Nizam al-Mulk
During his youth, he spent his time participating in the campaigns of his father Alp Arslan, along with the latter's vizier Nizam al-Mulk. During one of such campaigns in 1072, Alp Arslan was fatally wounded and died only a few days later. After that, Malik-Shah was crowned as the new sultan of the empire, but the succession was contested by his uncle Qavurt. Although Malik-Shah was the nominal head of the Seljuk state, Nizam al-Mulk held near absolute power during his reign. Malik-Shah spent the rest of his reign waging war against the Karakhanids on the eastern side, and establishing order in the Caucasus.
