Malcolm II of Scotland in the context of "List of Kings of Leinster"

The House of Alpin, also known as the Alpinid dynasty, Clann Chináeda, and Clann Chinaeda meic Ailpín, was the kin-group which ruled in Pictland, possibly Dál Riata, and then the kingdom of Alba from Constantine II (Causantín mac Áeda) in the 940s until the death of Malcolm II (Máel Coluim mac Cináeda) in 1034.

Kings traced their descent from Kenneth MacAlpin (and not from his father, Alpín mac Echdach), and Irish genealogies in the Book of Ballymote and the Book of Lecan refer to the kindred as Clann Cináeda meic Ailpín by prioritising descent from Kenneth.

Findláech mac Ruaidrí (died 1020), son of Ruaidrí mac Donald, was the minor "king", locally called "Mormaer", of Moray, in the north of modern-day Scotland, from some point before 1014 until his death in 1020. Findláech's son Macbethad mac Findláech (Mac Bethad), was made famous as the protagonist of William Shakespeare's play Macbeth.

14th century Scottish chronicler and poet Andrew of Wyntoun claims that Findlaech fathered Mac Bethad with Malcolm II of Scotland's second daughter Donalda, as one of several dynastic marriages Malcolm II used to consolidate his own kingship, but there is no other confirmation of this.

The Battle of Carham was fought between the English ruler of Bamburgh and the king of Scotland in alliance with the Cumbrians. The encounter took place in the 1010s, most likely 1018 (or perhaps 1016), at Carham on Tweed in what is now Northumberland, England. Uhtred, son of Waltheof of Bamburgh (or his brother Eadwulf Cudel), fought the combined forces of Malcolm II of Scotland and Owen the Bald, king of the Cumbrians (or Strathclyde). The result of the battle was a victory for the Scots and Cumbrians.

Eadwulf Cudel or Cutel (meaning cuttlefish) (died early 1020s), sometimes numbered Eadwulf III, was ruler of Bamburgh for some period in the early eleventh century. Following the successful takeover of York by the Vikings in 866/7, southern Northumbria became part of the Danelaw, but in the north English rulers held on from a base at Bamburgh. They were variously described as kings, earls, princes or high-reeves, and their independence from the kings of England and Scotland is uncertain. Uhtred the Bold and Eadwulf Cudel were sons of Waltheof, ruler of Bamburgh, who died in 1006. He was succeeded by Uhtred, who was appointed by Æthelred the Unready as earl in York, with responsibility for the whole of Northumbria. Uhtred was murdered in 1016, and king Cnut then appointed Erik, son of Hakon, earl at York, while Eadwulf succeeded at Bamburgh.

In 1018, the Northumbrians of Bamburgh were defeated by Malcolm II of Scotland in the Battle of Carham. In one twelfth-century Durham source, De obsessione Dunelmi, Ealdulf is described as "a very lazy and cowardly man", who ceded Lothian, the northern part of Bernicia, to the Scots—though the historicity of this claim is disputed, one of several twelfth-century English accounts that try to explain the 'loss' of Lothian to Scotland. Another twelfth-century tradition relates that Lothian had been under Scottish control since the time that King Edgar ceded it to Kenneth II of Scotland in the early 970s. Recently, it has been argued that Lothian remained part of the principality of Bamburgh until its dissolution around 1090, during the reign of Malcolm III.
