The formation of the Burgundian Empire by the four Valois Dukes of Burgundy would not have happened without the formidable royal and aristocratic women in their lives. These women, the wives, daughters, nieces, granddaughters and great-granddaughters, were vigorously engaged in the administration of the Burgundian empire, acting as governors and regents, making appointments, securing and making strategic marriages, raising taxes, negotiating treaties, engaging in cultural, religious and political patronage, giving birth to heirs and aiding in the military endeavours of their husbands. The history of these women involves numerous countries in Europe, including England, Scotland, France, Brittany, the Low Countries, Italy, Spain, the Holy Roman Empire, and many others.
