Wagner Group
The Wagner Group started in 2014 when Russia took over Crimea. Until 2022, it wasn't clear who started and ran the group. Dmitry Utkin and Yevgeny Prigozhin were both named as founders and leaders. During Russia's invasion of Ukraine, Prigozhin said he started Wagner and was its head. Some sources say Prigozhin paid for it, while Utkin led its military side.
