Joan of Arc Acquitted of Heresy in Posthumous Retrial

In the mid-15th century, France remained embroiled in the Hundred Years' War with England, and Joan of Arc had emerged as a charismatic military leader who inspired French forces before her capture and execution in 1431 on charges of heresy. Twenty-five years later, at the request of her family and amid efforts to rehabilitate her reputation and bolster French national identity, a retrial convened in Rouen under ecclesiastical authorities. The proceedings examined the original trial's irregularities, including procedural flaws and political motivations tied to English influence. On July 7, 1456, the court issued a verdict declaring Joan innocent of heresy, nullifying the prior condemnation. This outcome restored her standing as a national heroine and set precedents for later canonization processes in the Catholic Church.

Why it matters: The acquittal immediately helped legitimize the French monarchy's narrative of divine support during the war's final phases and contributed to the erosion of English claims in France. Over centuries, it transformed Joan into a enduring symbol of resistance and faith, influencing French cultural identity and culminating in her sainthood in 1920.

Hunyadi's Forces Repel Ottomans at Belgrade

In the mid-15th century, the Ottoman Empire under Sultan Mehmed II sought to expand into Europe following the 1453 fall of Constantinople. Hungarian regent John Hunyadi organized a defense of the strategic fortress city of Belgrade, then part of the Kingdom of Hungary, bolstered by crusader volunteers and local forces. Ottoman troops besieged the city starting in early July, deploying heavy artillery and naval forces on the Danube. On July 21, Mehmed launched a major assault that nearly breached the walls, but defenders held firm. The next day, July 22, the Ottomans faced a determined counterattack and supply issues, prompting Mehmed, who was wounded, to lift the siege and retreat. This outcome preserved Hungarian control over the Danube frontier for decades.

Why it matters: The victory halted Ottoman momentum into Central Europe immediately after Constantinople's conquest, buying time for Christian states to regroup. It demonstrated the effectiveness of combined peasant, knight, and crusader forces against superior numbers and artillery. Long-term, the event inspired later resistance and contributed to the broader pattern of Ottoman-Habsburg conflicts that defined European borders for centuries.
