The Congress of Arras was a diplomatic assembly held in the town of Arras in 1435. It brought together negotiators representing England, France and the Duchy of Burgundy during the later stages of the Hundred Years' War. Intended as a forum to explore a negotiated settlement, the talks produced the Treaty of Arras, a separate agreement between Duke Philip the Good and King Charles VII of France that changed the balance of alliances.

Background and purpose

By the 1430s the military situation in France had shifted in favour of Charles VII: royal authority had been recovering after years of civil conflict and foreign occupation. England maintained significant holdings on the continent and relied on support from Burgundy. The congress was convened to discuss peace and territorial questions, but negotiations were affected by long-standing grievances, the recent murder of John the Fearless (Duke of Burgundy) in 1419, and changing political calculations in Burgundy and Paris.

Negotiations and the Treaty

Delegations exchanged proposals over several weeks. Rather than achieving a comprehensive tripartite agreement, the gathering resulted in a bilateral reconciliation: Philip the Good concluded terms with Charles VII. That settlement pacified Burgundian claims and restored formal relations with the French crown. English envoys at Arras rejected the terms that excluded them, and no final peace including England was secured at the congress.

Consequences and significance

  • End of the Anglo–Burgundian alliance, removing a major diplomatic and military partner for England.
  • Political isolation of English possessions in France, which helped later French reconquest efforts.
  • Demonstration of effective French diplomacy and consolidation of royal authority under Charles VII.
  • Continuation of the war: the treaty did not end hostilities between England and France, which persisted until the mid-15th century.

The Congress of Arras is remembered not as a conclusive peace conference but as a turning point: by breaking the Burgundian alliance with England, it altered the strategic map and strengthened the French monarchy’s prospects in the later phases of the long conflict.
