Hockey first appeared on the Olympic Programme in 1908 with Great Britain winning one gold, a silver and two bronze when competing as four separate Home Nations. The sport returned to the Games in 1920 and has been present ever since.
Played on artificial pitches rather than muddy fields these days, hockey matches Rio 2016 will be played in four 15-minute quarters rather than the two 35-minute halves of previous Games.
Team GB’s women won bronze at London 2012 and the last gold game at Seoul 1988 with the men’s team taking the victory.
India hold an impressive Olympic hockey record and once won seven out of eight men’s team gold medals between 1928 and 1964, winning silver in their only ‘failure’.
