Under Balestre's leadership FISA and the manufacturer-backed teams became involved in a dispute with FOCA (named the "FISA–FOCA war"). The conflict saw several races being cancelled or boycotted, and large-scale disagreement over the technical regulations and their enforcement. The dispute and the Concorde Agreement that was written to end it, would have significant ramifications for the FIA. The agreement led to FOCA acquiring commercial rights over Formula One, while FISA and the FIA would have control over sport's regulations. FOCA chief Bernie Ecclestone became an FIA Vice-President with control over promoting the FIA's World Championships, while FOCA legal advisor and former March Engineering manager Max Mosley would end up becoming FISA President in 1991. Mosley succeeded Balestre as President of the FIA in 1993 and restructured the organisation, dissolving FISA and placing motor racing under the direct management of the FIA.
