Which river is commonly known as the longest river in the world?

The Nile River is often recognized as the longest river in the world, with a length of about 6,650 kilometers (4,130 miles). It runs through eleven countries in northeastern Africa, flowing through regions rich in history and civilization, including Egypt, where it has played a crucial role in the development of ancient cultures. The river flows northward from Lake Victoria to the Mediterranean Sea, creating a vital water source for agriculture and sustaining millions of people along its banks.

While some recent studies have suggested that the Amazon River could be longer due to different methods of measurement and the inclusion of its tributaries, the Nile has traditionally held the title. This ongoing debate showcases the complexity of river systems and how geographical features can be interpreted differently based on various criteria. Nonetheless, for conventional classifications, the Nile is still primarily recognized and celebrated as the longest river.
