The Treaty of Brussels, also referred to as the Brussels Pact, was the founding treaty of the Western Union (WU) between 1948 and 1954, when it was amended as the Modified Brussels Treaty (MTB) and served as the founding treaty of the Western European Union (WEU) until its termination in 2010. The treaty provided for the organisation of military, economic, social and cultural cooperation among member states as well as a mutual defence clause. The treaty was signed on 17 March 1948 by Belgium, France, Luxembourg, the Netherlands and the United Kingdom, the members of the Western Union, as an expansion to the Treaty of Dunkirk, which had been signed between Britain and France the previous year to guard against possible German or Soviet aggression after the end of World War II. The need to back up the commitments of the North Atlantic Treaty with appropriate political and military structures led to the creation of the North Atlantic Treaty Organization (NATO).
