By the 18th century, the Commonwealth was facing many internal problems and was vulnerable to foreign influences. The destabilization of the political system brought it to the brink of anarchy. Attempts at reform, such as those made by the Four-Year Sejm of 1788–92, which culminated in the May 3rd Constitution of 1791, 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. Poland and Lithuania re-established their independence, as separate countries, only in 1918.
