The Fertile Crescent (also known as the cradle of civilization) is a crescent-shaped region containing the comparatively moist and fertile land of otherwise arid and semi-arid Western Asia, the Nile Valley and Nile Delta. Having originated in the study of ancient history, the concept soon developed and today retains meanings in international geopolitics and diplomatic relations.
In current usage, all definitions of the Fertile Crescent include Mesopotamia, the land in and around the Tigris and Euphrates rivers; and the Levant, the eastern coast of the Mediterranean Sea. The modern-day countries with significant territory within the Fertile Crescent are Iraq, Syria, Lebanon, Cyprus, Jordan, Israel, the State of Palestine, Egypt, as well as the southeastern fringe of Turkey and the western fringes of Iran.
The region saw the development of some of the earliest human civilizations, which flourished thanks to the water supplies and agricultural resources available in the Fertile Crescent. Technological advances made in the region include the development of writing, glass, the wheel, agriculture, and the use of irrigation.
