At the dawn of the 1400s, the Duchy of Burgundy was ruled by Duke Philip II, given the duchy by he relative the king of France. With sea access allowed through Flanders, inherited through marriage in 1384, a new interest in naval affairs came to be. Philip II sponsored the construction of new merchant ships, and new warships to patrol Burgundian waters.
In response to Hesses tolerance of German pagans, Burgundy would join the hessian crusade in 1404, and as a reward, the Papacy would recognize Philip II as the heir to the duchies of Brabant and Limburg. Those territories would be inherited when Joanna of Brabant would pass away in 1406.
