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.
Kingdom of Poland (1917–1918)
In the meantime, General von Beseler had managed to gain support among pro-Austrian Poles and the followers of Józef Piłsudski. The Narodowa Demokracja party (centred in Paris), however, rejected any cooperation with the Central Powers. After the German Emperor and Chancellor met with a Polish delegation led by Józef Brudziński, the final details were arranged. On November 5, 1916, Governor von Beseler at Warsaw issued an Act of November 5, in which he promised that a Polish state would be created, without specifying any future Polish ruler, Polish borders or system of governance and, for the first time since 1831, had the Royal Castle decorated with Polish flags. The Austrian Governor-General Kuk issued a similar proclamation at Lublin. A pro-German faction led by Władysław Studnicki existed but didn't gain any significant backing among Polish population.
