Poland is a country in Eastern Europe. It was quite powerful in the 16th century, but fell into a long decline. During the 18th century, it was partitioned three times between Russia, Prussia, and Austria, eventually disappearing. Following World War I it was re-created as an independent nation, then fought a successful war against the Soviet Union.
During World War II, Poland was overrun by the Germans, then by the Soviets near the end of the war. The borders were redrawn, ceding territory to the Soviet Union but picking up more territory from Germany, moving the country to the west.
During the breakup of the Soviet Union, Poland was the first Eastern Bloc country to revolt successfully.
The capital is Warsaw.
