This Commonwealth Games results index is a list of links which forms an "index" which can be used to quickly find the required Wikipedia page containing the results of each Commonwealth Games sport in any year of interest.  Previously these games were known as The British Empire Games (1930-1950), The British Empire and Commonwealth Games (1954-1966) and The British Commonwealth Games (1970-1974).  Years appearing in red are those for which there is no corresponding article. Due to the success of the first 1930 British Empire Games in Hamilton, Canada, a meeting of representatives from Great Britain, its colonies and territories decided that the games, similar to the Olympic Games should be held every four years, and that an authoritative organisation should be formed.  Following the 1932 Summer Olympics, it was decided to form the ""British Empire Games Federation"" who would be responsible for the organising of the games.  The name of the federation was changed in 1952 to the ""British Empire and Commonwealth Games Federation"", and again in Jamaica in 1966 to the ""British Commonwealth Games Federation"", until eventually being changed again in Christchurch, New Zealand in 1974 to the ""Commonwealth Games Federation"".
