The Teotihuacan culture flourished in Mexico from around 200 BC to 700 AD, building a large civilization near present-day Mexico City known for its mysterious pyramids and temples. The Teotihuacan people practiced agriculture, growing crops like beans and tomatoes while also hunting deer, rabbits, and birds, and they domesticated turkeys and dogs. They had economic importance due to obsidian deposits and engaged in human and animal sacrifices, with priests controlling writing and knowledge. The Teotihuacan demonstrated mastery of mathematics, astronomy, and a numerical system using points and lines.
