After World War II the responsibility for the security of Germany as a whole rested with the four Allied Powers: the United States, the United Kingdom, France and the Soviet Union. Germany had been without armed forces since the "Wehrmacht" was dissolved following World War II. When the Federal Republic of Germany was founded in 1949, it was without a military. Germany remained completely demilitarized and any plans for a German military were forbidden by Allied regulations. Some naval mine-sweeping units continued to exist, but they remained unarmed and under Allied control and did not serve as a national defence force. The Federal Border Protection Force, a mobile, lightly armed police force of 10,000 men, was formed on 14 March 1951 and expanded to 20,000 men on 19 June 1953. A proposal to integrate West German troops with soldiers of France, Belgium, the Netherlands, Luxembourg and Italy in a European Defence Community was proposed but never implemented.
