Sinn Fein's O'Neill to Become First Northern Ireland First Minister From Irish Nationalist Party
• For the first time, a Sinn Fein politician, Michelle O'Neill, will serve as First Minister of Northern Ireland
• Sinn Fein was previously seen as the political wing of the IRA, but has pursued a political path since the 1998 Good Friday Agreement
• The First Minister role has always been held by a unionist politician before, but Sinn Fein believes Ireland should be a unified state
• On Saturday, the power-sharing government in Northern Ireland will revive after 2 years of political gridlock
• O'Neill becoming First Minister marks the first time someone who wants Northern Ireland out of the UK has held that role
