The Hyksos, a dynasty of Syro-Palestinian origin, rose to power in northern Egypt about 1630β1530 bce, due to an influx of immigrants from Palestine into Egypt. These immigrants brought new technologies such as the horse and chariot and improved weapons.
Prior to the beginning of the Hyksos dynasty, the 13th and 14th dynasties of Egypt weakened, possibly due to famine in the Nile Delta, paving the way for the Hyksos to establish their 15th dynasty.
