The Welterweight division is a weight class in boxing. In this division, the maximum weight is set at 147 lbs. while the minimum limit is 140.
The term was originally used in boxing, but over the years some of the other combat sports such Muay Thai, Taekwondo and Mixed Martial Arts have also adopted it in their weight classes in order to classify the fighters. Usually fighters in this class are heavier than the ones in the lightweight division but lighter than the middleweight division.
In the Welterweight division, Henry Armstrong holds the record for the most number of title defences. Armstrong defended his title 19 times. The longest reigning champion in the division was Puerto Rican Felix Trinidad who held the IBF Welterweight title for 6 years, 8 months and 14 days.
