Poland
However, Poland lost independence again not long after the beginning of World War II, after suffering a defeat by both the USSR and Nazi Germany. Although the government collapsed, the Polish people fought on by forming the largest and most effective resistance movement in Nazi-occupied Europe. It is most notable for disrupting German supply lines to the Eastern Front of WWII, providing military intelligence to the British, and for saving more Jewish lives in the Holocaust than any other Allied organization or government. After the war, Poland regained "independence" and became a communist country within the Eastern Bloc. The new government was appointed by Joseph Stalin and was under the control of the Soviet Union.
