organisers and the CSI. The FIA and CSI were largely amateur organisations, and FOCA under the control of Bernie Ecclestone began to take charge of various aspects of organising the events, as well as setting terms with race organisers for the arrival of teams and the amount of prize money. This led to the FIA President Prince Metternich attempting to reassert its authority by appointing Jean-Marie Balestre as the head of the CSI in 1978, who promptly reformed the committee into the autonomous Fédération Internationale du Sport Automobile (FISA). 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. Following the 1994 San Marino Grand Prix, which saw the deaths of Ayrton Senna and Roland Ratzenberger, the FIA formed an Expert Advisory Safety Committee to research and improve safety in motor racing. Chaired by Formula One medical chief Professor Sid Watkins, the committee worked with the Motor Industry Research Association to strengthen the crash resistance of cars and the restraint systems and to improve drivers' personal safety. The recommendations of the committee led to significantly more stringent crash tests for racing vehicles, new safety standards for helmets and race suits, and the eventual introduction of the HANS device as compulsory in all international racing series. The committee also worked on improving circuit safety. This led to a number of changes at motor racing circuits around the world, and the improvement of crash barriers and trackside medical procedures. The FIA was a founder member of the European New Car Assessment Programme, a car safety programme that crash-tests new models and publishes safety reports on vehicles. Mosley was the first chairman
