On 12 August 2006, the Iranian Football Federation decided to change the name of the league once again. The name of the league was initially the Persian Gulf Cup which later changed to the current name Persian Gulf Pro League. This was done to promote the name of the Persian Gulf, instead of the many variations which some nations and organizations use which Iran claims are incorrect. The league logo was also changed, with the winner being selected from over 130 designs and unveiled on 14 November 2006.
