Yevgeny Viktorovich Prigozhin (1 June 1961 – 23 August 2023) was a Russian mercenary leader, rebel commander, 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".
In 2014, Prigozhin reportedly founded the Wagner Group, which was used to support Russian separatist forces in Ukraine. Funded by the Russian state, it played a significant role in Russia's invasion of Ukraine and supported Russian interests in Syria and in Africa. In November 2022, Prigozhin acknowledged his companies' interference in United States elections.
