      Lesson details

      Learning outcome

      I can explain the impact that World War One had on life both in Britain and in the colonies of the British Empire.

      Key learning points

      1. The estimated four million British men who fought in for Britain fought mostly in trenches, with huge losses of life.
      2. The war revolutionised life in Britain, particularly with women entering the workforce.
      3. The war slowed Ireland's journey towards independence from Britain, which would result in partition.
      4. The British army were supported by around three million soldiers from the British empire and former colonies.

      Keywords

      • Total war - a conflict in which the countries involved are willing to make any sacrifices to achieve victory

      • Empire - an empire is a group of countries or provinces ruled from the country by one person or a group of people

      • Colonial - relating to a country or area under the control of another country and occupied by settlers from that country

      • Home Rule - Home Rule is when a country is given some independence, usually in the form of their own government

      Common misconception

      The impact of WWI was limited to Europe, and those directly affected by the deaths of troops.

      The impact of WWI can be seen in Britain across different groups in society, but also within British colonies across the world.

      Teacher tip

      In delivering the explanation on the impact of the war at home, you can emphasise that different groups were impacted in very different ways! There were even differences within some groups, for example wealthy women saw immediate change after the war
