Definition of 'Hyksos'

From: GCIDE

Hyksos \Hyk"sos\, n. [Gr. ?, fr. Egypt. hikshasu chiefs of the Bedouins, shepherds.] A dynasty of Egyptian kings, often called the {Shepherd kings}, of foreign origin, who, according to the narrative of Manetho, ruled for about 500 years, forming the XVth and XVIth dynasties. It is now considered that the XVIth is merely a double of the XVth dynasty, and that the total period of the six Hyksos kings was little more than 100 years. It is supposed that they were Asiatic Semites. [Webster 1913 Suppl.] Hylaeosaur
