Europe is one of the seven continents, and a peninsular sub-continent of the geographic continent Eurasia. Europe covers approximately 2% of the Earth's surface and about 6.8% of the planet's total land area. It hosts around fifty sovereign states, the precise number depending on the underlying definition of Europe's border, as well as on the inclusion or exclusion of states which are not fully recognised internationally. Europe has a population of 731,000,000 or about 11% of the world's population.
Europe is the birthplace of Western culture. European nations played a predominant role in global affairs from the 16th century onwards, especially after the beginning of colonization. By the 17th and 18th centuries European nations controlled most of Africa, the Americas, and large portions of Asia. World War I and World War II led to a decline in European dominance in world affairs as the United States and Soviet Union took prominence. The Cold War between those two superpowers divided Europe along the Iron Curtain. European integration led to the formation of the Council of Europe and the European Union in Western Europe, both of which have been expanding eastward since the fall of the Soviet Union in 1991.
