History
The GPDA was founded in 1961 and was active during the 1960s and 1970s. Then, as now, the GPDA's primary objective was to improve and maintain safety standards. This led to boycotts of the Circuit de Spa-Francorchamps in 1969 and the Nürburgring in 1970 and after 1976.
The organisation was disbanded during the 1982 Formula One season due to the effects of the changing commercial organisation of F1 and the conflicts between FOCA and FIA.
The GPDA was reformed over the weekend of the 1994 Monaco Grand Prix, following the deaths of Ayrton Senna and Roland Ratzenberger, as well as the serious accident of Rubens Barrichello at the San Marino Grand Prix two weeks before.
