  1. Background

    Portuguese Atlantic expansion and Columbus's 1492 voyage sharpened a dispute over navigation, trade, and claims to lands unknown to the two Iberian courts. After papal bulls favored Castile, Portuguese and Castilian envoys negotiated a new boundary at Tordesillas.

  2. Course

    Representatives signed the treaty on 7 June 1494. It assigned newly claimed lands east of the line to Portugal and those west of it to Castile, although contemporary navigators could not fix the meridian precisely and the agreement did not settle an opposite line in Asia.

  3. Outcome

    The settlement gave the two crowns a diplomatic framework for rivalry and helped place the eastern part of South America within Portugal's sphere, later associated with Brazil. Further disputes produced the Treaty of Zaragoza in 1529, and settlement and conquest repeatedly crossed the paper boundary.

  4. Historical significance

    Tordesillas divided Spanish and Portuguese claims; it did not allocate French Saint-Domingue. French possession of western Hispaniola followed the 1697 Treaty of Ryswick. Its link to the Haitian Revolution is structural rather than direct: Haiti ruptured the longer Atlantic colonial order by defeating French colonial slavery.
