During the 1970s, boxing was characterized by dominating champions and history-making rivalries. The decade had many superstars, who also had fierce rivals. Alexis Argüello, for example, who won the world Featherweight and Jr. Lightweight titles in the '70s, had to overcome Alfredo Escalera twice before the decade was over.
At least six divisions had world champions who could be considered dominant: The Bantamweights had Carlos Zárate; the Super Bantamweights, (a division created in 1976) had Wilfredo Gómez winning the title in 1977 and keeping it until he left it vacant in 1983; the Lightweights had Roberto Durán, who won the title in 1972 and vacated it in 1979 to seek championships at other weights; the Jr. Welterweights had Antonio Cervantes, who reigned twice; the Middleweights had Carlos Monzón, sometimes referred to as King Carlos because of his seven-year reign as champion; the Light-Heavyweights had Bob Foster. The Heavyweights had Muhammad Ali, who ruled twice between 1974 and 1979.[1]
