Every year, many people turn out across Northern Ireland on July 12th to march and hold celebrations. But what is the commemoration all about?
The Twelfth marks the victory of King William of Orange over King James II at the Battle of the Boyne, which took place outside Drogheda in 1690. This struggle secured a Protestant line of succession to the British Crown.
The Orange Order, which was founded in 1795, celebrates William's legacy each year by parading through Northern Irish streets with a marching band.
