Engrogne with crowned lion - Philip III

Philip III — "the Good" — inherited Burgundy in 1419 following the assassination of his father John the Fearless on the bridge at Montereau, a killing in which the French dauphin's men were directly implicated. That rupture pushed Philip into a formal alliance with the English, sealed at Troyes in 1420, which recognized Henry V as heir to the French crown. The billon coinage of his early reign circulated through a duchy that was, politically, effectively at war with its nominal French overlord.

The engrogne type takes its name from the Burgundian dialect word for the snarling or growling expression — a detail of the lion's rendering that contemporaries found distinctive enough to coin a name for it.
