The Chacon vs. Limón series was four boxing fights between the American Bobby Chacon (1951–2016) and the Mexican Rafael Limón (born 1954). It was a rivalry that made history in the sport. Many sports historians consider Chacon–Limón to be among boxing's fiercest rivalries, alongside Ali–Frazier, Ali–Norton, Barrera–Morales, Vázquez–R. Márquez, Gatti–Ward, Louis–Schmeling, Durán–De Jesus, Leonard–Durán, Leonard–Hearns and Pacquiao–J.M. Márquez to name a few. Limón won on a ten-round decision in 1975. The 1979 match was declared a technical draw after an unintentional headbutt in round seven. Chacon won on a ten-round split decision in 1980. Chacon narrowly won again in 1982 after a knockdown of Limón with ten seconds left in the last of fifteen rounds. Prelude In order to examine this series of fights, a look at the history of relationships between Mexicans who were living in Mexico and Mexican-Americans (Chicanos or Tejanos) should be undertaken, Chacon was a Chicano, being born and raised in California. Limón is from Mexico. Southwest states like Arizona, New Mexico, Texas, Nevada and California were actually part of Northern Mexico before the United States took over those areas after the Mexican–American War. When the United States took over the states that border with Mexico, Hispanics predominated the area. As a consequence, many Mexican families abounded. After the United States took possession (Arizona and New Mexico became states in 1912), the children born afterwards to Mexicans who lived in these states became, legally speaking, Mexican-Americans or Americans with Mexican descent. Later on, other facts to be taken into consideration also took place. The coming of the Hollywood era, for example, should be taken into consideration. Being that Hollywood is in California, and the movie making industry made Hollywood an affluent city, many Hispanics, both Mexicans and Hispanics from other countries, were lured into trying their luck in California. Early Hollywood films, however, were responsible for a racist term used towards Mexicans: the term "greaser", an insulting word to Hispanics, was first used in the 1911 movie "Tony the Greaser", followed by 1914's "The Greaser's Revenge" and 1918's "Guns and Greasers". Hispanics who came into the United States during the early 20th century were usually farm workers, or had meek jobs when compared to other United States residents. Racism was considerable in the United States at that time; not only were Blacks relegated in the South, but many western area stores, restaurants and services segregated the
