Malik-Shah I
Following Alp Arslan's assassination in 1072, Malik-Shah I was challenged in battle by his uncle, Kavurt. In January 1074, their armies met near Hamadan. Kavurt's troops consisted of the traditional Turkmen elements from Alp Arslan's army, while Malik's consisted of "ghulams" and contingents of Kurdish and Arab troops. Due to Turkmen defections to Malik's army, Kavurt was defeated and, despite Malik's consideration for mercy, later poisoned, presumably on the orders of Nizam al-Mulk.
