Germany, officially the Federal Republic of Germany (FRG), is a country in Central Europe. It lies between the Baltic and North Sea to the north and the Alps to the south. Its 16 constituent states have a total population of over 82 million in an area of 357,569 km² (138,058 sq mi), making it the most populous member state of the European Union. It borders Denmark to the north, Poland and Czechia to the east, Austria and Switzerland to the south, and France, Luxembourg, Belgium, and the Netherlands to the west. The nation's capital and most populous city is Berlin and its main financial centre is Frankfurt; the largest urban area is the Ruhr.

Settlement in what is now Germany began in the Lower Paleolithic, with various tribes inhabiting it from the Neolithic onward, chiefly the Celts. Various Germanic tribes have inhabited the northern parts of modern Germany since classical antiquity. A region named Germania was documented before AD 100. In 962, the Kingdom of Germany formed the bulk of the Holy Roman Empire. During the 16th century, northern German regions became the centre of the Protestant Reformation.
