Malcolm is a character in William Shakespeare's "Macbeth" (c. 1603–1607).
 The character is based on the historical king Malcolm III of Scotland, and is derived largely from the account in "Holinshed's Chronicles" (1587), a history of Britain.
 He is the elder son of King Duncan, the heir to the throne, and brother to Donalbain.
 In the end, he regains the throne after mustering support to overthrow Macbeth.
King Duncan is a fictional character in Shakespeare's "Macbeth."
 He is the father of two youthful sons (Malcolm and Donalbain), and the victim of a well-plotted regicide in a power grab by his trusted captain Macbeth.
 The origin of the character lies in a narrative of the historical Donnchad mac Crinain, King of Scots, in Raphael Holinshed's 1587 "The Chronicles of England, Scotland, and Ireland," a history of Britain familiar to Shakespeare and his contemporaries.
 Unlike Holinshed's incompetent King Duncan (who is credited in the narrative with a "feeble and slothful administration"), Shakespeare's King Duncan is crafted as a sensitive, insightful, and generous father-figure whose murder grieves Scotland and is accounted the cause of turmoil in the natural world.
King Duncan is a character in William Shakespeare's play "Macbeth".
Donnchad mac Crinain (Modern Gaelic: "Donnchadh mac Crìonain"; anglicised as Duncan I, and nicknamed An t-Ilgarach, "the Diseased" or "the Sick"; ca. 1001 – 14 August 1040) was king of Scotland ("Alba") from 1034 to 1040.
 He is the historical basis of the "King Duncan" in Shakespeare's play "Macbeth".
Inverness ( ; from the Scottish Gaelic: "Inbhir Nis" ] , meaning "Mouth of the River Ness") is a city in the Scottish Highlands.
 It is the administrative centre for the Highland council area, and is regarded as the capital of the Highlands.
 Inverness lies near two important battle sites: the 11th-century battle of Blàr nam Fèinne against Norway which took place on The Aird and the 18th-century Battle of Culloden which took place on Culloden Moor.
 It is the northernmost city in the United Kingdom and lies within the Great Glen (Gleann Mòr) at its north-eastern extremity where the River Ness enters the Moray Firth.
 At the latest, a settlement was established by the 6th century with the first royal charter being granted by Dabíd mac Maíl Choluim (King David I) in the 12th century.
 The Gaelic king Mac Bethad Mac Findláich (MacBeth) whose 11th-century killing of King Duncan was immortalised in Shakespeare's largely fictionalized play "Macbeth", held a castle within the city where he ruled as Mormaer of Moray and Ross.
