Spain and Portugal agreed to a meridian-based division of newly encountered lands, later used by Portugal to justify its claim to the Brazilian coast that fell within the Portuguese sector.
Pedro Álvares Cabral’s India-bound armada made landfall on the Brazilian coast, an event traditionally dated to 22 April 1500, initiating Portuguese reconnaissance and claims along the South Atlantic littoral.
Friar Henrique de Coimbra celebrated what is commonly identified as the first Catholic mass in Brazil during Cabral’s stop on the Bahian coast, described in contemporary reporting from the voyage.
Royal scribe Pêro Vaz de Caminha finalized his detailed report to King Manuel I from Porto Seguro, one of the earliest and most important eyewitness descriptions of the land and peoples encountered on the Brazilian coast.
Astronomer-physician João Faras ("Mestre João") wrote to King Manuel I from Vera Cruz, noting observations useful for navigation (including the southern sky) amid early efforts to situate the new coast geographically.
A Portuguese expedition associated with Gonçalo Coelho, with Amerigo Vespucci aboard, sailed from Lisbon and reached the Brazilian coast, contributing new coastal observations that fed early Portuguese cartography.
On the Coelho–Vespucci voyage, the expedition entered Guanabara Bay on New Year’s Day and applied the name “Rio de Janeiro,” reflecting ongoing Portuguese practice of naming and charting notable points along the coast.
Smuggled from Portugal in 1502, the Cantino planisphere is the earliest surviving map showing Portuguese discoveries with a fragmentary but crucial depiction of the Brazilian coast—evidence of rapid translation from exploration to state cartography.
In early Portuguese records the land was quickly referred to as Terra de Santa Cruz (“Land of the Holy Cross”), reflecting evolving understanding that the landfall was not an island and helping stabilize official nomenclature for the coast being reconnoitered.
King Manuel I donated the Fernando de Noronha archipelago (strategically placed on Atlantic routes) as a hereditary captaincy in 1504, underscoring how navigation corridors and waypoints complemented coastal exploration of Brazil.
The Caverio (Canerio) planisphere, dated circa 1506, preserved and circulated a synthesis of recent discoveries, including information about Brazil, helping diffuse Iberian Atlantic geographic knowledge into broader European cartographic practice.
By 1516 Portuguese royal administration used the term “Brazil” in an official capacity, appointing Cristóvão Jacques as governor of the parts of Brazil, reflecting the shift from sporadic reconnaissance toward more regularized coastal oversight.
The richly illustrated 1519 Miller Atlas includes the chart commonly called Terra Brasilis, depicting the Brazilian coastline with extensive toponyms and imagery (including brazilwood extraction), marking a mature stage of Portuguese coastal knowledge after two decades of exploration.
Martim Afonso de Sousa commanded the first sustained colonizing expedition to Brazil (1530–33), representing a transition beyond earlier reconnaissance and mapping toward organized settlement and tighter Portuguese control along the coast.
