What is "timur-malik"

Timur-Malik, also spelled Temür Malik, the son of Urus Khan, was the ninth Khan of the White Horde. Early during his reign, he successfully invaded the lands of his cousin Toqtamysh. However, Toqtamysh later managed to trap and kill Timur-Malik near Qara-Tal (on the shore of the Aral Sea), and succeeded him. Temurmalik District in Tajikistan is named for him.
