Third Islamic caliphate

The Abbasid Caliphate or Abbasid Empire was the third Islamic caliphate, ruled by the Abbasid dynasty. The dynasty was descended from Muhammad's uncle, Abbas ibn Abd al-Muttalib, after whom it is named. The Abbasids rose to power in 750, when the Abbasid Revolution overthrew the preceding Umayyad Caliphate. They ruled as caliphs from their base in Iraq until 1258, with Baghdad as their capital for most of their history.

The Abbasid Caliphate in Depth

History

The Abbasid caliphs descended from Abbas ibn Abd al-Muttalib, one of the youngest uncles of Muhammad and of the same Banu Hashim clan. This family relation to Muhammad made them appealing to those who were discontented with the rule of the Umayyad caliphs (661–750), who did not descend from the same family. Over the course of their rule, the Umayyads even suppressed several rebellions that attempted to bring other members of Muhammad's family to power. One of the claims that the Abbasids made in the early years of their political movement was that Abu Hashim, the son of Muhammad ibn al-Hanafiyya and grandson of Ali, had formally transferred the Imamate (imāmah) to Muhammad ibn Ali (the great-grandson of Abbas) and thus to the Abbasid family.

Military

The Abbasid army amassed an array of siege equipment, such as catapults, mangonels, battering rams, ladders, grappling irons, and hooks. All such weaponry was operated by military engineers. However, the primary siege weapon was the manjaniq, a type of siege weapon that was comparable to the trebuchet employed in Western medieval times. From the seventh century onward, it had largely replaced torsion artillery. By Harun al-Rashid's time, the Abbasid army employed fire grenades. The Abbasids also utilized field hospitals and ambulances drawn by camels. The cavalry was entirely covered in iron, with helmets. Similar to medieval knights, their only exposed spots were the end of their noses and small openings in front of their eyes.

Culture

The Abbasid historical period lasting to the Mongol conquest of Baghdad in 1258 CE is considered the Islamic Golden Age. The Islamic Golden Age was inaugurated by the middle of the 8th century by the ascension of the Abbasid Caliphate and the transfer of the capital from Damascus to Baghdad. The Abbasids were influenced by the Qur'anic injunctions and hadith, such as "the ink of a scholar is more holy than the blood of a martyr", stressing the value of knowledge. During this period the Muslim world became an intellectual center for science, philosophy, medicine and education as the Abbasids championed the cause of knowledge and established the House of Wisdom in Baghdad, where both Muslim and non-Muslim scholars sought to translate and gather all the world's knowledge into Arabic.

Imperial History & Territorial Expansion

Overthrowing the Umayyads in the 750 CE Abbasid Revolution, Caliph al-Mansur founded the circular planned city of Baghdad (Madinat al-Salam) along the Tigris. Under Harun al-Rashid—immortalized in the "One Thousand and One Nights"—and his son al-Ma'mun, Baghdad became the world’s intellectual capital. The House of Wisdom (Bayt al-Hikma) sponsored the Translation Movement, translating Greek, Sanskrit, and Persian manuscripts into Arabic, enabling polymaths like al-Khwarizmi (father of algebra) and Ibn al-Haytham (father of optics) to forge modern sciences.
