The Battle of Lumphanan was fought on 15 August 1057, between Macbeth, King of Scots, and the future King Malcolm III. Macbeth would die from wounds sustained in the battle, which came after his defeat at the battle of Dunsinane in 1054. According to tradition, the battle took place at Lumphanan in Aberdeenshire. Macbeth's Stone, a large boulder at the site, is said to mark the spot where Macbeth was mortally wounded. Following the battle, Lulach - Macbeth's stepson - was crowned King, before being killed by Malcolm who then took the throne.
Background
Since the death of his father, King Duncan, in battle with Macbeth, Malcolm had been sheltered by Earl Siward of Northumbria, his uncle. It was with Siward's backing that Malcolm first attacked Macbeth leading to the battle of Dunsinane in 1054, where Malcolm failed to win the crown, but had his own lands restored to him. in modern day Aberdeenshire. The battle itself appears to have been a comparatively minor affair, except for Macbeth being mortally wounded and later dying.
