The association was founded on 1 January 2000, and organises debates, spreads information and provides speakers to conferences. The cause for its foundation was the wedding of Prince Philippe and Princess Mathildein 1999. Some prominent members are Claude Boumal, Nadia Geerts and Philipp Bekaert, all three of them connected to the VUB-ULB. In 2011, the CRK had 'a few hundred members'. There are both Francophone and Dutch-speaking members, and according to Bekaert, with the exception of Vlaams Belang, almost all political parties are represented. The association is mainly trying to argue that the monarchy is a backward and undemocratic institute. It does not take a position on a potentialpartition of Belgium. Bekaert himself opined that Belgium is not 'too complex' to require a king for stability between the communities, because Switzerland, despite having its own linguistic conflicts, has not had any need for a monarch in its long republican tradition either. In August 2000, CRK members called for reopening the discussion about the monarchy. Amongst other things they recalled the Royal Question and the assassination of Julien Lahaut, who allegedly yelled "Vive la république!" during the inauguration of Baudouin on 11 August 1950, which was repeated by Jean-Pierre Van Rossem in 1993. They emphasised that 'the monarchy is not more legitimate today than yesterday'. On the occasion of the European Union's expansion on 1 May 2004, thirteen republican organisations from all the EU's monarchies petitioned the European Parliament to abolish the monarchy in the entire European Union. The petition was an initiative of the Republican Circle. From 2003 until 2007, the association annually awarded the 'Prize for Vocal Republican Citizenship' and the 'Prize for Submissiveness to His Majesty'. The CRK conducted an inquiry on how expensive a republic would be in comparison to a monarchy, and found that Belgian citizens pay three times the amount for their king then Germans do for President and a hundred times the amount the Swiss pay for their President. The CRK concluded that it's a 'myth' that republics are more expensive than monarchies, especially in the case of a parliamentary republic in which the president is appointed by Parliament without expensive direct elections. Since 2010, the CRK is member of the Alliance of European Republican Movements. In March 2013, the CRK hosted the AERM convention in Brussels.
