The present name of the city is traditionally connected to the settlement Ltava which is mentioned in the Hypatian Chronicle in 1174. According to the chronicle, on Saint Peter's Day (12 July) of 1182, Igor Sviatoslavich, chasing hordes of the Cuman khans Konchak and Kobiak, crossed the Vorskla River near "Ltava" and moved towards Pereiaslav), where Igor's army was victorious over the Cumans. During the Mongol invasion of Rus' in 1238–39 many cities of the middle Dnieper region were destroyed, possibly including Ltava.
