Which country won its first ever Olympic gold medal when athlete Kirani James won the Men's 400 metres in 2012?

Kirani James (born 1 September 1992) is a Grenadian sprinter who specializes in the 200 and 400 metres. Prodigious from a young age, he ran the fastest 400 m times ever by a 14-year-old and a 15-year-old. He won a series of gold medals at the CARIFTA Games and the Commonwealth Youth Games and rose on the international stage with 400 m silver medals at the 2007 World Youth and 2008 World Junior Championships. James became the first athlete to run a 200/400 double at the 2009 World Youth Championships and was the 2010 World Junior Champion.

On 6 August 2012, James won the 400m Olympic gold in a time of 43.94, a national record, earning Grenada its first ever Olympic medal and becoming the first non-US runner to break the 44-second mark. World record holder Michael Johnson said, following the race, that James stood a chance of beating his record if he was able to deal with the remaining flaws in his technique. James described his win as "a huge step for our country in terms of stepping up to the plate in track and field, just going out there and putting us on the map."
