In the early to mid-1970s, Official Sinn Féin was sometimes called Sinn Féin (Gardiner Place) to distinguish it from the rival offshoot Provisional Sinn Féin, or Sinn Féin (Kevin Street).
In Northern Ireland, Sinn Féin was organised under the name Republican Clubs to avoid a ban on Sinn Féin candidates (introduced in 1964 under Northern Ireland's Emergency Powers Act), and the Officials continued to use this name after 1970 [REF].
