The History of the Danube River Framed by some of the most picturesque and historical cities in the world, the Danube River is both captivating and charming. Recognized as Europe‟s second-longest waterway, the Danube River begins its journey from the springs in Germany‟s Black Forest and ends when it reaches the Black Sea.1 During the height of the Roman Empire, the river acted as a boundary that limited the movement of the Goths, Huns and Mongols into Roman territory. The commercial importance of the river escalated during the Crusades and then again in the 19th century. By the end of the Crimean War, the delta was cleared of obstructions and declared an international trade route.4 The expansive Danube River is 1,788 miles in length and, before reaching the Black Sea, forms the second largest and best preserved of Europe's deltas. With 2,200 square miles of rivers, canals, and marshes, the delta is rich in fauna and flora.3 Fascinating landmarks and sights line the banks of the river, attracting a variety of tourists from around the world. From avid birdwatchers to those in search of historical stimulation, the Danube River has something for everyone.
