This is a relatively new weight category for professionals, first inaugurated by the major boxing sanctioning bodies between 1987 and 1990. History The minimumweight division was originally introduced in 1968 for the Summer Olympic Games under the name light flyweight. However the division was not recognized by any of the four most widely regarded sanctioning bodies until the International Boxing Federation (IBF) in June 1987 when Kyung-Yun Lee knocked out Masaharu Kawakami to become the inaugural champion. The division was then later recognized by the World Boxing Council (WBC) in October 1987, the World Boxing Association (WBA) in January 1988, and the World Boxing Organization (WBO) in August 1989, while Ring magazine did not begin ranking minimumweights until 1997 under the name strawweights and has yet to name a champion in their rankings. Historically the weight class has been dominated by Latin Americans and Asians with only a limited amount of success coming from other nationalities. Late 1980s (1987–1989) In the early years of the division, fighters such as Napa Kiatwanchai found success defending the WBC belt. Including early wins over a young up-and-coming Hiroki Ioka who later found success at light flyweight, flyweight, and super flyweight. Other notable champions of this period included Nico Thomas, Jum-Hwan Choi and Leo Gamez. Other successful fighters of this period include: Ricardo López - defended his WBC title against record-breaking 21 opponents. Ratanapol Sor Vorapin - IBF title-holder for most of the decade. Chana Porpaoin - held WBA title until losing the title to Rosendo Álvarez, who then held it until 1998 for failing to make weight for his unification rematch with Ricardo Lopez (he lost by split decision). The division also saw its first champions not from Latin America or Asia when Scotland's Paul Weir won the vacant WBO title over Fernando Martinez in May 1993. This was followed by South Africa's Zolani Petelo who won the IBF title in December 1997. Other notable fighters of this period included, Hi-Yong Choi, Hideyuki Ohashi, Alex Sánchez, Wandee Chor Chareon, Rocky Lin, Ala Villamor, Kermin Guardia, Noel Arambulet, Songkram Porpaoin, and Osvaldo Guerrero. 2000s In the early part of the decade, José Antonio Aguirre and Iván Calderón were the most decorated champions.
