Catal Huyuk and Jericho were two of the earliest Neolithic cities in the region of Mesopotamia, located between the Tigris and Euphrates Rivers. Catal Huyuk, dating back to 8,000 BCE, was the oldest and largest city found from that period. Mesopotamia is considered the cradle of civilization as it was home to some of the earliest cities and civilizations, including the Sumerians who developed innovations in writing, mathematics, architecture, and more. Over thousands of years, different groups including the Akkadians, Babylonians, Assyrians, and Persians rose to power in Mesopotamia before falling to subsequent foreign invaders.
