Yevgeny Viktorovich Prigozhin was a Russian mercenary leader and oligarch. He led the Wagner Group, a private military company, and was a close confidant of Russian president Vladimir Putin until launching a rebellion in June 2023. Prigozhin was sometimes referred to as "Putin's chef" because he owned restaurants and catering businesses that provided services to the Kremlin. Once a convict in the Soviet Union, Prigozhin controlled a network of influential companies whose operations, according to a 2020 investigation, were "tightly integrated with Russia's Defence Ministry and its intelligence arm, the GRU".
