The Second Intermediate Period dates from 1782 to 1550 BC. It marks a period when ancient Egypt was divided into smaller dynasties for a second time, between the end of the Middle Kingdom and the start of the New Kingdom. The concept of a Second Intermediate Period generally includes the 13th through to the 17th dynasties; however, there is no universal agreement in Egyptology about how to define the period.
It is best known as the period when the Hyksos people of West Asia established the 15th Dynasty and ruled from Avaris, which, according to Manetho's Aegyptiaca, was founded by a king by the name of Salitis. The settling of these people may have occurred peacefully, although later recounts of Manetho portray the Hyksos "as violent conquerors and oppressors of Egypt".
