What was the Abbasid dynasty known for?

The Abbasids overthrew the Umayyad dynasty in 750 CE, supporting the mawali, or non-Arab Muslims, by moving the capital to Baghdad in 762 CE. The Persian bureaucracy slowly replaced the old Arab aristocracy as the Abbasids established the new positions of vizier and emir to delegate their central authority. 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.

Similarly, what led to the decline of the Abbasid dynasty? The invasion of the Mongols, who sack Baghdad. So to sum it up, the Abbasid Empire fell down due to these reasons: Power struggles, and an unorganized method for succession. Invasions (alot of them). The Abbasids, who ruled from Baghdad, had an unbroken line of caliphs for over three centuries, consolidating Islamic rule and cultivating great intellectual and cultural developments in the Middle East in the Golden Age of Islam. The Abbasid Caliphate had two major periods. During this period, the Abbasids were strong leaders who controlled a vast territory and created a culture that is often referred as the Golden Age of Islam. In 1258 CE, however, the capital city of Baghdad was sacked by the Mongols causing the Abbasids to flee to Egypt.
