In short
On July 12, 1690, Protestant King William III defeated Catholic King James II at the River Boyne in Ireland, securing William's claim to the English, Scottish, and Irish thrones. The battle lasted a single day but determined the religious and political character of Ireland for centuries, establishing Protestant dominance and triggering the final collapse of James's bid to reclaim power.
How it unfolded.
The five-minute version
What actually happened.
The Battle of the Boyne took place in 1690 between the forces of the deposed King James II, and those of King William III who, with his wife Queen Mary II, had acceded to the Crowns of England and Scotland in 1689. The battle was fought across the River Boyne close to the town of Drogheda in the Kingdom of Ireland, modern-day Ireland, and resulted in a victory for William. This turned the tide in James's failed attempt to regain the British crown and ultimately aided in ensuring the continued Protestant ascendancy in Ireland.
