During the time of the Hyksos, Egypt was already deep into a civil war of their own. Because they were weakened when at war against each other, the Hyksos took advantage and invaded Egypt.
The Hyksos were a group of warriors from western Asia.
The Hyksos drove horse-drawn chariots.
The Hyksos used weapons made of bronze and iron.
The Hyksos ruled Egypt for over 100 years until an Egyptian prince named Ahmose drove them out of Egypt around 1550 BC.
