List of Scottish monarchs

The monarch of Scotland was the head of state of the Kingdom of Scotland. According to tradition, Kenneth I MacAlpin (Cináed mac Ailpín) was the founder and first King of the Kingdom of Scotland (although he never held the title historically, being King of the Picts instead). The Kingdom of the Picts just became known as the Kingdom of Alba in Scottish Gaelic, which later became known in Scots and English as Scotland; the terms are retained in both languages to this day. By the late 11th century at the very latest, Scottish kings were using the term rex Scottorum, or King of Scots, to refer to themselves in Latin.

The Kingdom of Scotland relinquished its sovereignty and independence when it unified with the Kingdom of England to form a single Kingdom of Great Britain in 1707. Thus, Queen Anne became the last monarch of the ancient kingdoms of Scotland and England and the first of Great Britain, although the kingdoms had shared a monarch since 1603 (see Union of the Crowns). Her uncle Charles II was the last monarch to be crowned in Scotland, at Scone in 1651. He had a second coronation in England ten years later.

The reign of Kenneth MacAlpin begins what is often called the House of Alpin, an entirely modern concept. The descendants of Kenneth MacAlpin were divided into two branches; the crown would alternate between the two, the death of a king from one branch often hastened by war or assassination by a pretender from the other. Malcolm II was the last king of the House of Alpin; in his reign, he successfully crushed all opposition to him and, having no sons, was able to pass the crown to his daughter's son, Duncan I, who inaugurated the House of Dunkeld.

*Eochiad was a son of Run, King of Strathclyde, but his mother was a daughter of Kenneth I. Evidence of his reign is unclear. He may have never actually been king and if he was, he was co-king with Giric.

¤Amlaíb is known only by a reference to his death in 977, which reports him as King of Alba; since Kenneth II is known to have still been King in 972–973, Amlaíb must have taken power between 973 and 977.

Duncan succeeded to the throne as the maternal grandson of Malcolm II. The House of Dunkeld was therefore closely related to the House of Alpin. Duncan was killed in battle by Macbeth, another maternal grandson of Malcolm II.

Macbeth came to power in 1040 after killing Duncan I in battle and had a long and relatively successful reign. Macbeth may have been a maternal grandson of Malcolm II and thus possibly a cousin of Duncan. He married Gruoch in 1032, who may have had a claim to the Scottish throne herself, being the granddaughter of either Kenneth II or Kenneth III. In a series of battles between 1057 and 1058, Duncan's son Malcolm III defeated and killed Macbeth and Macbeth's stepson and heir Lulach and became the king, thereby passing the throne back to the House of Dunkeld.

In a series of battles between 1057 and 1058, Duncan's son Malcolm III defeated and killed Macbeth and Macbeth's stepson and heir Lulach, claiming the throne. The dynastic feuds did not end there: on Malcolm III's death in battle, his brother Donald III, known as "Bán", claimed the throne, expelling Malcolm III's sons from Scotland. A civil war in the family ensued, with Donald III (later supported by Malcolm III's son Edmund) opposed by Malcolm III's other sons, led first by Duncan II and then by Edgar and backed by the Kingdom of England. Edgar triumphed, sending his uncle and brother to monasteries. After the reign of David I, the Scottish throne was passed according to rules of primogeniture, moving from father to son, or where not possible, brother to brother. Alexander III was the last ruler from the house of Dunkeld, and having no sons, the throne was inherited by his granddaughter Margaret, Maid of Norway.
