The Abbasid dynasty or Abbasids (Arabic: بنو العباس, romanizedBanu al-ʿAbbās) were an Arab dynasty that ruled the Abbasid Caliphate between 750 and 1258. They were from the Qurayshi Hashimid clan of Banu Abbas, descended from Abbas ibn Abd al-Muttalib. The Abbasid Caliphate is divided into three main periods: Early Abbasid era (750–861), Middle Abbasid era (861–936) and Later Abbasid era (936–1258). A cadet branch of the dynasty also ruled as ceremonial rulers for the Mamluk Sultanate as Caliph (1261–1517), until their conquest by the Ottoman Empire.
