The Young Lords were saturated targets of the NYPD's Bureau of Special Services and the FBI — the Handschu litigation and later-released files documented undercover officers in the leadership's orbit from 1969 onward, and COINTELPRO-style operations tracked the group as it opened branches in Puerto Rico itself. Members faced continual arrest; supporters counted cases like the Lords defendants swept up around the 1971 armed actions and the surveillance-driven prosecutions of the mid-1970s among the era's political prisoners.
Renamed the Puerto Rican Revolutionary Workers Organization in 1972, the group turned toward party-building, was wracked by the factionalism its infiltrators fed, and dissolved by 1976. Its veterans — Juan González, Pablo Guzmán, Iris Morales, Denise Oliver — carried its legacy into journalism, law, medicine, and the movements that freed the FALN prisoners a generation later.
