The term "Rzeczpospolita" refers to a republic, particularly in the context of Polish history. It is most commonly associated with the Polish-Lithuanian Commonwealth, a significant political entity that existed from the 16th to the 18th centuries. This federation united the Kingdom of Poland and the Grand Duchy of Lithuania, creating a unique system of governance that emphasized noble democracy and shared power. In modern times, "Rzeczpospolita" is used to describe the Republic of Poland, established after World War I in 1918. The current constitution, adopted in 1997, outlines the principles of democracy, human rights, and the rule of law, reflecting Poland's commitment to a republican form of government.
