The Weathermen emerged from the campus-based opposition to United States involvement in the Vietnam War and from the civil rights movement of the 1960s. One of the factors that contributed to the radicalization of SDS members was the Economic Research and Action Project that the SDS undertook in Northern urban neighborhoods from 1963 to 1968. This project was aimed at creating an interracial movement of the poor that would mobilize for full and fair employment or guaranteed annual income and political rights for poverty class Americans.
