Germany is a federal parliamentary republic in west-central Europe. The country consists of 16 states, and its capital and largest city is Berlin. Germany covers an area of 357,021 square kilo meters (137,847 sq mi) and has a largely temperate seasonal climate. With 81.8 million inhabitants, it is the most populous member state in the European Union. Germany is one of the major political and economic powers of the European continent and a historic leader in many theoretical and technical fields.
A region named Germania, inhabited by several Germanic peoples, was documented before AD 100. During the Migration Period, the Germanic tribes expanded southward and established successor kingdoms throughout much of Europe. Beginning in the 10th century, German territories formed a central part of the Holy Roman Empire. During the 16th century, northern German regions became the centre of the Protestant Reformation while southern and western parts remained dominated by Roman Catholic denominations, with the two factions clashing in the Thirty Years' War, marking the beginning of the Catholic–Protestant divide that has characterized German society ever since. Occupied during the Napoleonic Wars, the rise of Pan-Germanism inside the German Confederation resulted in the unification of most of the German states in 1871 into the German Empire, which was Prussian dominated.
After the German Revolution of 1918–1919 and the subsequent military surrender in World War I, the Empire was replaced by the parliamentary Weimar Republic in 1918, and some of its territory partitioned in the Treaty of Versailles. Despite its lead in many scientific and artistic fields at this time, amidst the Great Depression, the Third Reich was proclaimed in 1933. The latter period was marked by Fascism and World War II. After 1945, Germany was divided by allied occupation, and evolved into two states, East Germany and West Germany. In 1990 the country was reunified.
