The ancient Egyptian civilization lasted approximately 3000 years and was divided into nine distinct time periods. Daily life was structured around a social hierarchy with the pharaoh at the top. Most Egyptians lived in mud brick houses and ate a diet of bread and beer and some meat and fruits. Children started helping with work around age 5, and wealthy boys could attend school to learn reading, writing, and mathematics. Religion was the most important part of Egyptian life and centered around many gods. Art forms included painting, sculpture, architecture, and pottery.
