After the Teutonic Order conquered and assimilated the Prussians, it began incursions into both Polish and Lithuanian territories. This represented a far greater threat to both Poland and Lithuania, and the two countries united in a defensive alliance by the crowning of the Lithuanian Duke Jogaila as King of Poland which led to a major confrontation at the Battle of Grunwald in 1410 and subsequent wars until 1525, when the Order became a vassal to the Polish Crown.

At its heyday, the Commonwealth comprised the territories of present-day Poland, and large parts of Ukraine, Belarus, Lithuania, Latvia, Estonia, and Russia, and represented a major European power. However, by the end of the 18th century a series of internal conflicts and wars with foreign enemies led to the dissolution of the Polish–Lithuanian Commonwealth and the partitioning of most of its dependent territories among other European powers. During the 18th century, European powers fought several wars for the control of the territories of the former Polish–Lithuanian Commonwealth. At the end of the 18th century, some Poles attempted to defend Poland from growing foreign influence in the country's internal affairs. These late attempts to preserve independence eventually failed, ultimately ending in Poland's partition and the final dissolution of the remains of the Polish–Lithuanian Commonwealth.
