King Henry VIII married his fourth wife, Anne of Cleves, after his previous wife died during childbirth.
Henry VIII was notorious for a lot of things, and at least six of them were his wives: Catherine Parr, Catherine Howard, Anne of Cleves, Jane Seymour, Anne Boleyn, and Catherine of Aragon. Henry infamously had Anne Boleyn and Catherine Howard executed, Jane Seymour died after childbirth, Catherine Parr outlived him, and he divorced Catherine of Aragon and Anne of Cleves.
Anne of Cleves was the fourth wife, and she was the one married to Henry for the shortest amount of time — the pair were married for only six months.
