Marie de Coucy
Alexander II died on 8 July 1249 during an expedition against the Lord of Argyll on the island of Kerrera. Immediately after the news reached her, Marie made sure her 8-year-old son was crowned as soon as possible at Scone. Although her son was a minor and was placed under regency, Marie did not become regent. On 9 June 1250 Marie and her son Alexander III were present in Dunfermline for the observance of the canonisation of Saint Margaret of Scotland and the transference of her remains to the new shrine.
Expansion of Macedonia under Philip II
Alexander's 10-year campaign in Asia, and the Macedonian conquest of the Persian empire, were to become the stuff of legend. The Macedonian army campaigned in Asia Minor, the Levant, Egypt, Assyria, Babylonia and Persia, winning notable battles at the Granicus, the Issus and Gaugamela, before the final collapse of Darius's rule in 330 BC. Alexander thus became ruler of the extensive Persian domains, although his rule over most of the territory was far from secure. Alexander continued campaigning in central Asia in the following years, before crossing into the Indian sub-continent. However, the Macedonian army became increasingly unhappy, and eventually mutinied, forcing Alexander to turn back. Alexander spent his final years attempting to consolidate his empire and planning future campaigns but, probably exhausted by years of hard campaigning, he died in Babylon in 323 BC.
