King Alexander III came to the Scottish throne in 1249, at the age of just 7 years, following the death of his father, Alexander II.
The early years of Alexander III’s reign were dominated by a power struggle between two factions who had their own designs on his kingdom. However, when he reached the age of 21 and was able to rule in his own right, Alexander showed his strength as king by continuing his father’s aspirations of gaining control of the Western Isles, which until then had been under the domination of Norway.
A wealthy nation
Alexander went on to preside over a Scotland which was a wealthy nation in its own right within northern Europe. Roads, bridges and other infrastructure were built and people in general had good standards of living. But all this good work and the Scotland’s stability were undone due to an unfortunate series of events.
He had married Margaret of England, daughter of Henry III, at the age of ten, and eventually they had three children together. All three of these children were to die before Alexander III, the two sons before they could father any children and his daughter, who was married into the Norwegian royal family, died in childbirth, leaving Alexander with only a granddaughter as an heir.
Isabel was born on February 21, 1397 in Evora. Her father was King John I of Portugal of the house of Aviz. Her mother was Philippa of Lancaster, the daughter of John of Gaunt, Duke of Lancaster and granddaughter of King Edward III of England. Isabel’s father had become king with the help of John of Gaunt and cemented his alliance and friendship with Gaunt and England by marrying Philippa. Isabel was to value friendship with England all her life.
