During what years was Macbeth King of Scotland?

Macbeth [d. August 15, 1057] was King of Scotland for 17 years, 1040-1057. He became King upon the death of King Duncan I [d. August 14, 1040]. He received mortal wounds, from the future King Malcolm III, in the battle of Lumphanan. He died a few days later in Scone, where he had been crowned 17 years earlier. He was succeeded by his stepson, Lulach mac Gille Coemgain [d. March 17, 1058], and then by King Duncan's son, King Malcolm III [d. November 13, 1093].
