FISA decided in 1955 that only a united German team could compete at international rowing championships; this first applied to European Championships and later, from the inaugural in 1962 onwards, to World Championships. This required that East and West Germany held selection trials, with the winning country for each boat class choosing the rowers who would compete at the championships. Over the years, the relationship between the two German countries deteriorated, and East Germany made seven application to FISA congresses to be recognised as a separate and independent country. On the seventh occasion, there was insufficient time to discuss the issue at the congress held in Duisburg just prior to the men's competition of the 1965 European Rowing Championships. FISA president Thomas Keller stated that an extraordinary congress were to be held in November in Vienna that would discuss the issue, and that he personally saw no problem with solving the problems. In October 1965, the International Olympic Committee decided that East Germany was to have its own team at future Olympic Games. At the FISA congress in November 1965, the East German application found forty-six votes of support, four abstentions (from Germany and Austria), and no votes of disapproval. At the same congress, Keller's proposal to not play national anthems or raise flags during medal ceremonies was also approved. These changes first applied at the European Championships (for women) in August 1966 and then the World Championships (for men) two weeks later in September.
