White nigger

White nigger is a racially charged term, with somewhat different meanings in different parts of the English-speaking world.

White nigger was a derogatory and offensive term, dating from the nineteenth century, for a black person who deferred to white people or a white person who did menial work. It was later used as a slur against white activists involved in the civil rights movement such as James Groppi of Milwaukee.

The term "white niggers" was uttered twice by Senator Robert Byrd of West Virginia in an interview on national television in 2001.

In another use of the term, Pierre Vallières's work White Niggers of America refers to French Canadians.

The White Nigger was a nickname given to the nineteenth-century English explorer Richard Burton by colleagues in the East India Company Army.

"White nigger" was a religious and ethnic slur used to refer to Irish Catholics, in the context of The Troubles in Northern Ireland. An example of this can be found in the Elvis Costello song "Oliver's Army", which contains the lyric: "Only takes one itchy trigger. One more widow, one less white nigger."

In May 2016, Gerry Adams, the Leader of Sinn Féin, was criticised after writing on Twitter account "Watching Django Unchained - A Ballymurphy Nigger!" Ballymurphy is an area of Belfast best known for an eponymous massacre. Adams deleted the comment, and subsequently wrote "[Anyone] who saw Django would know my tweets & N-word were ironic. Nationalists in [the North] were treated like African Americans."
