Josip Nikolai Peruzović (October 14, 1947 – July 29, 2018), better known by his ring name of Nikolai Volkoff, was a professional wrestler who is best known for his performances for the World Wrestling Federation. Although the Volkoff on-screen character was often portrayed as a villainous Russian, Peruzović actually originates from Croatia and has a mixed background. He was known for teaming with The Iron Sheik, with whom he won the WWF Tag Team Championship at WWE WrestleMania 1, and also with Boris Zukhov as The Bolsheviks. In 2005 he was inducted into the WWE Hall of Fame.
Volkoff died at home on July 29, 2018, at the age of 70, days after being released from a hospital in Maryland where he had been treated for dehydration and other issues.
