Question: Question: Who succeeded Khalid's son as ruler of  the family's stronghold? Passage:Khalid was a member of the Shayban tribe, dominant in the region of Diyar Bakr in the northern Jazira, and third son of Yazid ibn Mazyad al-Shaybani, who served twice as Arab governor (ostikan) of Arminiya (a large province encompassing the whole of Transcaucasia). Khalid served in the same office no less than four times: in 813/814, 828–832, briefly in 841 and again under Caliph al-Wathiq (r. 842–845). In his first tenure, he showed himself conciliatory towards the native Christian population and the nakharar princes, but his second tenure was marked by the brutal suppression of several revolts by local Arab magnates, as well as the harsh treatment of the Christian population. As a result, when his re-appointment to the office was announced in 841, a rebellion broke out, forcing the Abbasid government to recall him immediately. Nevertheless, al-Wathiq assigned Arminiya to Khalid. The latter arrived in the province at the head of an army, and crushed any opposition. He died soon after at Dvin, where he was buried. He was succeeded by his son, Muhammad. His younger son Haytham ibn Khalid ruled in the family's stronghold of Shirvan, and was the first to claim the title of Shirvanshah.

Question: Question: What other notable people studied the same disciplines in the university Kapp was at between 1842 and 1844? Passage:Kapp received his Abitur from Gymnasium “Hammonense”, the same educational institution where his father held the position of principal. Between 1842 and 1844, Kapp studied law and philosophy at the University of Heidelberg. There, at his uncle Christian Kapp's (1798–1874) house, he met the philosopher Ludwig Feuerbach. Not only did they become close friends; Feuerbach's criticism of religion, which also strongly influenced Karl Marx, had a great impact on Kapp's attitude towards life as well. Other acquaintances from his time as a student were Ludwig Bamberger (1823–1899), who would later become a banker, the author Berthold Auerbach (1812–1882) of Heidelberg and the poet Bettina von Arnim (1785–1859) of Berlin. From 1844 on, Kapp studied at the University of Berlin and voluntarily served in the army for one year. In Berlin, he was already working as a journalist for the utopian socialist magazine called "Westfälisches Dampfboot" ("Westfalian Steamboat").

Question: Question: How old was John Gorham when he formed Gorham's Rangers? Passage:Gorham's Rangers was one of the most famous and effective ranger units raised in the colonial North America. Formed by John Gorham, the unit served as the prototype for many subsequent ranger forces, including the better known Rogers' Rangers. The unit started out as a Massachusetts provincial auxiliary company, which means it was not part of the province's normal militia system. Recruited in the summer of 1744 at the start of King George's War, Governor William Shirley ordered the unit raised as reinforcements for the then-besieged British garrison at Fort Anne in Annapolis Royal. Over the next eight years the unit proved remarkably effective at suppressing Acadian and Mi'kmaq resistance to British rule in Nova Scotia and helped to both expand and secure the British sphere of influence in the region. Initially a sixty-man all-Indian company led by British colonial officers, the original Native American members of the unit were gradually replaced by Anglo-Americans and recent Scots and Irish immigrants and were a minority in the unit by the mid-1750s. The company were reconnaissance experts as well as renowned for their expertise at both water-borne operations and frontier guerrilla warfare. They were known for surprise amphibious raids on Acadian and Mi'kmaq coastal or riverine settlements, using large whaleboats, which carried between ten and fifteen rangers each. This small unit was the main British military force defending Nova Scotia from 1744 to 1749. The company became part of the British army and was expanded during the Seven Years' War and went on to play an important role in fighting in Nova Scotia as well as participating in many of the important campaigns of the war, particularly distinguishing itself at the Siege of Quebec in 1759.
