Knowing that the people did not really want to see him as a prince, he tried to attract Uleb , Lazar Sakovsky and Ivan Voitishich, who are respected in the city, to their side. Not wanting to openly conflict with the prince, Voitishich and his associates verbally supported Igor, but they secretly invited Izyaslav Mstislavich to reign. When he approached Kiev with the army, the governors came to meet him with the army of Igor Olgovich, but at the last minute before the battle they switched to Izyaslav's side, predicting the outcome of the struggle. ^{[2] [6]}
