The Second Fatherland War was the term given by contemporary Russians to both the Eastern Front of World War I and the Eastern Front of World War II. Both terms attempted to link the current war with the French invasion of Russia in 1812, which had been termed the "Fatherland War" and later the "First Fatherland War". Both the "First Fatherland War" and the "Second Fatherland War" are used very rarely, with popular terms being "Patriotic War" () and "Great Patriotic War" () describing the wars against the armies of Napoleon and Hitler respectively.
