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.

The official capital since 1947 and largest city was Warsaw, followed by industrial Łódź and cultural Kraków.
History of Poland (1795–1918)
At the outbreak of the First World War Poland's geographical position between Germany and Russia had meant much fighting and terrific human and material losses for the Poles between 1914 and 1918. At the Treaty of Brest-Litovsk in spring 1918, revolutionary Russia renounced Russian claims to Poland. Following the German defeat and the replacement of Hohenzollern rule by the Weimar Republic and the collapse of Habsburg Austria-Hungary, Poland became an independent republic.
