Eastern Europe is a subregion of the European continent. As a largely ambiguous term, it has a wide range of geopolitical, geographical, ethnic, cultural, and socio-economic connotations. Its eastern boundary is marked by the Ural Mountains, whilst its western boundary is defined in various ways. Most definitions include the countries of Belarus, Russia, Ukraine, Moldova, and Romania while less restrictive definitions may also include some or all of the Balkans, the Baltic states, the Caucasus, and the Visegrád group.
Europe, the westernmost portion of Eurasia, is often divided into regions and subregions based on geographical, cultural or historical factors. Since there is no universal agreement on Europe's regional composition, the placement of individual countries may vary based on criteria being used. For instance, the Balkans is a distinct geographical region within Europe, but individual countries may alternatively be grouped into South-eastern Europe or Southern Europe.
