The Armagnac Faction took its name from Charles' father-in-law, Bernard VII, Count of Armagnac, who guided the young Duke during his teens and provided much of the financing and some of the seasoned Gascon troops that besieged Paris before their defeat at Saint-Cloud. Parisian supporters of the nobles adopted the name "Armagnac" in the struggle for control of the city against the Burgundians. It was composed of two elements: the Orleanists and those following the Count who gradually infiltrated the noble opposition. Armagnac became an outspoken adherent of the Orleanist Faction in the Valois Court. His Gascon raiders hired to impose order on Paris wore their white shoulder sash. But Armagnac's brutal tactics made his administration very unpopular among Parisians. In February the citizens asked the exiled-John the Fearless to return to the capital. The following month he presented a long document known as The Justification of the Duke of Burgundy containing proof of the Armagnac schemes of intrigue. Orleans pleaded with the king, but Charles insisted on setting a meeting in Chartres to conjure a reconciliation. Meanwhile by the end of December 1409, the Burgundians had infiltrated all posts of local officials to take control of city governance. The Armagnacs withdrew altogether from city politics to form the League of Gien, they were joined by disaffected Princes of the Blood: John, Duke of Berry, the youngest brother of King Charles V, Louis, Duke of Anjou, John, Duke of Bourbon, John I, Duke of Alençon, John V, Duke of Brittany, Charles d'Albret, Constable of France, and John, Count of Clermont. These nobles formed the political and military elite of the Armagnac faction. The Burgundians met them at the Peace of Bicetres, a attempted truce designed iron out their differences. it largely failed because as the Armagnacs laid siege to Paris, a small English force landed at Calais to assist the Burgundian government. In October 1411 they marched towards Paris. In May 1412, the Armagnacs suffered a second reverse at the Treaty of Bourges. Thomas, Duke of Clarence, a fiery cavalry general, demanded considerable territorial concessions including Normandy in return for aid to Burgundy. Now desperate to save the honour of the Oriflamme the Armagnacs resorted to seeking English arbitration in the internal dispute. At the Treaty of Buzancais the English demanded a punitively large ransom from the Armagnacs. In a series of humiliating encounters their leading general, DauphinLouis, Duke of Guyenne was outmanoeuvred, defeated and forced into a Treaty of Auxerre. Later, John the Fearless was sent back to his lands, and Bernard of Armagnac remained in Paris and, some say, in the queen's bed. He was assassinated in 1419. Sporadic warfare continued between the Armagnacs and Burgundians for a number of years, although after the Burgundians allied themselves with the English in 1419 and the Armagnacs became interlinked with the cause of Charles VII, the factional rivalry was scarcely distinguishable from the Royal dispute between the French and English monarchies. The terms remained in use until they were outlawed by Charles VII toward the close of the Hundred Years' War, as part of efforts to heal the factional rift.
