 Since 1918 Mazovia has been a part of the resurrected Poland, being roughly equivalent to the Warsaw Voivodeship.Under the German occupation of Warsaw during World War II, the city's population decreased sharply as a result of executions, the extermination of the city's Jews, the deaths of some 200,000 inhabitants during the Warsaw Uprising of 1944, and the deportation of the city's left-bank population following the uprising.Shortly after the uprising, Adolf Hitler ordered German troops to destroy the city.
