Plans foresaw the formation of six infantry, four armoured, and two mechanised infantry divisions, as the German contribution to the defense of Western Europe in the framework of a European Defence Community.[4] On 8 February 1952 the Bundestag approved a German contribution to the defense of Western Europe and on 26 February 1954 the Basic Law of the Republic was amended with the insertion of an article regarding the defence of the sovereignty of the federal government.[6] Following a decision at the London Nine Power Conference of 28 September to 3 October 1954, Germany's entry into NATO effective from 9 May 1955 was accepted as a replacement for the failed European Defence Community plan.
