Muhammad I of Kerman

Muhammad Shah had a remarkably long reign of forty-two years. His succession to the throne in 1142 was marked by a violent power struggle; he seized and reportedly caused the death of his own father, Arslan Shah, and took the drastic measure of blinding or imprisoning approximately twenty of his brothers and nephews to secure his position. Despite this violent start, he maintained a stable household and was succeeded by his son.^[1]

The reign of Muhammad Shah I (1142–1156) is characterized by historians as the zenith of the Seljuq Sultanate of Kerman. Succeeding his father, Arslan Shah I, Muhammad I maintained a period of remarkable internal stability and economic prosperity that stood in contrast to the fragmentation occurring in the Great Seljuq Empire to the west.^[2] He is noted for his significant cultural patronage, specifically the establishment of numerous madrasas, libraries, and mosques in the city of Bardsir.^[3] His administrative reforms included the fortification of trade routes and the expansion of the qanat irrigation systems, which bolstered the province's agricultural output and social welfare.^[4] Upon his death in 1156, he was succeeded by his son, Tughrul Shah, leaving behind a kingdom at the height of its cultural and political influence.
