The Gordon Riots

In 1780 London was devastated by terrible riots, instigated by Lord George Gordon against the Catholics.  More than 800 people died and much of the city was destroyed.  Fires broke out as Catholic chapels were attacked, the prisons were broken into and the prisoners released.  Lord George, an unstable Scottish peer, was arrested.  He converted to Judaism, and ended his days in Newgate as an orthodox Jew.
