Polish-Lithuanian Commonwealth

The Commonwealth covered not only the territories of what is now Poland and Lithuania, but also the entire territory of Belarus and Latvia, large parts of Ukraine and Estonia, and part of present-day western Russia (Smolensk and Kaliningrad).
By the 18th century, the Commonwealth was facing many internal problems and was vulnerable to foreign influences. Destabilization of its political system brought it to the brink of anarchy. Attempts at reform came too late, and the country was partitioned in
three stages by the neighboring Russian Empire, Kingdom of Prussia, and the Habsburg Monarchy. By 1795, the Polish–Lithuanian Commonwealth had been completely erased from the map of Europe.
