Banu Sumadih

The Banu Sumadih were an Islamic dynasty that ruled Almeria in Spain in the 11th century, subordinate to Zaragoza, until it was conquered by the Almoravids. Their last emir fled to the Hammadid king al-Mansur, who gave him command of Dellys in Algeria.

Its rulers were:

• Ma`n ibn Muhammad ibn Sumadih (1041-1051), installed by Zaragoza
• Al-Mu`tasim ibn Sumadih (1051-1091), a noted Arabic poet
• Mu`izz ud-Dawla ibn Sumadih (1091), fled to the Hammadids; granted command of Dellys from 1102.
