The EGU was founded in 1992 by representatives of the gliding associations of Belgium, France, Germany, the Netherlands, Spain, Sweden and the United Kingdom. Its statutes were adopted at the first congress held in Strasbourg on the 1st of October 1993 and updated in 2016. The aim of the EGU is to be the independent representative of the interests of all glider pilots in Europe with respect to regulatory affairs.
