...Arras in 1435. These diplomatic gatherings laid essential groundwork for the reconciliation between Charles VII and Philip the Good, Duke of Burgundy, effectively shifting the balance of power in the protracted Hundred Years' War.

Arthur de Richemont, Constable of France, skillfully leveraged his extensive Burgundian connections to negotiate and finalize the Treaty of Arras, signed on September 21, 1435. This landmark agreement ended decades of bitter hostility stemming from the 1419 assassination of Philip’s father, John the Fearless, a crime in which Charles VII had been implicated. The treaty fundamentally altered the geopolitical landscape by severing Burgundy's longstanding alliance with England, consolidating Charles VII’s legitimacy, and isolating English ambitions in northern France. It marked a critical turning point—not only in the Hundred Years' War—but also in Richemont's distinguished political and military career, significantly elevating his status as a statesman and diplomat.
