Following U.S. independence from Great Britain, the U.S. established the first Consulate on German soil in Hamburg in June 1790, and the second one in Bremen in 1794, both independent German states at the time. The U.S. established diplomatic relations with the Kingdom of Prussia in 1797, then the German Empire in 1871. U.S.-German relations were terminated in 1917 during World War I, and the U.S. declared war on Germany. Relations were reestablished in 1921, but were severed again in 1941 during World War II when Nazi Germany declared war on the U.S. After the war, Germany was divided into four zones occupied by Allied powers; Berlin also was divided. In 1955, the U.S. established diplomatic relations with West Germany, which had been created out of the U.S., British, and French zones. The U.S. established diplomatic relations in 1974 with East Germany, which had been created from the Soviet Union's zone. West Germany and East Germany were unified in 1990.
Bilateral Economic Relations
EU Member States are collectively the U.S.’ biggest trading partner, and Germany, as Europe’s largest economy, is at the heart of that relationship. After China and the U.S., Germany is the world’s third-largest exporter. Every fourth job in Germany depends on exports, which accounted for 38.5% of Germany’s GDP in 2016 (three times the export share of U.S. GDP).
