The Battle of the Boyne (Irish: Cath na Bóinne) was a turning point in the Williamite claim on the English throne.
The deposed King James VII of Scotland and James II of England and Ireland and his Jacobite supporters were defeated by James' nephew and son-in-law, William III and his supporters. By the invitation of Parliament, William had deposed James in 1688. Both kings acted as commander of their respective armies.
The battle took place on July 1, 1690 (OS) just outside the town of Drogheda on Ireland's east coast. Each army stood on opposing sides of the River Boyne. William's forces easily defeated those of James who led an army of mostly raw recruits. The symbolic importance of this battle has made it one of the best-known battles in British and Irish history and a key part in Irish Protestant folklore. It is still commemorated today, principally by the Orange Institution. As a consequence of the adoption of the Gregorian calendar, the battle is now commemorated on July 12 each year.
