Garshasp I

Garshasp I ibn Muhammad (Persian: گرشاسپ بن محمد), mostly known as Garshasp I, was the Kakuyid emir of Hamadan, including Nihawand, Borujerd and western Jibal. He was the youngest son of Muhammad ibn Rustam Dushmanziyar, and was the vassal king of his brother Faramurz. In 1047, the Seljuqs defeated his forces and seized Hamadan, which forced him to flee to Buyid territory, where he became governor of Khuzistan. In ca. 1050, Garshasp sent an army to aid the Ghaznavid ruler Maw'dud in his wars with the Seljuqs.^[1] Garshasp later died in 1051/2 in Khuzestan.^[2]
