Northern Ireland civil rights movement
The Northern Ireland civil rights movement dates to the early 1960s, when a number of initiatives emerged in Northern Ireland which challenged the inequality and discrimination against ethnic Irish Catholics that was perpetrated by the Ulster Protestant establishment (composed largely of Protestant Ulster loyalists and unionists). The Campaign for Social Justice (CSJ) was founded by Conn McCluskey and his wife, Patricia.
