At the start of the fifteenth century, two dynastic inventories were compiled, prompted by the death of two key European rulers. The first came into being on the death of Philip the Bold, duke of Burgundy in 1404, the second on the death of his wife Margaret of Flanders, less than a year later in 1405. These two dynastic inventories, preserve references to thousands of moveable objects, but still remain underexplored by historians. This article will reassess these inventories in light of the ‘material turn’ to reconstruct the political ‘theatres’ and ‘actors’ involved in their construction. In addition, it will examine the objects of the inventories to reveal the ways in which they operated as agents of dynastic power, maintaining and creating networks of social relations at a critical political moment for the Burgundian dynasty.
