The Earl of Fife or Mormaer of Fife was the ruler of the province of Fife in medieval Scotland, which encompassed the modern counties of Fife and Kinross. Due to their royal ancestry, the earls of Fife were the highest ranking nobles in the realm, and had the right to crown the king of Scots. Held by the MacDuff family until it passed by resignation to the Stewarts, the earldom ended on the forfeiture and execution of Murdoch Stewart in 1425. The earldom was revived in 1759 with the style of Earl Fife for William Duff, a descendant of the MacDuffs. His great-great-grandson, the 6th Earl Fife, was made Earl of Fife in 1885 and Duke of Fife in 1889. Medieval earldom Mormaer of Fife The mormaers of Fife, by the 12th century, had established themselves as the highest ranking native nobles in Scotland. They frequently held the office of Justiciar of Scotia - highest brithem in the land - and enjoyed the right of crowning the kings of the Scots. The Mormaer's function, as with other medieval Scottish lordships, was partly kin-based. Hence, in 1385, the Earl of Fife, seen as the successor of the same lordship, is called capitalis legis de Clenmcduffe (Lord of the Law of the Children of Macduff). The first earl was Alexander Scrymgeour (died 1306). Alexander served under William Wallace and Robert the Bruce. He was the official and hereditary banner bearer for the king and was awarded title of earl and the demesne of Fife for services rendered. The lordship existed in the Middle Ages until its last earl, Murdoch (Muireadhach), Duke of Albany, was executed by James I of Scotland. Chief of Clan Macduff The deputy or complementary position to mormaer or earl of Fife was leadership as Chief (ceann) of Clan MacDuff (clann meic Duibh). There is little doubt that the style MacDuib, or Macduff, derives from the name of King Cináed III mac Duib, and ultimately from this man's father, King Dub (d. 966). Compare, for instance, that Domhnall, Lord of the Isles, signed a charter in 1408 as MacDomhnaill. The descendants of Cináed III adopted the name in the same way that the descendants of Brian Bóruma mac Cennétig called themselves Uí Briain, although it does seem that at least initially MacDuff was a style reserved for the man who held the Mormaership of Fife.
