Yevgeny Viktorovich Prigozhin (1 June 1961 – 23 August 2023) 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.
