What are the Tigris and Euphrates Rivers?

The Euphrates river is the longest and historically one of the most important rivers of South West Asia. The Tigris river together with the Euphrates river define Mesopotamia.

The Euphrates river - originating in the Taurus Mountains in Turkey- flows through Syria and Iraq to join the Tigris River near Basra, and from this junction to the Arabic (or Persian) Gulf the mass of moving water is known as the Shatt-al-Arab.

The Tigris river (1862 km long) originates from the Taurus Mountains in Eastern Turkey. The river then flows for 400 km through Turkish territory, before becoming the border between Syria and Iraq. This stretch of 44 km is the only part of the river that is located in Syria. The remaining 1418 km are entirely within the Iraqi borders.

The capital of Iraq, Baghdad, is located on the banks of the Tigris.

It is said that Tigris is one of the four rivers flowing from the Gardens of Eden.
