The Mormaer or Earl of Menteith was the ruler of the province of Menteith in the Middle Ages. The first mormaer is usually regarded as Gille Críst (or Gilchrist), simply because he is the earliest on record. The title was held in a continuous line from Gille Críst until Muireadhach IV (a.k.a. Murdoch Stewart, Duke of Albany), although the male line was broken on two occasions. A truncated version of the earldom was given two years later to Malise Graham, 1st Earl of Menteith, in compensation for loss of the Earldom of Strathearn, which was a likely result of the execution of the Duke of Albany.
