WBA
The first of four major professional boxing organizations - the World Boxing Association (WBA) was born in Rhode Island in 1921 as the National Boxing Association (NBA), and the first boxing title fight recognized by the new Association was the Heavyweight bout between Jack DEMPSEY and Georges CARPENTIER on July 2, 1921.
Jack Dempsey beat his rival by knockout in the 4th round and became the first WBA boxing champion. The NBA was founded to counter the influence of the New York State Athletic Commission (NYSAC), established one year early. Both organizations crowned different boxing world champions in the same division, leading to a discussion about who was the true world champion.

WBC
On February 14, 1963, at a meeting of representatives of 11 countries: USA, Argentina, Brazil, Chile, France, Great Britain, Mexico, Panama, Peru, Philippines, and Venezuela in Mexico City was created the first real international boxing organization - World Boxing Council (WBC). New York State Athletic Commission (NYSAC), a rival of the WBA in world boxing, supported the new organization and was adopted into WBC in 1970.

IBF
In April 1983, the members of the United States Boxing Association (USBA) decided the regional status of the organization extended to international. A new boxing organization got the name United States Boxing Association-International (USBA-I), and Robert W. Lee, Sr., president of the USBA, who lost in his bid to become WBA president against Gilberto Mendoza in 1982, led the USBA-I.

WBO
The World Boxing Organization (WBO) is the last of four major professional boxing organizations that currently recognize professional boxing world champions. It was formed in 1988 after the scandal at the WBA annual meeting in Isla Margarita, Venezuela, when a group of Puerto Rican and Dominican businessmen complained about the existing WBA's questionable rules and ratings systems.
