In this encounter at Westminster in 1511, Henry VIII jousts before Catherine of Aragon to celebrate the birth of their son Henry. The young prince died ten days later. Though kings usually did well in tournaments, accidents were possible. Henry himself had a narrow escape in March 1524 when jousting with his visor open, and in 1559 Henry II of France was killed in a tournament when his opponent's lance splintered. foreign affairs remained something of a family matter right up until 1918.
