The Truce of Leulinghem was a truce agreed to by Richard II's Kingdom of England and its allies, and Charles VI's Kingdom of France and its allies, on 18 July 1389, ending the second phase of the Hundred Years' War. England was on the edge of financial collapse and suffering from internal political divisions. On the other side, Charles VI was suffering from a mental illness that handicapped the furthering of the war by the French government. Neither side was willing to concede on the primary cause of the war, the legal status of the Duchy of Aquitaine and the King of England's homage to the King of France through his possession of the duchy. However, both sides faced major internal issues that could badly damage their kingdoms if the war continued. The truce was originally negotiated by representatives of the kings to last three years, but the two kings met in person at Leulinghem, near the English fortress of Calais, and agreed to extend the truce to a twenty-seven years' period.
