Battle of Wilkomierz - Aftermath

Aftermath

The battle reduced the power of the Livonian Order as its army was defeated, Grand Master killed, and many senior officers taken prisoners. The damage to the Livonian Order caused by the battle is often compared to the consequences that the Battle of Grunwald (1410) had on the Teutonic Knights. The peace treaty was signed on December 31, 1435 in Brześć Kujawski. The Teutonic and Livonian Orders promised not to interfere with internal matters of Lithuania or Poland. Even Pope or Holy Roman Emperor could not force the Orders to violate the treaty. The peace did not alter borders established in the Treaty of Melno (1422). Livonian Order's defeat in the battle brought it closer to its neighbors in Livonia. The Livonian Confederation agreement was signed on December 4, 1435 by the Livonian Order, Livonian Bishops, vassals and city representatives.

Švitrigaila escaped and continued to resist, but he was losing his power in the eastern provinces of the Grand Duchy of Lithuania. In 1437, he proposed a compromise: he would continue to rule Kiev and Volhynia, territories that still remained loyal to him, in exchange for peace and promise to transfer these lands after his death to the King of Poland. Because of strong protests from Sigismund Kęstutatis, the Polish Senate did not ratify the agreement. The following year Švitrigaila retreated to Moldavia. Sigismund became the undisputed Grand Duke of Lithuania. However, his reign was short as he was assassinated in 1440. A church was built in the battlefield by Sigismund Kęstutaitis to commemorate his victory. The town of Pabaiskas later grew around the church.
