Strikeforce was a mixed martial arts (MMA) promotion based in the United States, founded in 1985. It gained popularity in the late 2000s and was known for hosting high-profile events featuring top fighters. The organization showcased various weight classes and helped elevate the sport's visibility. In 2011, Strikeforce was acquired by Zuffa, the parent company of the UFC. This acquisition led to the eventual dissolution of Strikeforce in 2013, with many of its fighters transitioning to the UFC. Despite its closure, Strikeforce is remembered for its contributions to the growth of MMA.
