Stalingrad is also a brief way of referring to a vicious World War II battle taking place in the Russian city of Stalingrad from 1942–43--in terms of loss of human life, one of the costliest battles in history. See Battle of Stalingrad.

Stalingrad was, before the Russian Civil War, known as Tsaritsyn. The city was renamed, according to one source, owing to Stalin's victory over a White Russian force three times the size of his own during the civil war.
