Voltaire and the Calas affair

1762 · Event

Jean Calas, a Protestant merchant of Toulouse, is broken on the wheel for supposedly murdering a son who wanted to convert to Catholicism — a son who had in fact killed himself. Voltaire, convinced of the injustice, spends three years mobilising Europe with pamphlets and his Treatise on Toleration until the verdict is annulled and the family compensated: the Enlightenment's first great public-opinion campaign, fought under his war cry 'écrasez l'infâme'.
