      Lesson details

      Learning outcome

      I can explain why Charles I was executed for treason.

      Key learning points

      1. After the First English Civil War, Parliament and the New Model Army began trusting each other less
      2. Charles encouraged Scotland to wage war with England, which was seen as a betrayal
      3. 'Pride's Purge' was when MPs who were sympathetic to the king were not allowed to enter Parliament
      4. 'Rump Parliament' put Charles I on trial for treason
      5. Charles was executed by beheading on 30 January 1649

      Keywords

      • Treason - treason is a serious crime which involves hurting your country or government

      • New Model Army - the New Model Army fought for the Parliamentarians, and against the Royalists, during the English Civil War

      • Regicide - regicide is the act of killing a monarch

      • Martyr - a martyr is a person who died for their beliefs and is respected because of that

      • Purge - getting rid of things you don’t agree with can be called a purge

      Common misconception

      Parliament fought both Civil Wars to remove Charles I from power

      The majority of people in Parliament wanted to change how Charles I behaved but only a minority wanted to remove the king from power.

      Teacher tip

      In learning cycle 3, you could begin by asking students if they think the source was just reporting events or acting as propaganda (trying to persuade). Ask students to identify details from the source which can justify their answer.
