and two more were granted the same (Wezembeek-Oppem and Sint-Genesius-Rode/Rhode-Saint-Genèse). (Arguing that since 1947 many more people had shifted from Dutch to French, French-speaking Members of Parliament demanded that those six municipalities to be detached from the Dutch-speaking area and added to bilingual Brussels, which was fiercely resisted by their Flemish counterparts.) The same arrangement was made for a number of municipalities on new the border between the Dutch- and French-speaking areas, where local linguistic minorities could enjoy identical facilities: e.g. Flobecq and Enghien in the French-speaking area (where the Dutch-speaking minorities had reached respectively 7.2% and 12.1% in 1947); and Voeren/Fourons in the Dutch-speaking area (where the French-speaking population had reached 56.9% in 1947). In 1964, the Fédéralistes Démocrates Francophones (FDF), a party advocating the extension of Brussels, was founded. By 1970 all Belgian political parties had split into Dutch-speaking and French-speaking parties. The position of the linguistic border was endorsed in the 1970 State Reform (requiring a two-thirds majority) and, in return for contributing to this endorsement, the French-speaking minority was granted new measures which included the requirement of a special majority (a two-thirds majority in total and at least 50% in each linguistic group) to pass such laws as those of 1962 and 1963 in future; and (article 54) the possibility for any linguistic group to block a bill and open negotiations when it considers that such bill seriously jeopardizes its interests. According to the French-speaking parties, the compromise also included an agreement that in the future the existing voting and judicial opportunities for the large French-speaking minority around Brussels would be maintained and that the Brussels-Halle-Vilvoorde electoral and judicial arrondissement would remain unimpaired. The Flemish parties deny this, saying that this was never the intention. Importantly, these opportunities are not enshrined in the Constitution, but in law, and can be amended by a simple majority. Consequently, Bills intended at splitting the BHV arrondissement have been put forward several times and countered as many times by the French-speaking minority on grounds of the article 54 of the Belgian Constitution. 1970s–1990s The 1970 State reform also created the Dutch, French and German Cultural Communities and laid the foundations for the establishment of three Regions. Later on, in 1980, the Cultural Communities became known as Communities. Also two regions were established: the Flemish Region and the Walloon Region. Although the creation of a Brussels Region was provided for in
