The Hyksos were a group of mixed Semitic and Indo-European origin who settled in Egypt during the Second Intermediate Period (c. 1650–1550 BCE). They are known for introducing several technological advancements, including the horse-drawn chariot and new weapons, which contributed to their military dominance. The Hyksos eventually established the 15th Dynasty in Egypt and ruled large parts of the country until they were expelled by native Egyptian forces, leading to the eventual reunification of Egypt under the New Kingdom. Their presence significantly impacted Egyptian culture and politics during their rule.
