Tigris

The Tigris is one of the two great rivers that define Mesopotamia, along with the Euphrates. It flows south from the mountains of the Armenian Highlands through the Syrian and Arabian Deserts before joining the Euphrates and reaching the Persian Gulf.

The Tigris passes through important historical cities such as Mosul, Tikrit, Samarra, and Baghdad. It is also home to special archaeological sites and ancient communities, like the Mandaeans, who use its waters for baptism. In the past, the Tigris supported the powerful Assyrian Empire, and we can still see reminders of that time today.

Today, the Tigris faces challenges from things like changes in politics, building large dams, problems with water management, and changes in the climate. Because of this, people are worried about the river’s future. Local archaeologists and activists are working hard to protect and preserve the river’s important history and natural beauty.

Etymology

The name Tigris comes from many ancient languages. In Latin, it is called Tigris, and in Ancient Greek, it was Τίγρις (Tígris). This name likely began from a Sumerian phrase meaning "running water," which described the Tigris as a swift river compared to the slower Euphrates nearby.

The Sumerian name traveled into Akkadian as Idiqlat and then into other languages like Hebrew, Aramaic, Syriac, and Arabic. In Kurdish, the river is called Ava Mezin, meaning "the Great Water."

Geography

The Tigris River is 1,750 kilometers long. It starts in the Taurus Mountains in Turkey, near the city of Elazığ, and flows through southeastern Turkey. A small part of the river forms the border between Syria and Turkey.

As it gets closer to where it meets the Euphrates River, the Tigris splits into several smaller channels. One branch, called the Shatt al-Hayy, joins the Euphrates near Nasiriyah. Other channels feed marshes in the area. The main channel of the Tigris continues south and eventually joins the Euphrates near al-Qurnah to form the Shatt-al-Arab.

Important cities such as Baghdad, the capital of Iraq, and Basra are located along the Tigris. In ancient times, many great cities of Mesopotamia, like Nineveh and Ctesiphon, were built near the Tigris. These cities used the river’s water to help grow crops.

Navigation

The Tigris River has been a key path for travel in a dry, desert land. Small boats can reach as far as Baghdad, but rafts were often used for moving goods farther down the river from Mosul.

Management and water quality

The Tigris River has many dams built by Iraq and Turkey. These dams help provide water for farming in dry areas near the river. They also help prevent big floods that can happen when snow in the Turkish mountains melts in spring.

Recently, building dams on the Tigris by Turkey has caused some disagreements. People are worried about how it affects the environment in Turkey and whether it will reduce the amount of water that flows downstream.

In 2014, leaders from Iraq and Turkey agreed on a plan in Geneva to share information and set standards for managing the Tigris River’s water. In February 2016, warnings were issued that the Mosul Dam might fail, putting many people at risk in nearby areas.

Religion and mythology

In Sumerian mythology, the Tigris was made by the god Enki, who filled the river with water that flows.

The Tigris appears in old stories, like the Book of Genesis, where it is one of the rivers from the Garden of Eden. It is also where Daniel had a vision.
