The Wagner Group, is a Russian state-funded private military company controlled by Yevgeny Prigozhin
Wagner became more evident in the Ukraine war when regular Russian troops suffered large casualties and lost ground in humiliating defeats.
Prigozhin visited Russian jails to recruit fighters, promising them pardons provided they completed a 6 month stint on the front lines with Wagner.
In January, He claimed entire credit for conquering the Donetsk region of Soledar in Ukraine, accusing the Russian Defence Ministry of attempting to take Wagner's glory.
He continually protested that the Russian military had not provided Wagner with enough ammunition to seize Bakhmut and threatened to withdraw his soldiers
On June 23, he called for an armed uprising against the defense minister and headed from Ukraine toward Moscow with his mercenaries.
Putin branded Prigozhin a traitor as the revolt unfolded. But the criminal case against the mercenary chief on rebellion charges was later dropped
