Martin McGuinness, an I.R.A. Leader Turned Peacemaker, Dies at 66

And on May 8, 2007, a day many thought would never come, the Rev. Ian Paisley, who had founded the Democratic Unionist Party and had long stood for continued Ulster association with Britain, and Mr. McGuinness, who had fought for Ulster’s incorporation into a united Ireland, took oaths as the leader and deputy leader, respectively, of Northern Ireland’s power-sharing government.
