Алп-Арслан
Tughril had no children and thus had nominated his infant nephew Sulayman (a son of Chaghri Beg) as his successor. Kunduri supported this choice and may have been the one to suggest it to Tughril to greatly expand his authority as the regent of the child. However, Chaghri Beg's more competent and elder son Alp Arslan, who ruled Khurasan, opposed this choice and had the support of the competent bureaucrat Nizam al-Mulk, as well as a powerful army in Khurasan. Kunduri quickly included the name of Sulayman in the "khutba" (Friday sermon) of the capital of Ray. He subsequently contacted Alp Arslan, threatening him and telling him to be satisfied with dominion over Khurasan. Tughril's cousin Qutalmish also emerged as a contestant for the throne, which led to peace and cooperation between Kunduri and Alp Arslan, who defeated and killed Qutalmish outside Ray. Alp Arslan thus succeeded to the sultanate, and retained Kunduri as vizier. However, at the instigation of Nizam al-Mulk, Alp Arslan had Kunduri imprisoned in Marw-Rud on 31 December 1063 and also had his property confiscated. Nizam al-Mulk was then made the vizier of the sultanate. After approximately a year in prison, Kunduri was murdered by two slave-soldiers sent by Alp Arslan on 29 November 1064. Kunduri's sister took his body to Kundur, where it was buried.
