with Baldwin was primarily concerned with ending the conflict in Livonia on terms favourable to Rome, rather than conquering part of Pskov and Novgorod.
[10] In 1239, Baldwin accompanied Baudouin de Courtenay in the Barons' Crusade and took over the responsibilities of the archbishop of Vizia in Thrace, in the Latin Empire.
