Henry III's policies towards Jews began with relative tolerance, but became gradually more restrictive. In 1253 the Statute of Jewry, reinforced physical segregation and demanded a previously notional requirement to wear square white badges. Henry III also backed an accusation of child murder in Lincoln, ordering a Jew Copin to be executed and 91 Jews to be arrested for trial; 18 were killed. Popular superstitious fears were fuelled, and Catholic theological hostility combined with Baronial abuse of loan arrangements, resulting in Simon de Montfort's supporters targeting of Jewish communities in their revolt. This hostility, violence and controversy was the background to the increasingly oppressive measures that followed under Edward I.
