Which war in 2001 is subjectively deemed a world war?
World war A world war, as it is commonly understood, is a large-scale war involving many of the countries of the world or many of the most powerful and populous ones. World wars span multiple countries on multiple continents, with battles fought in many theaters. While a variety of global conflicts have been subjectively deemed "world wars", such as the Cold War and the War on Terror, the term is widely and generally accepted only as it is retrospectively applied to two major international conflicts that occurred during the 20th century: World War I (1914–1918) and World War II (1939–1945).

Most were civilian victims of the war crimes and crimes against humanity during the occupation by Nazi Germany and the Soviet Union. Statistics for Polish World War II casualties are divergent and contradictory. This article provides a summarization of these estimates of Poland's human losses in the war and their causes.
