The Euphrates River flows through the region of what once used to be Mesopotamia. Today, the Euphrates is the largest River in Southwest Asia, with a length of 1,730 miles long. Together with the Tigris River, Ancient Mesopotamia was formed. During some of the first civilizations, small settlements that evolved into vast empires grew among the banks of the Euphrates. Back in ancient times, the Euphrates was used for transportation of people and resources. It has been referenced numerous times in the Judeo-Christian Bible. As mentioned in the Bible, God was the creator of the River.
