During the Second World War, Palermo was heavily bombed by the Allied air forces in 1942 and 1943, until its capture during the Allied invasion of Sicily on 22 July 1943. The harbour (main objective of the air attacks) and the surrounding quarters were effectively destroyed, as was a considerable part of the city, with heavy civilian casualties. When American troops entered Palermo in 1943 they were greeted with "a thunderous welcome by what seemed the entire population demonstrating their feelings about Fascist rule." The two captured Italian generals claimed that they were happy because in their view "the Sicilians were not human beings but animals". Anti-sicilian prejudice was part of the fascist regime's world view, being promoted by pro-fascist newspapers, particularly in the north of Italy.
