The Hyksos rulers of the 15th dynasty adopted and continued many of the existing Egyptian traditions in government as well as culture.
Around 1650 B.C., a line of foreign rulers known as the Hyksos took advantage of Egypt’s instability to take control. The Hyksos rulers of the 15th dynasty adopted and continued many of the existing Egyptian traditions in government as well as culture. They ruled concurrently with the line of native Theban rulers of the 17th dynasty, who retained control over most of southern Egypt despite having to pay taxes to the Hyksos. (The 16th dynasty is variously believed to be Theban or Hyksos rulers.) Conflict eventually flared between the two groups, and the Thebans launched a war against the Hyksos around 1570 B.C., driving them out of Egypt.
