Polish-Lithuanian Commonwealth

dualistic state, a bi-confederation, of Poland and Lithuania ruled by a common monarch, who was both the King of Poland and the Grand Duke of Lithuania

The Polish–Lithuanian Commonwealth (or Union, after 1791 the Commonwealth of Poland) was a state of Poland and Lithuania ruled by a common monarch. The Commonwealth was an extension of the Polish-Lithuanian Union, a personal union between those two states that had existed from 1386. It was the largest[2] and one of the most populous countries of 16th- and 17th-century Europe. The Polish-Lithuanian Commonwealth covered more lands than the present lands of Poland and Lithuania. The lands of the Commonwealth also covered all the lands of present-day Belarus; a large part of Ukraine and Latvia; and western part of present-day Russia.

The Polish–Lithuanian Commonwealth had high levels of ethnic diversity and by religious tolerance.[3] The amount of religious freedom varied over time.[4]

After several decades of prosperity,[5] it entered a period of political,[6] military and economic[7] decline. It ended with the final Partitions of Poland in 1795. Its growing weakness led to it being divided by its more powerful neighbors, Austria, Prussia and the Russian Empire.
