The monarch of Scotland was the head of state of the Kingdom of Scotland. According to the Annals of Ulster, Kenneth I MacAlpin () — styled King of the Picts — was the first king of a unified kingdom that encompassed the majority of what would later become the Kingdom of Alba. The Kingdom of the Picts went through a series of political turmoils including Viking invasions, and the assassination of Áed, King of The Picts in 878CE. The Kingdom of Alba became the kingdom's official name during the reign of Domnall mac Causantín, further evolving into the "Kingdom Of Scotland" in Scots and English by the 11th Century. Scottish kings would eventually style themselves using the term "", or King of Scots.

After years of being ruled in a personal union, both the kingdoms of Scotland and England were dissolved to form a single unified kingdom, the Kingdom of Great Britain, in 1707. Queen Anne was the last monarch of both the kingdoms of Scotland and England and the first of Great Britain (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.

Heraldry

List of monarchs of Scotland House of Alpin (848–1034)

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.

The name never came into wider use in the Scottish world, or the Gaelic world more generally, and has no modern form.

*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.

House of Dunkeld (1034–1040)

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.

House of Moray (1040–1058)

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.

House of Dunkeld (restored) (1058–1286)

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.

House of Sverre (1286–1290)

Margaret, Maid of Norway inherited the throne in 1286, but died in 1290 in Orkney on her way to be crowned. During her absence, Scotland was ruled by a set of guardians. After her death, Scotland entered a period of interregnum, where 13 contenders fought for the throne and ultimately, John Balliol succeeded.

The status of Margaret, as a Scottish monarch is debated by historians. She was never crowned, and her contemporaries in Scotland described her as "queen" very rarely, referring to her instead as Scotland's "lady", "heir", or "lady and heir". On the other hand, documents issued from late 1286 no longer refer to the "king whosoever he may be", indicating that the throne may have been regarded as already occupied by Margaret. In modern historiography she is nearly unanimously called "queen", and reference books give 19 March 1286, the date of Alexander III's death, as the start of her reign.

First Interregnum (1286–1292)

The First Interregnum began upon the death of Alexander III of Scotland in 1286. Alexander's only surviving descendant was his granddaughter Margaret, Maid of Norway, a young child, who inherited the throne in 1286. A set of guardians were appointed to rule Scotland in her absence since she was living in Norway where her father Eric II was king. She was finally sent to Scotland in 1290 but died before arriving in Scotland. The next king of Scots was not determined until completion of an arbitration in 1292.

House of Balliol (1292–1296)

The death of Margaret of Norway began a two-year interregnum in Scotland caused by a succession crisis. With her death, the descent of William I became extinct and there was no obvious heir. Thirteen candidates presented themselves; the most prominent were John Balliol, great-grandson of William I's younger brother David of Huntingdon, and Robert de Brus, 5th Lord of Annandale, grandson of David of Huntingdon. The Scottish magnates invited Edward I of England to arbitrate the claims. He did so but forced the Scots to swear allegiance to him as their overlord. Eventually, it was decided that John Balliol should become king. He proved weak and incapable and, in 1296, was forced to abdicate by Edward I. Edward then attempted to annex Scotland into the Kingdom of England.

Second Interregnum (1296–1306)

John Balliol abdicated in March 1296. That same month Edward I invaded Scotland. The second set of guardians were appointed under Edward I who ruled from 1296 to 1306, until the election of Robert the Bruce as the king of Scotland.
