Anne of Brittany in the context of List of French royal consorts

The union of the Duchy of Brittany with the Crown of France was the culmination of a political process begun at the end of the 15th century in the wake of the Mad War. It resulted in the Edict of Union of 13 August 1532 and the incorporation of the duchy into the Crown lands of France, a critical step in the formation of modern-day France.

As a territorial principality of the Kingdom of France, Brittany had enjoyed varying degrees of autonomy since Clovis I was given authority over the Gallo-Roman domain during the 5th century. It was first recorded as a "duchy" during the rule of Nominoe in 846, in likely recognition of Carolingian overlordship. Over the centuries, the fealty demonstrated by the Duchy of Brittany toward the French king depended significantly on the individuals holding the two titles, as well as the involvement of the English monarchy at that particular time. The reign of Francis II, Duke of Brittany, was at an especially crucial time, as the nobles struggled to maintain their autonomy against the increasing central authority desired by Louis XI. As a result of several wars, treaties, and papal decisions, Brittany was united with France through the eventual marriage of Louis XI's son Charles VIII to the heiress of Brittany, Anne in 1491. However, because of the different systems of inheritance between the two realms, the crown and the duchy were not held by the same hereditary claimant until the reign of Henry II, beginning 1547.

Charles VIII, called the Affable (French: l'Affable; 30 June 1470 – 7 April 1498), was King of France from 1483 to his death in 1498. He succeeded his father Louis XI at the age of 13. His elder sister Anne acted as regent jointly with her husband Peter II, Duke of Bourbon until 1491, when the young king turned 21 years of age. During Anne's regency, the great lords rebelled against royal centralisation efforts in a conflict known as the Mad War (1485–1488), which resulted in a victory for the royal government.

In a remarkable stroke of audacity, Charles married Anne of Brittany in 1491 after she had already been married by proxy to the Habsburg Holy Roman Emperor Maximilian I in a ceremony of questionable validity. Preoccupied by the problematic succession in the Kingdom of Hungary, Maximilian failed to press his claim. Upon his marriage, Charles became administrator of Brittany and established a personal union that enabled France to avoid total encirclement by Habsburg territories.

The Grandes Heures of Anne of Brittany (Les Grandes Heures d'Anne de Bretagne in French) is a book of hours, commissioned by Anne of Brittany, Queen of France to two kings in succession, and illuminated in Tours or perhaps Paris by Jean Bourdichon between 1503 and 1508. It has been described by John Harthan as "one of the most magnificent Books of Hours ever made", and is now in the Bibliothèque nationale de France, catalogued as Ms lat. 9474. It has 49 full-page miniatures in a Renaissance style, and more than 300 pages have large borders illustrated with a careful depiction of, usually, a single species of plant.

The bomb attack of 7 August 1932 in Rennes was aimed at a work by the sculptor Jean Boucher, symbolizing the union of Brittany and France, and placed in a niche in Rennes City Hall. Since its inauguration in 1911, the statue, representing Anne of Brittany, had been considered degrading by the Breton movement, due to its kneeling position before the King of France.

Its symbolic setting was the festivities marking the 400th anniversary of Brittany's union with France, which took place in Vannes on the same day. The first attack committed by the Breton movement, it was also the first action of the armed group Gwenn ha Du. It was carried out by Célestin Lainé, who supplied the bomb, and André Geffroy, who planted it.

Claude of France (13 October 1499 – 26 July 1524) was Queen of France from 1 January 1515 as the wife of King Francis I and Duchess of Brittany in her own right from 9 January 1514 until her death in 1524. She was the eldest daughter of King Louis XII of France and Duchess Anne of Brittany.
