      The rise of Alba under Constantine II

      Lesson details

      Learning outcome

      I can describe how Constantine II strengthened the kingdom of Alba.

      Key learning points

      1. With the Vikings defeated, Constantine now set about strenghtening his kingdom of Alba.
      2. He changed the Church to make it more like the one he had experienced in Ireland.
      3. He created a system of mormaers, local leaders who could help him rule over his lands.
      4. Eventually he came into conflict with a powerful king from England and they fought a big battle.
      5. Although Constantine lost, it stopped the king from England from taking control of parts of Scotland.

      Keywords

      • Church - the Church is the name given to a group of Christian people who share the same beliefs about their religion

      • Mormaer - a mormaer was a Scottish leader and landowner who helped the king to rule

      Common misconception

      Pupils may think that Athelstan controlled Scotland because he defeated Constantine.

      Although Constantine lost, Athelstan only remained king of England. He became overlord of Scotland but failed to unite England and Scotland under one kingship.

      Teacher tip

      Briefly look into a timeline of King Athelstan to understand his importance.
