      Lesson details

      Learning outcome

      I can describe how the Vikings took over more and more of Britain in the 800s CE.

      Key learning points

      1. Viking raids increased in number throughout the 800s CE, and by 850 they had begun to make winter camps in Britain.
      2. In 865 CE, the biggest Viking army ever to have come to Britain arrived in East Anglia: The Great Heathen Army.
      3. By 869, the Vikings had won key battles against Northumbria and East Anglia while Mercia had bribed them not to attack.
      4. Only Wessex, which controlled most of southern Britain, remained in resistance to the Vikings.

      Keywords

      • Heathen - a heathen is a person who does not belong to a widely held religion

      • East Anglia - East Anglia was an Anglo-Saxon kingdom in the east of England

      • Northumbria - Northumbria was an Anglo-Saxon kingdom in northeastern England

      • Mercia - Mercia was an Anglo-Saxon kingdom in what is the Midlands in England today

      • Wessex - Wessex was an Anglo-Saxon kingdom in the south of England

      Common misconception

      Pupils may not understand that Britain was formed of separate Anglo-Saxon kingdoms.

      At this time, Britain was formed of four separate kingdoms: East Anglia, Northumbria, Mercia and Wessex.

      Teacher tip

      Emphasise to the pupils the skill of the Great Heathen Army in capturing large areas of Britain.
