The treaty was signed in the aftermath of the Livonian Order's defeat at the hands of the allied Polish-Lithuanian force in the Battle of Wiłkomierz.

The Teutonic Knights agreed to cease their support to Švitrigaila (who tried to break the Polish-Lithuanian union) and in the future to support only Grand Dukes properly elected jointly by Poland and Lithuania.

[1] The Peace of Brześć Kujawski showed that Teutonic Knights lost their universal missionary status.

[2] Teutonic and Livonian Order no longer interfered with Polish–Lithuanian affairs; instead Poland and Lithuania involved themselves in the Thirteen Years' War, the civil war in Prussia that tore it in half.

[4] The treaty was announced in the Gothic Saint Stanislaus church in Brześć Kujawski.
