Germany's invasion of Poland at the beginning of World War II led to the creation of the Polish Underground State, which opposed Hitler's conquests.
The Polish Underground State waged a WWII propaganda war, publishing newspapers and books. It created a symbol of resistance in the Anchor of Hope.
The Underground State worked to ensure the safety of their networks. It issued sentences against German officers and carried out their executions.
Poland's army continued to fight for liberation, and the Warsaw Uprising broke out. Stalin occupied Eastern Europe, and the Poles continued to fight.
