James V of Scotland

Acceded as an infant after his father's death at Flodden and reigned through a turbulent minority dominated by competing factions of the Douglas family and his English uncle Henry VIII. Resisting Henry's pressure to break with Rome, he turned instead to France, marrying first Madeleine of Valois and then Marie de Guise. He died in despair after the catastrophic defeat at Solway Moss, his only surviving heir a six-day-old daughter — Mary, Queen of Scots.
