 The involvement of a small percentage of recent immigrants in organized crime created a lasting stereotype of devious immigrants corrupting the morality of native-born Americans.Organized crime was a complex set of relations between the recently arrived Jewish and Italian criminals and groups like the Irish-American organized crime networks, which had been established before the 1920s and which the newer groups were sometimes subordinate to.Although never receiving close to the level of cultural attention of the Italian-American Mafia, from the late 1960s, Jewish-American gangsters would figure as characters in Jewish American literature.
