Joseph Stalin's real name was Ioseb Bessarionis dze Dzugashvili.

The statement is true. Joseph Stalin's real name was Ioseb Besarionis dze Dzugashvili. He was born on December 18, 1878, in Gori, Georgia, which was then part of the Russian Empire. Stalin adopted the pseudonym "Stalin," which means "man of steel" in Russian, later in his revolutionary career. However, his birth name, Ioseb Besarionis dze Dzugashvili, reflects his Georgian heritage and the naming conventions of the time.
