Polish People's Republic
The Polish People's Republic (, ) was a state in Central Europe that existed from 1947 to 1989, and the predecessor of the modern democratic Republic of Poland. With a population of approximately 37.9 million inhabitants near the end of its existence, it was the most populous state of the Eastern Bloc after the Soviet Union. Having a unitary Marxist–Leninist communist government, it was also one of the main signatories of the Warsaw Pact. The official capital since 1947 and largest city was Warsaw, followed by industrial Łódź and cultural Kraków.

The period of Polish Enlightenment began in the 1730s–40s and peaked in the second half of the 18th century during the reign of Poland's last king, Stanisław August Poniatowski. It went into sharp decline with the Third and final Partition of Poland (1795), followed by political, cultural and economic destruction of the country, and leading to the Great Emigration of Polish elites. The Enlightenment ended around 1822, and was replaced by Polish Romanticism at home and abroad. The crowning achievements of Polish Enlightenment include the adoption of the Constitution of 3 May 1791, Europe's oldest written constitution as well as the creation of the Commission of National Education, the world's first ministry of education.
