The Third Succession Act (35 Hen. 8. c. 1) was an act passed by the Parliament of England during King Henry VIII's reign that returned his daughters Mary and Elizabeth to the line of the succession behind their half-brother Edward. Born in 1537, Edward was the son of Henry VIII and his third wife, Jane Seymour, and heir apparent to the throne.
