Mary of Burgundy finally agrees to sign the conclusions of the posthumous process of Burgundy, begun in 1477 at her own request, in order to fix inviolably the lands of the Dukes of Burgundy. The posthumous process of Burgundy confirms the totality of the territorial losses of Burgundy, guarantees the peace between the Crown of France and the Crown of Burgundy, and declares Charles the Bold traitor to the Kingdom. Marie's signature was made in exchange for of two additional clauses: the first is the guarantee that Marie's rights to succession to the United Duchy of Burgundy (legal entity created by the Trial, making Flanders, Brabant , and Holland, Luxembourg and the two Burgundies a single Duchy) will not be questioned, nor those of his descendants. The second clause is that of the definitive exclusion of John of Burgundy and his descendants from the succession.
The civil war breaks out in Hungary, between the nobility and the King in October 1478, when a conspiracy of nobles commits an attack against Mattias Corvin and his son. This one fails to kill the father but plunges the son in the unconsciousness, one realizes that he broke a part of the back. Mattias Corvin, furious, beheaded the two nobles who agreed to commit the attack in person, and tortured one of their accomplices to obtain a total list of the conspirators. Several militias supporting the king rise up against their lords, while the Polish and Austrian interventions, sometimes against the King, sometimes against the nobles, fuel the chaos. The nobles, believing at the beginning to have the support of the coalition against Corvin, realize in what trap it was thrown. A bloody civil war tears Hungary apart, making it unable to resist the joint invasion.
The Ottoman armies launch raids in the south of Hungary, without the goal being clearly defined. A letter from the King of Poland, signing as King of Hungary, asking the Sublime Porte to explain his motives, will receive only a very vague answer, concerning the restoration of order at the Hungarian border. Coalition armies enter Budapest on fire, defenseless after the destruction of the King's armies during the Battle of Alfold. The historian Jacques de Craonnais also enjoys the similarity between the invasion of Hungary by the coalition and the taking of the Holy Land during the first crusade, the various factions having no desire to intervene to help an ally by fear of losing one's own land.
In the end, the Emperor Frederick III, King Kazimierz IV of Poland and the Voivode of Moldavia and Wallachia Stephen III meet in Buda, capital of the Kingdom of Hungary, to decide the fate of this one. The Sultan of Constantinople also sends an emissary to secure his interests. Four treaties are signed between the four monarchs:
The Treaty of Buda is written by the King of Poland and ratified by the Diet. It authorizes the King of Poland to sign the treaties to put an end to the war, establishes the powers of the Hungarian Diet (right of censure on taxes, right of censure concerning treaties signed which affect the territory of the Kingdom of Hungary, right of meeting with the Sejm to compel the King to abdicate) and recognize him as King of Hungary.
The Treaty of Cluj is signed between the King of Romagna of the Danube, the Ottoman Sultan and the King of Hungary and Poland, at Targoviste. He enthroned Stephen III of Moldavia as King of Romagna of the Danube, and defined the borders of the Kingdom: Wallachia to the East of Arges and Transylvania are added to the Moldovan territories to form Romagna of the Danube.
The Treaty of Sopron is signed between the Archduke of Austria and the King of Poland, defining the new western border of Hungary, and the status of the Hungarians of Austria. The Austrian border encompasses a large part of the Slovaks and Croats, occupies the cities of Sopron, Esztergom, Zagreb, Györ and joins the Polish border in Arva County.
The Treaty of Vukovar is signed between the King of Hungary and the Ottoman Sultan. He granted the Sultan the administration of a march south of Hungary, the march of Syrmia, provided that part of the fortresses of the region remain under the control of the King of Hungary.
The former King of Hungary, Mattias Corvin, is captured in Fiume as he tries to reach Italy. The magnanimous King of Poland does not execute him, and only forces him to abdicate officially. He is banned from Hungary and Romagna to prevent him from seizing his former kingdom or his former duchy.
