History of Kurds
Taking advantage of the decline in the Buyid influence, in 984 he defeated Samsam al-Dawla, the sultan of the Buyids, and captured Mosul. Although he wanted to take Baghdad, he failed and had to evacuate Mosul. In 991, (Bad) Baz, who moved to capture Mosul again, was defeated by the Hamdanids, the rulers of the city, and died in this battle. His sister's son Abu Ali Hasan ibn Marwan ascended the throne in 990. Marwan made Mayyafariqin (Silvan) his capital. He continued to fight against the Hamdanids and defeated them twice. When Hasan ibn Marwan was assassinated in Amid (Diyarbakır) in 997, he was replaced by his brother Said ibn Marwan. The Marwanid dynasty, enjoyed considerable economic and cultural prosperity, but Kurdish, the mother tongue of the rulers of the dynasty, does not to have any visibility either in the administration or in the cultural life of the court. In 1085, the Seljuk army captured most of the region after a fierce battle.
