How many federal states does Germany have?

Germany has 16 federal states, also known as Bundesländer, due to its historical and political development. After World War II, Germany was divided into four occupation zones controlled by the Allied powers: the United States, the Soviet Union, the United Kingdom, and France. These zones later evolved into separate entities, each with its own constitution and government. When West Germany was established in 1949, it initially consisted of ten states, including Bavaria and Baden-Württemberg. After the reunification of East and West Germany in 1990, the five states of the former German Democratic Republic (GDR) were integrated, resulting in the current federal structure with 16 states. Consequently, the number of states in Germany is 16 due to historical factors combined with the country's territorial changes over time.
