Battle of The Boyne - Commemoration of The Battle

Commemoration of The Battle

Originally, Irish Protestants commemorated the Battle of Aughrim on 12 July (old style, equivalent to 23 July new style), symbolising their victory in the Williamite war in Ireland. At Aughrim, which took place a year after the Boyne, the Jacobite army was destroyed, deciding the war in the Williamites' favour. The Boyne, which in the old Julian calendar, took place on 1 July, was treated as less important, third after Aughrim and the anniversary of the Irish Rebellion of 1641 on 23 October. What was celebrated on "The Twelfth" was not William's "victory over Popery at the Battle of the Boyne", but the extermination of the elite of the Catholic Irish at Aughrim, thereby ending the fear of having to surrender the planted lands.

In 1752, the Gregorian calendar was adopted in Ireland, which erroneously placed the Boyne on 12 July instead of Aughrim (the correct equivalent date was 11 July, as the difference between the calendars for the year in question, 1690, was not 11 days but only 10 days). However, even after this date, "The Twelfth" still commemorated Aughrim. But after the Orange Order was founded in 1795 amid sectarian violence in Armagh, the focus of parades on 12 July switched to the Battle of the Boyne. Usually the dates before the introduction of the calendar on 14 September 1752 are mapped in English language histories directly onto the Julian dates without shifting them by 10 or 11 days. Being suspicious of anything with Papist connotations, however, rather than shift the anniversary of the Boyne to the new 1 July or celebrate the new anniversary of Aughrim, the Orangemen continued to march on 12 July which was (erroneously) thought to have marked the battle of the Boyne in New Style dates. Despite this, there are also smaller parades and demonstrations on 1 July, the date which maps the old style date of the Boyne to the new style in the usual manner and which also commemorate the heavy losses of the 36th (Ulster) Division on the first day of the Battle of the Somme in July 1916.

The memory of the battle also has resonance among Irish nationalists. Most Irish people see the battle as a major step on the road to the complete British colonisation of Ireland. In 1923, IRA members blew up a large monument to the battle on the battlefield site on the Boyne and destroyed a statue of William III in 1929 that stood outside Trinity College, Dublin in the centre of the Irish capital.
