Westdeutschland, or West Germany, was the official name for the Federal Republic of Germany from its establishment in 1949 until reunification in 1990. It was formed in response to the division of Germany after World War II, with the western part being influenced by the United States and Western Europe. The capital was Bonn, and the country was known for its strong economy and democratic government. During its existence, West Germany became a key member of NATO and the European Economic Community, promoting economic cooperation in Europe. The country experienced significant growth and modernization, often referred to as the "Wirtschaftswunder" or economic miracle, which transformed it into one of the world's leading economies.
