Lucha libre is Mexico’s version of what in the United States refer to as pro wrestling. Its dates to 1863, when a Mexican wrestler named Enrique Ugartechea developed a form of “freestyle” wrestling that was based on Greco-Roman wrestling. Lucha libre began to soar in popularity in Mexico after two Italian businessmen started promoting fights in the early 1900s. It has since become popular around the globe.
