World War II: Polish insurgents liberate a German labor camp (Gęsiówka) in Warsaw, freeing 348 Jewish prisoners.

A labor camp or work camp is a detention facility where inmates are forced to engage in penal labor as a form of punishment. Labor camps have many common aspects with slavery and with prisons. Conditions at labor camps vary widely depending on the operators. Convention no. 105 of the United Nations International Labour Organization (ILO), adopted internationally on 27 June 1957, intended to abolish camps of forced labor.

Gęsiówka is the colloquial Polish name for a prison that once existed on Gęsia ("Goose") Street in Warsaw, Poland, and which, under German occupation during World War II, became a Nazi concentration camp.

Warsaw, officially the Capital City of Warsaw, is the capital and largest city of Poland. The metropolis stands on the River Vistula in east-central Poland. Its population is officially estimated at 1.86 million residents within a greater metropolitan area of 3.27 million residents, which makes Warsaw the 6th most-populous city in the European Union. The city area measures 517 km² (200 sq mi) and comprises 18 districts, while the metropolitan area covers 6,100 km² (2,355 sq mi). Warsaw is classified as an alpha global city, a major political, economic and cultural hub, and the country's seat of government. It is also the capital of the Masovian Voivodeship.

Jews, or the Jewish people, are an ethnoreligious group and nation, originating from the Israelites of ancient Israel and Judah. They also traditionally adhere to Judaism. Jewish ethnicity, religion, and community are highly interrelated, as Judaism is their ethnic religion, though it is not practiced by many ethnic Jews. Despite this, religious Jews regard converts to Judaism as members of the Jewish nation, pursuant to the long-standing conversion process.
