Instead of the Ruler Sultanshah, his brother, Turan-shah replaced him as the ruler of Kirman Seljuks State. In the following year of the enthronement of the Ruler Turan-shah (1085-86), he witnessed the social issues and problems resulting from the residence of some of the army in the houses of civil people within the city and he attempted to provide the necessary public works in order to prevent these kinds of problems. Pursuant to the death of the Ruler Kavurd, the Kirman Seljuks State had lost the neighbouring province of Fars for a specific period. The Ruler Turan-shah organised two military expeditions to Fars. He was defeated in the first one, but he organised a new army for the second exhibition and captured Fars.
Then, upon the death of Sultan Melikshah (1092), his wife, Terken Hatun was involved in a struggle in order to enthrone his younger son, Mahmud as the sovereign of the Great Seljuk State. The army that Terken Hatun sent in order to establish dominion in Fars was defeated by Turan-shah (1094).
Another event that took place in the period of Turan-shah was the rebellion of Oman people. However, this rebellion was suppressed and the Seljuk domination was restored in Oman. The Ruler Turan-shah reigned the state for thirteen years and died in October- November 1097.
