The Danube is a major river in Europe. It is the second-longest river on the continent, after the Volga in Russia.

This river flows through Central and Southeastern Europe. It begins in the Black Forest of Germany. From there, it flows southeast toward the Black Sea. It eventually empties into the sea through the Danube Delta in Romania and Ukraine.

The river is a vital part of the European landscape. It serves as a major trade route and a source of water.

The river's journey begins through a specific process of confluence. The longest headstream is the Breg river. It rises in Furtwangen im Schwarzwald.

The Danube officially takes its name at the confluence of the Brigach and Breg rivers. This happens in the palace park at Donaueschingen.

From this point, the water flows southeast for approximately 2,850 kilometers. Along the way, many tributaries join the main flow. These tributaries include the Inn, the Drava, and the Tisza.

Each tributary adds more water to the river's total volume.

Geographers divide the Danube into three distinct stages. These stages are separated by "gates." These gates are places where the river cuts through mountainous sections. The first stage is the Upper Basin. It runs from the headwaters to the Devín Gate. The second stage is the Middle Basin. This is also called the Pannonian or Carpathian Basin. It lies between the Devín Gate and the Iron Gates. This area includes the Hungarian plains, known as the Alföld.

The final stage is the Lower Basin. It extends from the Iron Gates to the river mouth. This section includes the large Danube Delta.

History has long been shaped by this river. In ancient times, the Danube served as a frontier for the Roman Empire.

People have used the water for trade since ancient times. The river's name has changed many times throughout history. The ancient Greeks called it the Istros. In Latin, it was known as Danubius. The name "Danube" comes from this Latin root. Other languages use variations of this name. For example, Germans call it the Donau.

The river has connected different cultures for thousands of years.

The Danube is significant due to its massive scale. It passes through or borders ten different countries. These are Germany, Austria, Slovakia, Hungary, Croatia, Serbia, Romania, Bulgaria, Moldova, and Ukraine. The river also flows through four national capitals. These cities are Vienna, Bratislava, Budapest, and Belgrade.

The drainage basin covers 800,000 square kilometers. This basin extends into nine additional countries. This vast area is home to approximately 83 million people.

Life in the river is diverse and surprising. Many different fish species live in these waters. You can find pike, zander, and wels catfish. There are also sturgeon and various types of carp.

In the lower portions and the delta, euryhaline fish live there. These are fish that can handle different levels of salt. Examples include the European seabass, mullet, and eel. The river provides a rich habitat for these many species.

Today, the Danube is a busy system of transport and energy. A large part of the river is navigable.

This allows large barges to move goods across Europe. The river is even linked to the North Sea. This is done via the Rhine–Main–Danube Canal. The canal connects Kelheim on the Danube to Bamberg on the Main. The river is also used for hydropower.

This provides renewable energy. Finally, the river remains a critical source of drinking water for millions.
