Step-by-step explanation:
The people named Hyksos entered the world stage during the reign of Merneptah, marking the decline of the pharaohs' centralized control in Egypt. The Hyksos were Semitic-speaking chieftains who came from the Levant region and grew influential in Egypt's Nile delta due to increased trade. They eventually took control of certain areas, leading to the end of the Second Intermediate Period and the start of the New Kingdom under Ahmose I.
