Domestic tensions ran high at the start of the decade , with the Peterloo Massacre ( 1819 ) , the Cato Street Conspiracy ( 1820 ) , and the Radical War ( 1820 ) in Scotland . However , by the end of the 1820s , many repressive laws were repealed . In 1822 , Britain repealed the death penalty for over 100 crimes , and punishments such as drawing and quartering and flagellation fell out of use . Seditious Meetings Prevention Act ( barring large assemblies ) and the Combination Act ( banning trade unions ) were repealed in 1824 . The Catholic Relief Act by Parliament of the United Kingdom granted a substantial measure of Catholic Emancipation in Britain and Ireland
