[PAR] [TLE] Jamaica at the 2012 Summer Olympics [SEP] Jamaica competed at the 2012 Summer Olympics in London, from 27 July to 12 August 2012.  This was Jamaica's most successful performance in the Summer Olympics; it was approximately the same size from the previous games with a delegation of 50 athletes (25 men and 25 women), and its athletes broke the nation's record for the number of medals (all awarded in the track and field), won in a single games.  Jamaica's participation in London marked its sixteenth appearance as an independent nation, although it had previously competed in four other games (including the 1948 debut in the same host city London) as a British colony, and as part of the West Indies Federation.  Usain Bolt became the nation's greatest highlight of these games, having won three of Jamaica's four gold medals at London, and breaking an Olympic and world record in two of the three events in which he participated.  Because of his repeated successes for the most medals and records, Bolt became Jamaica's first male flag bearer at the opening ceremony since 1984.
