In reward for the brilliant services rendered him by Ertoghrul (the father of Osman) and by Osman himself, Ala-ud-din, the last of the Seljuk sultans, conferred certain provinces in fief upon these two great warriors.
Those who had not yet crossed the river refused, in face of this omen, to follow their brethren; the little band, numbering 400 warriors (according to others, consisting of 2000 horsemen) decided to remain under Ertoghrul, son of the drowned leader.
Ertoghrul first camped at Jessin, east of Erzerum; a second appeal to Ala-ud-din was more successful - the numbers of the immigrants had become too insignificant for their presence to be a source of danger.
The help afforded by Ertoghrul to the Seljukian monarch on a critical occasion led to the addition of Sugut to his fief, with which he was now formally invested.
Here Ertoghrul died in 1288 at the age of ninety, being succeeded in the leadership of the tribe by his son Osman.
