Early settlers began farming along the Nile river in Egypt around 7000 BC. Egyptians started using hieroglyphic writing around 3100 BC to record important information. The largest pyramid at Giza, built for Pharaoh Khufu between 2600-2500 BC, stands 147 meters tall and weighs around 6.5 million tonnes. Tutankhamun ruled Egypt for 9 years until 1327 BC and his tomb was discovered in 1922 by Howard Carter. Ramses II ruled for 66 years from 1279-1213 BC, building many temples and statues as a great military leader.
