The most remarkable event of Clement VIII's reign was the reconciliation to the Church of Henry IV of France (1589–1610), after long negotiations, carried on with great dexterity through Cardinal Arnaud d'Ossat, that resolved the complicated situation in France. Henry embraced Catholicism on 25 July 1593. After a pause to assess Henry IV's sincerity, Clement VIII braved Spanish displeasure, and in the autumn of 1595 he solemnly absolved Henry IV, thus putting an end to the thirty years' religious war in France.
