		During the reign of Marwan II this opposition culminated in the rebellion ofIbrahim the Imam, the fourth in descent from Abbas, who, supported by the province of Khorasan, achieved considerable successes, but was captured (AD 747) and diedin prison (as some hold, assassinated).
		The quarrel was taken up by his brother Abdallah, known by the name of Abu al-'Abbasas-Saffah, who, after a decisive victory on the Greater Zab river (750), finally crushed the Umayyads and was proclaimed Caliph.
		Abu al-'Abbas' successor,Mansur, moved their capital from Damascusto the new city of Baghdad and welcomed non-Arab Muslims to their court.

	Mansur (print-only)
		Abu Nasr Mansur was a native of Gilan which is mentioned in The Regions of the World, a Persian geography book of 982.
		Abu Nasr Mansur's main achievements are his commentry on the Spherics of Menelaus, his role in the development of trigonometry from Ptolemy's calculation with chords towards the trigonometric functions used today, and his development of a set of tables which give easy numerical solutions to typical problems of spherical astronomy.
		Abu Nasr Mansur's treatise discusses the five trigonometric functions which are used to solve problems in spherical astronomy.

		Abu Nidal died of between one and four gunshot wounds in Baghdad in August 2002, believed by Palestinian sources to have been killed on the orders of Saddam Hussein, [2] but said by the Iraqi government to have committed suicide.
		Abu Nidal's first operation took place on September 5, 1973, when five gunmen seized the Saudi embassy in Paris, taking 13 hostages and threatening to blow up the building if Abu Dawud was not released from jail in Jordan, where he had been arrested in February 1973 for an attempt on the King's life.
		Abu Nidal is known to have entered Iraq in 1999 after being expelled from Libya by Gaddafi, who was distancing himself from terrorism in an effort to re-establish diplomatic relations with the U.S. and UK after Lockerbie.

		The history of the new dynasty is marked by perpetual strife and the development of luxury and the liberal arts, in place of what their opponents identified as old-fashioned austerity of thought and manners.
		The Abbasids also persecuted descendants of Ali ibn Abu Talib viewing them as threats, and this in turn earned the dynasty great disfavor with the Shia, who lost many of their leaders to the Abbasids.
		Mansur, the second of the house, who transferred the seat of government to the new city of Baghdad, fought successfully against the peoples of Asia Minor, and the reigns of Harun al-Rashid (786 - 809) and al-Ma'mun (813 - 833) were periods of extraordinary splendour.

		Abu al-'Abbas' successor, al-Mansur, moved their capital from Damascus to the new city of Baghdad and welcomed non-Arab Muslims to their court.
		In addition, the period saw the recovery of much of the Alexandrian mathematical, geometric and astronomical knowledge, such as that of Euclides and Claudius Ptolemy.
		These recovered mathematical methods were later enhanced and developed by other Islamic scholars, notably by Al-Biruni, and Abu Nasr Mansur.

		In addition, in the late 10th century Abu al-Wafa` and the prince Abu Nasr Mansur stated and proved theorems of plane and spherical geometry that could be applied by astronomers and geographers, including the laws of sines and tangents.
		Abu Nasr's pupil al- Biruni (973-1050), who produced a vast amount of high-quality work, was one of the masters in applying these theorems to astronomy and to such problems in mathematical geography as the determination of latitudes and longitudes, the distances between cities, and the direction from one city to another.

		Although there is no reason to doubt al-Tusi that the proof he gives does indeed come from al-Khujandi there is quite a few reason to believe that one of Abu'l-Wafa or Abu Nasr Mansur was the original discoverer.
		Both Abu'l-Wafa and Abu Nasr Mansur claim to have discovered the sine theorem while, as far as we are aware, al-Khujandi makes no such claim.
		Finally, although this really proves little, the theorem appears many times in the writings of Abu Nasr Mansur both his writings on geometry as well as those on astronomy.
