Europe is not a country, it is a continent. There are seven continents including Europe, Asia, North America, South America, Africa, Antarctica and Australia, which is the only continent that is also a country.
As of 2014, Europe is comprised of 47 countries and various smaller territories. There is a collection of 28 European countries that make up the European Union (EU). The main purpose of the EU is to foster mostly economic and some political cooperation for its members. It was formed after World War II as a means to assuage unrest that had resulted from extreme nationalism. Though there are strongly formed alliances between many European countries, they are still considered independent countries which are a part of the larger European continent.
