The Duchy of Brittany was a historical region in northwestern France, known for its distinct culture and language. Established in the 9th century, it became an important political entity, often asserting its independence from the French crown. The duchy was ruled by a series of dukes, who played a significant role in the region's development and its relations with neighboring territories. In 1532, the Duchy of Brittany was officially united with the Kingdom of France, although it retained some degree of autonomy for a time. The region is famous for its rich history, beautiful landscapes, and unique traditions, which continue to influence Brittany today.
