Nasr al-Dawla ibn Marwan

Nasr al-Dawla ibn Marwan was the 4th emir of the Marwanid Dynasty and 5th of the Emirate. He overthrew the slave usurper Sharwin ibn Muhammad who had killed and overthrown his brother the very same year. He ruled from 1010 to 1061.

Reign
Early on he signed an nonaggression pact with the Eastern Roman Empire which was barely violated. In 1026 the people of Edessa willingly defected to him. The Romans tried to capture it in 1031, but lost it the next year. In 1054 he became a vassal of the rising Seljuk Empire. Although his reign was the apex of the emirate the Seljuk over lordship began the decay of the emirate. This would only be increased with his successor Nizam al-Dawla Nasr.
