Seti II
Goedicke suggests that Irsu rose to power in Egypt's territories abroad, in Canaan, following years of neglect on behalf of the last three pharaohs of the Nineteenth Dynasty, Seti II, Siptah and Twosret. According to this translation of the document, the earliest of these pharaohs, Seti II, is responsible for not asserting his power and control over the region; the second was held in low regard; while the last, Twosret, is said to have made an alliance with Irsu who had "de facto" authority over the territories.
