Germany (Listeni/ˈdʒɜrməni/; German: Deutschland), officially the Federal Republic of Germany (German: Bundesrepublik Deutschland, pronounced [ˈbʊndəsʁepuˌbliːk ˈdɔʏtʃlant] ( listen))[15] is a federal parliamentary republic in western-central Europe. The country consists of 16 states and its capital and largest city is Berlin. Germany covers an area of 357,021 square kilometres (137,847 sq mi) and has a largely temperate seasonal climate. With 80.6 million inhabitants, it is the most populous member state in the European Union. Germany is the major economic and political power of the European continent and a historic leader in many cultural, theoretical and technical fields. Various Germanic tribes occupied what is now northern Germany and southern Scandinavia since classical antiquity. A region named Germania was documented by the Romans before AD 100. During the Migration Period that coincided with the decline of the Roman Empire, the Germanic tribes expanded southward and established kingdoms throughout much of Europe. Beginning in the 10th century, German territories formed a central part of the Holy Roman Empire.[16] During the 16th century, northern German regions became the centre of the Protestant Reformation. 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 dominated by Prussia. cong ty to chuc event công ty tổ chức sự kiện cong ty to chuc su kien chuyen nghiep to chuc su kien công ty tổ chức event
