In 1241 the chiefs of this settlement sent to the Grand Khan for more people. At the end of five months two hundred new families were added to Herat. A census taken the year following showed the city as having six thousand nine hundred inhabitants. In following years the increase became rapid. On arriving at Tus Kurguz put a kang on his enemy Sherif. He drew from him afterward confessions which were sent to the court in Mongolia. His messenger learned on the road that the Grand Khan was dead. Kurguz himself had set out to explain the whole system introduced by him recently in Persia. While passing through Transoxiana he had a quarrel with an officer of Jagatai’s household. Threatened with complaint before that prince’s widow he replied that he cared not. This answer when taken to the widow roused wrath and keen hatred. Alarmed by the quarrel and hearing of Ogotai’s death with the loss of protection, he judged best to turn back and he did so. Meanwhile the wife of Sherif had sent people promptly to the Jinghis Khan princes imploring protection for her husband. Those messengers had been seized on the way save one among all of them. This man escaped and reached Ulug Iff, the chief residence of Jagatai, whose wives and sons sent Argun out with orders to bring them Kurguz of his own will or, if need be, in spite of him. On hearing this order Kurguz, who had given Sherif to the prefect of Sebzevar who was to kill him, sent command straightway to stay the execution. When Argun was approaching, Kurguz found retreat in a storehouse. Since the governor would not yield himself willingly, Argun required aid of the district commanders and got it. These men were all foes of Kurguz since he had fought their abuses. When they were ready to burst in and take him, he threw the gates open declaring that he was no enemy. Kurguz was taken to Jagatai’s sons and examined. After that he was sent to the court of Turakina, Ogotai’s widow, who was regent in Mongolia. Chinkai, his protector, was gone. He had fled from the hatred of the regent which intrigue had roused wrongfully against him. To crown his misfortune, the governor of Persia was penniless, hence had no power to establish his innocence. He was sent back at command of the regent to Jagatai’s sons to be judged by them. He answered straightforwardly all questions which they put to him, nevertheless, Kara Hulagu adjudged death to the governor. His mouth was crammed then with earth and in that way they strangled and killed him.
