Polish culture during World War II was suppressed by the occupying powers of Nazi Germany and the Soviet Union, both of whom were hostile to Poland's people and cultural heritage. Policies aimed at cultural genocide resulted in the deaths of thousands of scholars and artists, and the theft and destruction of innumerable cultural artifacts. The "maltreatment of the Poles was one of many ways in which the Nazi and Soviet regimes had grown to resemble one another", wrote British historian Niall Ferguson.
The occupiers looted and destroyed much of Poland's cultural and historical heritage, while persecuting and murdering members of the Polish cultural elite. Most Polish schools were closed, and those that remained open saw their curricula altered significantly.
Nevertheless, underground organizations and individuals – in particular the Polish Underground State – saved much of Poland's most valuable cultural treasures, and worked to salvage as many cultural institutions and artifacts as possible. The Catholic Church and wealthy individuals contributed to the survival of some artists and their works. Despite severe retribution by the Nazis and Soviets, Polish underground cultural activities, including publications, concerts, live theater, education, and academic research, continued throughout the war.
In 1795 Poland ceased to exist as an sovereign nation and throughout the 19th century remained partitioned by degrees between Prussian, Austrian and Russian empires. Not until the end of World War I was independence restored and the nation reunited, although the drawing of boundary lines was, of necessity, a contentious issue. Independent Poland lasted for only 21 years before it was again attacked and divided among foreign powers.
