Question: How old was Hisham II's father when he died? Passage 1:In 976, at the age of 11, Hisham II succeeded his father Al-Hakam II as Caliph of Cordoba. Hisham II was a minor at the time of his accession and therefore was unfit to rule. In order to benefit the Caliphate, his mother Subh was aided by first minister Jafar al-Mushafi to act as regents with al-Mansur ibn Abi Aamir (better known as "Almanzor") as her steward. In 978 Almanzor manipulated his way into the position of royal chamberlain. In an attempt to position himself as a prospective ruler of the Caliphate, Almanzor and General Ghalib al-Siklabi sabotaged the brother of Al-Hakam II who was set to succeed his brother and become the next Caliph of Cordoba. Too young to rule, Hisham II handed his political reins of power over to Almanzor in 981 who became the de facto leader of the Caliphate until his death in 1002. Al-Mansur ibn Abi Amir perpetuated his position as the omnipotent ruler in charge of the empire while he exiled Hisham II and essentially kept him prisoner leaving him impotent for most of his reign as the third Caliph of Cordoba. With his countless successful campaigns against Christian powers in the Spanish North such as Barcelona in 985, León in 988, as well as a major strike on the church of St. James in the Galician city of Santiago de Compostela in 998, Almanzor is known for bringing the Caliphate of Córdoba to its apex of power in Islamic Iberian history.
 Passage 2:The United States Supreme Court had ruled the Civil Rights Act of 1875 as unconstitutional in 1883. By the time of the convention the groundwork was laid for decades of segregation. On September 18, 1895, Booker T. Washington, an accommodationist, had given the Atlanta Exposition Speech, at the Cotton States and International Exposition. He was revered by followers and had critics such as William Monroe Trotter and W. E. B. Du Bois. An agreement was reached between black and white leaders that blacks would submit to white political rule in exchange for a guarantee of receiving basic education and due process in law. By 1890, Jim Crow Laws replaced black codes with a separate but equal status for black people. The United States Supreme Court Decision of Plessy v. Ferguson in 1896, stemming from the arrest of Homer Plessy in 1892, upheld racial segregation. Article 248 provided for free public separate schools, for "white and colored" races.
