Ancient Egypt had a strong civilization that began around 3200 BC. The geography of Egypt, especially the flooding of the Nile River, supported the rise of Egyptian culture. Egyptians developed hieroglyphic writing, built pyramids and temples, practiced mummification, and had a society led by powerful pharaohs. Over time, foreign invaders like the Hyksos challenged Egyptian rule. The New Kingdom saw a revival of Egyptian power until internal struggles and outside pressures contributed to the decline of their empire, though Nubian kings later formed a Kush Empire influenced by Egyptian traditions.
