      Lesson details

      Learning outcome

      I can explain how the Romans invaded Britain during the reign of Emperor Claudius.

      Key learning points

      1. Emperor Claudius ordered the invasion of Britain in 43 CE to secure his position as emperor.
      2. The invasion was very successful due to the strengths of the Ancient Roman army.
      3. Ancient Roman legionaries were highly trained, well equipped and disciplined soldiers.
      4. The legionaries used superior tactics alongside fort building to defeat the British tribes.

      Keywords

      • Triumph - a triumph was a celebration in the streets of Rome when the emperor returned from winning a war

      • Invade - to go somewhere with an army to try to take over is to invade

      • Legionaries - legionaries were well-trained Ancient Roman soldiers

      • Tactics - plans an army uses to defeat their enemies are called tactics

      Common misconception

      Pupils may think that the people of Britain formed a united kingdom at this time.

      Remind pupils that 1st century CE Britain was made up of various Celtic people, kingdoms and tribes.

      Teacher tip

      When discussing Ancient Roman legionaries, compare them to other soldiers and warriors pupils have learnt about in previous units.
