The term "Sugar" became a popular nickname for boxers during the early 20th century, particularly in the United States. The origin of the nickname can be traced back to a highly influential and revered boxer named Henry Armstrong, whose real name was Henry Jackson Jr. Armstrong. Armstrong was a three-division world champion during the 1930s, known for his exceptional speed, agility, and skill.


Armstrong was initially given the nickname "Melody Jackson" by his trainer, but it was later changed to "Sugar" by a sportswriter who was impressed by his smooth and sweet style of boxing. Armstrong's success and popularity contributed to the rise in the usage of the nickname "Sugar" for boxers.


After Armstrong, many boxers adopted the nickname "Sugar" as a way to pay homage to his legacy and emulate his skill and success. Some of the notable boxers who adopted the nickname include Sugar Ray Robinson (real name: Walker Smith Jr.), Sugar Ray Leonard (real name: Ray Charles Leonard), and Sugar Shane Mosley (real name: Shane Andre Mosley). These boxers, among others, were inspired by Henry Armstrong and sought to reflect his greatness by adopting the "Sugar" moniker.


It's important to note that the nickname "Sugar" doesn't hold any particular significance or meaning in relation to boxing itself. Instead, it was primarily used to evoke the association with the accomplished and highly regarded fighter, Henry Armstrong, and to convey a sense of skill, grace, and sweetness in the ring.
