YLO was originally created by the Young Lords in 1970. When Young Lords began to disband in the mid-1970s some members relocated to the Logan Square and West Humboldt Park neighborhoods where they cliqued up with Spanish Cobras and Maniac Latin Disciples. The Young Lords then assimilated with the Disciples and Cobras in 1976. In the year 1976, the Spanish Cobras and Latin Disciples drew up this official alliance in order to team up and fight against Latin Kings and UFO allied gangs. The alliance was known as “Young Latino Organization.” In 1978 the YLO was replaced by ULO, but YLO continued as a training camp for young future Cobras and Disciples, in 1979 they stole the YLO name to create their own gang called the “YLO Cobra Disciples.” In 1980 the gang split in two that consisted of the YLO Cobras and YLO Disciples that still exist presently.
