The European Royals Message Board: Re: Minor queens

Upon the death of François II, Duke of Brittany in 1488, his daughter Anne became Duchess Regnant of Brittany, Countess of Nantes, Montfort, and Richmond, and Viscountess of Limoges. She was only 11 at that time.

Although her date of birth is unknown Eleanor of Aquitaine became a sovereign Duchess of Aquitaine in her own right aged 12 to 15.

I know that there have been plenty of minor kings in royal history. Because succession laws have traditionally favored, if not been restricted to, males, there obviously have not been anywhere near as many queens regnant in history. That being said, England, Scotland, Spain, and Portugal have had their share.

So I got to wondering about the number of female monarchs who were minors at the times of accession. Off the top of my head, the following make the list --

Queen Margaret of Scotland (the so-called "Maid of Norway"), who succeeded her maternal grandfather (King Alexander III) as a child, for reasons that she was the only legitimate descendant of the royal house.

Mary Stuart, Queen of Scots, only surviving legitimate child of King James V: the princess was only a week old when her father died, but she was immediately proclaimed queen of Scotland

Queen Isabel II of Spain: she was only three years old when her father, King Fernando VII, died -- and her accession triggered the Carlist wars (those bastards seemed to have a hard time in remembering their history, as they conveniently forgot how the Bourbons even came to the Spanish throne in the first place -- via Infanta Maria Teresa)

Queen Maria II of Portugal: her reign was interrupted by her uncle Miguel, who usurped the throne (1828-1834), but she was a minor at her first accession, in 1826 -- when she was only seven years old.

Queen Christina of Sweden: she was only six years old when her father, King Gustavus Adolphus, died in battle.

Queen Wilhelmina of the Netherlands: she was only 10 years old when her father, King Willem III, died

Grand Duchess Marie Adelaide of Luxembourg was several months short of her 18th birthday, when in 1912 her father (Grand Duke Guillaume IV) died. So she was technically a minor, aged 17, at the time.

Are there any other examples? None of England's queens regnant was a minor at accession; and I don't believe Russia has had any minor empresses, either. What about earlier history? Or the kingdoms of Castile, Aragon, Leon, or Navarre?
