At which World Championships did Usain Bolt win his first individual world title?

Usain Bolt won his first individual world title at the 2009 World Championships in Berlin. He captured the men's 100 metres gold medal in a world-record time of 9.58 seconds.

The victory came a year after Bolt's breakthrough at the 2008 Beijing Olympics, where he won Olympic gold in both the 100 metres and 200 metres. Olympic success, however, is separate from winning an individual World Championships title.

Bolt had already appeared at the 2007 World Championships in Osaka, winning silver in the 200 metres and helping Jamaica take silver in the 4 × 100 metres relay. In Berlin, he followed the 100-metre victory with another individual gold in the 200 metres, setting a world record of 19.19 seconds.

A common mix-up is 2011: Bolt won the 200 metres there, but he was disqualified for a false start in the 100-metre final. His first world title was therefore in 2009, not 2007 or 2011.
