The Union of Lublin – Creation of Polish-Lithuanian Commonwealth

“The Union of Lublin, or creation of Polish-Lithuanian Commonwealth in the Lublin Sejm in 1569.”


The Union of Lublin, signed on July 1, 1569, was a historic event that brought together the Kingdom of Poland and the Grand Duchy of Lithuania, creating the Polish-Lithuanian Commonwealth. This union marked a significant milestone in the history of both nations, shaping their political, cultural, and social landscapes for centuries to come.


Before the Union of Lublin, Poland and Lithuania had been in a personal union since the Union of Krewo in 1386. However, they remained separate entities with their own laws, administrations, and armies. The Union of Lublin aimed to strengthen the bond between the two nations and create a unified state capable of withstanding external threats.

The Lublin Sejm

The Lublin Sejm, a parliamentary session held in the city of Lublin, Poland, was the venue for the negotiations and discussions that led to the Union of Lublin. Representatives from both Poland and Lithuania gathered to debate the terms of the union and reach a consensus.

Negotiations and Compromises

The negotiations during the Lublin Sejm were complex and required compromises from both sides. The Polish nobility, known as the szlachta, sought to maintain their privileges and influence within the new state. On the other hand, the Lithuanian nobility wanted to preserve their autonomy and protect their interests.

After months of deliberations, a compromise was reached. The Union of Lublin established a federal state, where Poland and Lithuania retained their separate legal systems, currencies, and armies. However, they shared a common monarch, parliament, and foreign policy.
