Information:  - Europe is a continent that comprises the westernmost part of Eurasia. Europe is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, and the Mediterranean Sea to the south. To the east and southeast, Europe is generally considered as separated from Asia by the watershed divides of the Ural and Caucasus Mountains, the Ural River, the Caspian and Black Seas, and the waterways of the Turkish Straits. Yet the non-oceanic borders of Europea concept dating back to classical antiquityare arbitrary. The primarily physiographic term "continent" as applied to Europe also incorporates cultural and political elements whose discontinuities are not always reflected by the continent's current overland boundaries.  - The Volga is the longest river in Europe. It is also Europe's largest river in terms of discharge and watershed. The river flows through central Russia and into the Caspian Sea, and is widely regarded as the national river of Russia.  - The Caspian Sea is the largest enclosed inland body of water on Earth by area, variously classed as the world's largest lake or a full-fledged sea. It is in an endorheic basin (it has no outflows) located between Europe and Asia. It is bound by Kazakhstan to the northeast, Russia to the northwest, Azerbaijan to the west, Iran to the south, and Turkmenistan to the southeast.  - Khazaran was a city in the Khazar kingdom , located on the eastern bank of the lower Volga River . It was connected to Atil by a pontoon bridge . Khazaran was later inhabited primarily by Muslims and featured numerous mosques , minarets , and madrasas . It was a bustling trade center easily reachable by ship from the Caspian Sea and Volga River , and many of its inhabitants were crafters , fishers , and traders . The leader of the city was a Muslim official known as the Khazz ; in Arab sources the title given is sometimes vizier .  - A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river. In some cases a river flows into the ground and becomes dry at the end of its course without reaching another body of water. Small rivers can be referred to using names such as stream, creek, brook, rivulet, and rill. There are no official definitions for the generic term river as applied to geographic features, although in some countries or communities a stream is defined by its size. Many names for small rivers are specific to geographic location; examples are "run" in some parts of the United States, "burn" in Scotland and northeast England, and "beck" in northern England. Sometimes a river is defined as being larger than a creek, but not always: the language is vague.    Given the information, choose the subject and object entities that have the relation of 'country'.
