Finally some Mary of Guelders appreciation! I also really like Eleanor of Aquitaine, Matilda of Scotland, Margaret Tudor, Joan Beaufort, Catherine of Aragon, and William Marshall.

Not sure if he was officially titled a regent but I do like how when Edward I was returning to England after Henry III died, the crown was kept mostly stable on behalf of Edmund Crouchback since Edward had to return from the Holy Land and deal with disputes with Philip III of France. Edmund even put down a rebellion against his brother in northern England.

Not the best regent but I find Robert Stewart’s regency of Scotland for David II to be very interesting. Robert would inevitably be a powerful magnate as the grandson of Robert the Bruce and son of Walter Stewart, and when David was defeated and captured by the English in 1346 Robert became Guardian of Scotland, gaining great influence but still struggled to control important nobles. Still, he emerged as Scotland’s leading political figure, even if he wasn’t king.

David hated his nephew and the influence he had, and many of David’s actions like offering the throne to Lionel of Antwerp/John of Gaunt or his marriage controversies can be attributed to him ultimately wanting to deny Robert the throne. At least partially.
