The Great Sejm of the Polish–Lithuanian Commonwealth was disbanded following the Russian invasion of Poland.

The Great Sejm, also known as the Four-Year Sejm was a Sejm (parliament) of the Polish–Lithuanian Commonwealth that was held in Warsaw between 1788 and 1792. Its principal aim became to restore sovereignty to, and reform, the Commonwealth politically and economically.

The Polish–Lithuanian Commonwealth, also referred to as Poland–Lithuania or the First Polish Republic, was a federative real union between the Kingdom of Poland and the Grand Duchy of Lithuania, existing from 1569 to 1795. This state was among the largest, most populated countries of 16th- to 18th-century Europe. At its peak in the early 17th century, the Commonwealth spanned approximately 1,000,000 km² (390,000 sq mi) and supported a multi-ethnic population of around 12 million as of 1618. The official languages of the Commonwealth were Polish and Latin, with Catholicism as the state religion.

The Polish–Russian War of 1792 was fought between the Polish–Lithuanian Commonwealth on one side, and the Targowica Confederation and the Russian Empire under Catherine the Great on the other.
