On 23 June 2023, the Wagner Group, a Russian private military company, engaged in a major uprising against the Government of Russia. It marked the climax of the Wagner Group–Ministry of Defense conflict, which had begun about six months earlier. Russian oligarch Yevgeny Prigozhin, who had been leading Wagner Group activities in Ukraine, stood down after reaching an agreement a day later.

The Wagner Group, officially known as PMC Wagner, is a Russian state-funded private military company (PMC) controlled until 2023 by Yevgeny Prigozhin, a former close ally of Russia's president Vladimir Putin. The Wagner Group has used infrastructure of the Russian Armed Forces. Evidence suggests that Wagner has been used as a proxy by the Russian government, allowing it to have plausible deniability for military operations abroad, and hiding the true casualties of Russia's foreign interventions.
