Marne

The Marne is a major river in France that flows approximately 510 kilometers (about 317 miles) from east to west. It plays a significant role in regional geography, agriculture, and history. Historically, it was a battlefield during World War I, notably the Battles of the Marne in 1914 and 1918, which were pivotal in shaping the war's outcome. The river's fertile valley supports wine production and farming, and it flows through key cities like Reims and Chalons-en-Champagne. Overall, the Marne is important for its environmental, economic, and historical significance in northeastern France.
