Brothers in earlier Turkic tradition usually participated in government affairs, unlike later Ottoman practice. (Notable examples are Bumin and İstemi in the sixth century, and Bilge Khan and Kultegin in the eighth century.)

Tughril and Chaghri, as well as some other members of the Seljuq family, have participated in the foundation of the empire.

Although Tughril has gained the title "sultan", it is Chaghri’s sons who will continue it afterwards.

Chaghri dies in Sarakhs, in northeastern Iran, a stopping point along the Silk Road, and in its eleventh century heyday boasting many libraries and a famous school of architects.

The historical sources do not agree on the exact date of Chaghri’s death: the years 1059, 1060, 1061 and 1062 had been proposed, but it is purported that numismatics can be used to determine the exact death date.

Coins were minted in the name of Chaghri up to 1059 and in the name of his son Kavurt after 1060, so Chaghri's death can be ascribed more probably to 1059.

Muhammad bin Dawud, later known as Alp Arslan, succeeds his father as governor of Khorasan.
