The overall plot that would serve as the basis for
Macbeth is first seen in the writings of two chroniclers of Scottish history:
John of Fordun, whose prose
Chronica Gentis Scotorum was begun about 1363, and
Andrew of Wyntoun's Scots verse
Orygynale Cronykil of Scotland, written no earlier than 1420. ''
Holinshed's Chronicles (1587), drew on their accounts, and Shakespeare in turn used Holinshed’s narratives of King Duff and King Duncan when writing Macbeth''. Historically, Duff was a 10th century King of Alba. In John of Fordun's work, the reign of Duff is portrayed as having suffered from pervasive witchcraft. The Orygynale Cronykil suggests that Duff was murdered. Due to the Irish use of
tanistry, Duff's immediate descendants did not become rulers of Alba, and instead became
mormaers of
Fife. Their clan – the
Clan MacDuff – remained the most powerful family in Fife in the
Middle Ages. The ruins of
Macduff's Castle lie in the village of
East Wemyss next to the cemetery. Not only did history influence Shakespeare's work, but the work itself influenced the role of future Duffs. Few could determine where Duff Family history began and historical fiction ended, working to the benefit of the Duffs as their reach expanded into Northeast Scotland. In 1404 David Duff received a charter in Aberdeenshire from
Robert III of Scotland. In 1759, his descendant
William Duff was granted the historic Celtic Title of "Fife", resurrecting the title and tying the Duffs of Northeast Scotland, both to their 11th century Lowland ancestors, and to Shakespeare's MacDuff. Various Fife titles were held by the Duffs until as recently as 1929 when the dignity passed to the Carnegie descendants, where it remains in use today. This association not only secured the Duff family influence in the peerage, but also helped ensure their position as one of the largest landowners in Scotland, heading countless
feudal baronies including the
barony of MacDuff, named for
James Duff, 2nd Earl Fife. In Holinshed's narrative, attributes of King Duff are transposed onto the MacDuff mormaer from Macbeth's era. Macduff first appears in Holinshed's narrative of King Duncan after Macbeth has killed the latter and reigned as King of Scotland for 10 years. When Macbeth calls upon his nobles to contribute to the construction of
Dunsinane castle, Macduff avoids the summons, arousing Macbeth's suspicions. Macduff leaves Scotland for England to prod Duncan's son,
Malcolm III of Scotland, into taking the Scottish throne by force. Meanwhile, Macbeth murders Macduff's family. Malcolm, Macduff, and the English forces march on Macbeth, and Macduff kills him. Shakespeare follows Holinshed's account of Macduff closely, with his only deviations being Macduff's discovery of Duncan's body in act 2 sc. 3, and Macduff's brief conference with Ross in act 2 sc. 4. ==Role in the play==
