The 2011 Bahrain Grand Prix was cancelled due to civil unrest on 21 February 2011 at the request of Crown Prince Salman bin Hamad bin Isa Al Khalifa and the Bahrain Motor Federation. One month after an attempt by the FIA World Motor Sport Council to reinstate the race with an October date failed, the FIA released a provisional calendar for the 2012 season, re-instating the Bahrain Grand Prix. The event was originally given a November date so as to allow for stability to return to the country. A second provisional calendar was released in July, with the Bahrain Grand Prix brought forward to 22 April. This was later confirmed with the release of the final season calendar in December 2011.
