Częstochowa Ghetto uprising
The Częstochowa Ghetto uprising was an insurrection in Poland's Częstochowa Ghetto against German occupational forces during World War II. It took place in late June 1943, resulting in some 2,000 Jews being killed. The ghetto was established following a day known as Bloody Monday, a day in which the Nazis killed 300 Jewish citizens in its occupation of the city of Częstochowa.
