In his attempts to conquer Scotland, Edward I of England invaded in 1296 at the head of an army. Sacking Berwick, beating the Scots at Dunbar, and laying siege to Edinburgh Castle, Edward then proceeded to Scone, intending to take the Stone of Destiny, which was kept at Scone Abbey. He had already taken the Scottish regalia from Edinburgh, which included Saint Margaret's Black Rood relic, but to confiscate an object so precious to the Scots, and so symbolic of their independence, would be a final humiliation. He carried it back to Westminster Abbey. By placing it within the throne of England, he had a potent symbol of his claim for overlordship. It is this stone which sat in Westminster until 1996, when it was returned to Scotland.
