1950s and 1960s, the Volksunie (VU), once drew nearly one-quarter of Belgium's Dutch-speaking electorate away from the traditional parties. The Volksunie was in the forefront of a successful campaign by the country's Flemish population for cultural and political parity with the nation's long dominant French-speaking population. However, later on the party suffered severe setbacks and in October 2001 the party disintegrated. The social-liberal wing founded Spirit, later called the Social Liberal Party, while the more traditional Flemish nationalist wing continued under the banner New Flemish Alliance (N-VA). After a disappointing result in the regional elections of 2009, the Social Liberal Party decided to fuse with the Flemish ecologists of Groen. In the 2010 federal elections, the New Flemish Alliance became the biggest party and broke the domination of the traditional parties. Ecologists/Greens The Flemish ecologists (Groen, previously called Agalev and Groen!) made their parliamentary breakthrough in 1981. They focus heavily on environmental issues and investing in public transport to solve mobility issues. Their results generally remain stable, the greens were especially successful in the 1999 federal elections, after which they joined a federal coalition cabinet for the first time in their history, but were ousted after the next elections. They similarly joined Flemish governments in the 1999-2004 period. French-speaking minority The Union des Francophones (UF) is a Belgian electoral list which participates in regional, provincial and municipal elections in the Brussels Periphery, which is the part of the province of Flemish Brabant surrounding the bilingual Brussels Region. As the name suggests, its primary target are the French-speaking inhabitants of Flemish Brabant and particularly those who live in Halle-Vilvoorde and the predominantly French-speaking municipalities with linguistic facilities near the Brussels-Capital Region. The UF is a cooperation between the three most important French-speaking parties in Belgium: the Mouvement Réformateur, the Centre Démocrate Humaniste and the Parti Socialiste. The coalition wants an enlargement of the bilingual Brussels-Capital Region through the merger of various municipalities with linguistic facilities with a large percentage of French-speakers, like Sint-Genesius-Rode, and opposed the splitting of the bilingual Brussels-Halle-Vilvoorde electoral and judicial constituency. The party has one representative in the Flemish Parliament, five to six in the Flemish Brabant provincial council and several municipal councillors in the concerning towns. Communists The Kommunistische Partij (KP) is the successor in Flanders of the Kommunistische Partij van België (KPB), the first communist party in Belgium. This party was founded in 1921, but
