Arthur Tudor
Although Elizabeth seems to have played little part in politics, her marriage appears to have been a successful and happy one. Her eldest son Arthur, Prince of Wales, died at age 15 in 1502, and three other children died young. Her second, and only surviving, son became King Henry VIII of England, while her daughters Mary and Margaret became queens of France and of Scotland, respectively; many modern royals, including Elizabeth II, trace their line through Margaret.
