1475 CE
A year defined by the Treaty of Picquigny between England and France, the Ottoman capture of Caffa in Crimea, and the continued Burgundian Wars against the Swiss Confederation.
Geopolitics & Diplomacy
- The Treaty of Picquigny was signed on August 29, ending Edward IV's planned invasion of France in exchange for a substantial pension from Louis XI.
- Edward IV crossed the English Channel with a large army in July, the largest English force to invade France since Agincourt, but agreed to negotiate rather than fight.
- Louis XI of France achieved a diplomatic triumph at Picquigny, neutralizing the Anglo-Burgundian alliance through financial inducements and personal diplomacy.
- Charles the Bold of Burgundy was furious at Edward IV's withdrawal, seeing the Treaty of Picquigny as a betrayal of their alliance against France.
- The Ottoman Empire under Mehmed II expanded into Crimea, challenging Genoese and Tatar control of the Black Sea region.
- Isabella and Ferdinand consolidated their position in Castile, though the War of the Castilian Succession against Juana's supporters continued.
- Ivan III of Moscow strengthened Muscovite authority over Novgorod, imposing harsh terms that reduced the city's autonomy.
Conflict & Security
- The Ottoman Empire captured the Genoese colony of Caffa in Crimea in June, establishing Ottoman control over the Black Sea and disrupting the Genoese trading network.
- Charles the Bold's forces lifted the siege of Neuss after over a year, withdrawing without achieving their objectives in the Rhineland.
- The Burgundian Wars intensified as Swiss forces, encouraged by French subsidies, prepared for direct conflict with Charles the Bold.
- The War of the Castilian Succession continued, with Portuguese forces under Afonso V supporting the claim of Juana la Beltraneja against Isabella.
- Stephen the Great of Moldavia defeated an Ottoman invasion force at the Battle of Vaslui in January, one of the greatest Christian victories against Ottoman expansion.
- Ottoman naval power in the Black Sea expanded following the capture of Caffa, threatening remaining Genoese and Venetian outposts.
- Edward IV's army disbanded after the Treaty of Picquigny, returning to England without having engaged in significant combat.
Economy & Finance
- Edward IV received a generous annual pension from Louis XI under the Treaty of Picquigny, supplementing English crown revenues without the cost of war.
- The fall of Caffa disrupted Genoese commercial networks in the Black Sea, forcing merchants to seek alternative trade routes.
- The financial costs of Charles the Bold's military campaigns strained Burgundian resources and contributed to growing discontent among his subjects.
