Directory

1494 CE

A year defined by the Treaty of Tordesillas dividing the New World, the French invasion of Italy launching the Italian Wars, and the rise of Savonarola in Florence.

Geopolitics & Diplomacy

  • The Treaty of Tordesillas was signed on June 7 between Spain and Portugal, dividing newly discovered lands along a meridian 370 leagues west of the Cape Verde Islands.
  • King Charles VIII of France invaded Italy in September with a large army, asserting his claim to the Kingdom of Naples and launching the Italian Wars.
  • Ludovico Sforza of Milan had encouraged the French invasion to weaken Naples, but soon realized the threat that French power posed to all Italian states.
  • Piero de' Medici, son of Lorenzo, was expelled from Florence in November after surrendering key fortresses to Charles VIII without consulting the city's government.

Conflict & Security

  • The French army under Charles VIII crossed the Alps in September and marched through northern Italy, encountering little organized resistance.
  • French forces entered Florence in November, forcing the expulsion of the Medici and imposing harsh terms on the city.
  • The Italian Wars began with the French invasion, inaugurating a period of conflict that would devastate the Italian peninsula for over sixty years.

Economy & Finance

  • The Treaty of Tordesillas secured Portugal's claim to the eastern Atlantic and what would become Brazil, ensuring its access to African and Asian trade.
  • The French invasion of Italy disrupted trade networks across the peninsula, with merchants and bankers facing uncertainty and financial losses.
  • The expulsion of the Medici from Florence destabilized the city's banking and commercial operations, though trade continued under the new republican government.
