The law no 2010-1563 of 16 December 2010 to reform local authorities replaced the previous regime of merging communes defined in the "Marcellin" law of 16 July 1971 with a renewed consolidation procedure, resulting in the creation of a "new commune". It was supplemented in 2015 by a new law no 2015-292 of 16 March 2015 relating to the improvement of the regime of the new commune, for strong and lively communes, setting up temporary financial incentives in order to promote the creation of new municipalities before 1 January 2019.
