Years: 1236 - 1236

Twenty-one Lithuanian dukes had signed a peace treaty with Galicia–Volhynia, in 1219, an event today widely accepted as the first proof that the Baltic tribes were uniting and consolidating.

Two German religious orders, the Teutonic Knights and the Livonian Brothers of the Sword, have in the early thirteenth century conquered much of the area that is now Estonia and Latvia, in addition to parts of Lithuania.

In response, a number of small Baltic tribal groups unite under the rule of Mindaugas, who is referred to as the ruler of all Lithuania in the Livonian Rhymed Chronicle in 1236.
