Why was Tudor era called Tudor era?

Answer The Welshman Henry Tudwr gained the throne of England after defeating and killing Richard Plantagenet (Richard III) at the Battle of Bosworth. The English spelling of Tudor was adopted for the name of his family. The Tudor period in English History is named after the monarchs who belonged to the Royal House of Tudor - almost, but not quite the same as a surname as we would understand it today. The Tudor monarchs were: Henry VII Henry VIII, son of Henry VII Edward VI, son of Henry VIII Lady Jane Grey, grand daughter of Henry VII Mary I, daughter of Henry VIII Elizabeth I, daughter of Henry VIII.
