Arising from the fact that the two areas neighbour each other, Richmond and Collingwood were both highly successful in the late 1920s to the early 1930s; the clubs played against each other in five grand finals between 1919 and 1929 (Collingwood won in 1919, 1927, 1928 and 1929, while Richmond won in 1920). In the 1980 Grand Final, Richmond handed Collingwood an 81 - point defeat, a record at the time.
