July 12th marks the commemoration of the Battle of the Boyne, which transpired on July 1, 1690, along the River Boyne in close proximity to the Irish town of Drogheda. The alteration in dates stems from the transition from the Julian calendar to the Gregorian calendar.

This historic clash played a pivotal role in James's endeavor to reclaim the English and Scottish thrones, pitting Jacobite forces against William of Orange.
