Every year, huge bonfires are lit in areas across Northern Ireland on the Eleventh Night to usher in the main date in the parading calendar - the Twelfth of July.
The Twelfth is a day of commemorations, organised by loyal orders, marking the victory of Protestant King William of Orange over Catholic King James II at the Battle of the Boyne, north of Dublin, in 1690 - a triumph that secured a Protestant line of succession to the British Crown.
The Orange Order, which was founded in 1795, continues to champion William's legacy by espousing loyalty to the Crown and the Reformed faith.
