Origins & Foundation

The Union of Krewo emerged from a complex succession crisis in Poland following the death of Louis I of Hungary in 1382. Poland faced uncertainty regarding the throne due to the limited number of surviving heirs. This instability created a crucial geopolitical opening that Lithuania, under Jogaila, was poised to exploit. The negotiations were centered around securing a marriage alliance that would stabilize the region for both powers.

Breakthrough & Iconic Era

The pivotal moment occurred on August 14, 1385, when Jogaila, Grand Duke of Lithuania, made prenuptial promises at Kreva Castle. These promises were made concerning his prospective marriage to the underage reigning Queen Jadwiga of Poland. This agreement, though initially limited in scope, represented a profound commitment to shared destiny. It directly paved the way for Jogaila's conversion to Christianity and his subsequent crowning as King of Poland in 1386.

Enduring Legacy & Impact

The Union of Krewo proved to be a decisive historical turning point for both Poland and Lithuania. It marked the commencement of four centuries of intertwined history between the two polities. This shared trajectory eventually culminated in the formation of the Polish–Lithuanian Commonwealth by 1569. This grand union persisted until the Third Partition of Poland in 1795, leaving an indelible mark on Eastern European history.
