King Alexander II 
- Marriage: Marie DE COURCEY 
- Died: 1249
Alexander was the only son of William the Lion and his wife Ermengarde. Born at Haddington, East Lothian on 24 August 1198, he was knighted by King John of England on 4 March 1212. Two years later, he succeeded his father. Although Alexander backed the barons who forced John to sign the Magna Carta, in 1221 he married John's eldest daughter Joan in York. She had no children, and died in 1238. The following year at Roxburgh, he married Marie, daughter of Enguerand, Baron de Coucy in Picardy - an alliance which raised English fears of a Franco-Scottish alliance. The long-standing dispute between Scotland and England over the Border was settled in 1237 when, by the Treaty of York, Alexander renounced Scotland's claims to the three northern counties of England in exchange for the honour of Tynedale and the manor of Penrith. The border between Scotland and England was now fixed almost exactly on its present line from the lower Tweed in the east to the Solway Firth in the west. Alexander died on the island of Kerrera, Argyllshire in 1249 whilst preparing to take the Hebrides from Norway. He was buried at Melrose Abbey, Roxburghshire. Alexander II (1214-1249)
king of Scotland from 1214 to 1249; he maintained peace with England and greatly strengthened the Scottish monarchy.
Alexander came to the throne on the death of his father, William I the Lion (reigned 1165-1214). When the English barons rebelled against King John (reigned 1199-1216) in 1215, Alexander sided with the insurgents in the hope of regaining territory he claimed in northern England. After the rebellion collapsed in 1217, he did homage to King Henry III (reigned 1216-72), and in 1221 he married Henry's sister, Joan (d. 1238). In 1237 Henry and Alexander concluded an agreement (Peace of York) by which the Scots king abandoned his claim to land in England but received in exchange several English estates. The boundary of Scotland was fixed approximately at its present location.
Meanwhile, Alexander was suppressing rebellious Scots lords and consolidating his rule over parts of Scotland that had hitherto only nominally acknowledged royal authority. In 1222 he subjugated Argyll. He died as he was preparing to conquer the Norwegian-held islands along Scotland's west coast.
