Which river flows through Baghdad?

The Tigris River is the correct answer as it flows directly through Baghdad, which is the capital of Iraq. The Tigris, along with the Euphrates River, forms the Tigris-Euphrates river system, which is often referred to as the cradle of civilization due to its historical significance in the development of ancient Mesopotamia. Baghdad is strategically located between these two important rivers, but it is the Tigris that runs through the city itself, playing a vital role in its history, economy, and culture.

The Euphrates River, while also significant and located nearby, does not flow through Baghdad. Instead, it runs to the west of the city. The Nile and Amazon rivers are not relevant to this question as they are located in entirely different regions; the Nile is in northeastern Africa, while the Amazon flows through South America. Thus, it is the Tigris River that is central to Baghdad's geographic and historical identity.
