Anne of Brittany, effectively the last Duchess of an independent Duchy of Brittany.
By the 15th century, France had been trying to incorporate Brittany into the kingdom for a while, while Anne's father, Duke Francis II, sought ways to stave off the French. It all depended upon Anne’s marriage. Francis sought to marry her to someone who could help preserve the Duchy’s independence, while the French crown sought a marriage that would aid French annexation of Brittany. Anne was engaged to Maximilian I, the Holy Roman Emperor, but Charles VIII, King of France, had the marriage annulled and married her himself in 1491, making him effectively Duke of Brittany.
Their marriage contract decreed that the spouse whom outlived the other would retain possession of Brittany, and, that were Charles VIII to die without a male heir, Anne would marry his successor, giving France a second chance at annexation.
During the marriage, Anne was forbidden to use the title “Duchess of Brittany,” and was forced to name Charles VIII her perpetual representative.
Due to their marriage contract, when Charles VIII died in 1498, she was forced to marry the new King of France, Louis XII. He was already married, so while waiting for a Papal annulment, Anne began to take charge of the administration of Brittany.
Her new marriage was radically different from her last. Louis XII formally recognized her right to the title “Duchess of Brittany” and issued decisions in her name. Also, she ensured that her second child would inherit the Duchy of Brittany, not her first (who would be heir to the French crown) ensuring the Duchy’s continued survival. This clause would not be respected in the future.
Anne arranged the marriage of her second child, Claude, heiress of the Duchy of Brittany, to Charles of Austria. Though the marriage contract was signed, her second husband, Louis XII, the French King, cancelled the engagement and had Claude married to the heir to the French Throne, Francis I. In an effort to keep the Breton Duchy independent, Anne refused to sanction the marriage until she lay on her death bed.
Anne died in 1514. Her will stated that the Duchy of Brittany was to be inherited by her second daughter, Renee. Louis XII ignored this, confirmed Claude as the new Duchess of Brittany and had her married to Francis I the next year.
Claude inherited the Duchy, and became Queen of France. In 1515 she gave the governance of her domains to her husband in perpetuity. She died in 1524, and the Duchy passed to her son, Francis III. He died quite young, and the Duchy passed to his brother, Henry, who became Henry II, King of France. Upon his coronation as King of France in 1547, the formerly independent Duchy of Brittany and the Kingdom of France were united as one.
