Lord Protector is the title assumed by a noble after he marries the female ruler of a castle or region.
Known Lords Protector
- Petyr Baelish marries the widow Lysa Arryn, Lady Regent of the Vale. Pycelle notes that their marriage would make him "acting Lord" of the Vale.
- Tyrion Lannister, through his marriage to Sansa Stark, considered Lady of Winterfell as her brothers Bran and Rickon are believed dead. His duties, however, are carried out by Roose Bolton, who has been named Warden of the North, with the intent of Tyrion assuming direct control in the near-future. Joffrey's assassination, Tyrion's subsequent false imprisonment, and Sansa's escape from King's Landing mean that ultimately Tyrion was never really able to exert any control on the North through her as Lord Protector, even briefly.
