The fourteen interviews of the NYPD Guardians oral history collection document the history of the fraternal organization and the experiences of members as police officers in New York City. The New York Police Department Guardians Association was founded in 1943 and recognized by the NYPD as a fraternal organization in 1949. Over the years it has served African American officers and civilian employees of the NYPD by developing community; providing education and mentorship; advocating within the department; and taking legal action to combat discrimination in hiring and promotion. The narrators discuss the impact of the Guardians on officers' careers, the group's advocacy against discrimination in the NYPD, and developments in police work from the 1960s-2010s.
