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.
History of Poland
Critical developments of the Jagiellonian period were concentrated during Casimir IV's long reign, which lasted until 1492. In 1454, Royal Prussia was incorporated by Poland and the Thirteen Years' War of 1454–66 with the Teutonic state ensued. In 1466, the milestone Peace of Thorn was concluded. This treaty divided Prussia to create East Prussia, the future Duchy of Prussia, a separate entity that functioned as a fief of Poland under the administration of the Teutonic Knights. Poland also confronted the Ottoman Empire and the Crimean Tatars in the south, and in the east helped Lithuania fight the Grand Duchy of Moscow. The country was developing as a feudal state, with a predominantly agricultural economy and an increasingly dominant landed nobility. Kraków, the royal capital, was turning into a major academic and cultural center, and in 1473 the first printing press began operating there. With the growing importance of "szlachta" (middle and lower nobility), the king's council evolved to become by 1493 a bicameral General Sejm (parliament) that no longer represented exclusively top dignitaries of the realm.
