Martim Afonso de Sousa’s expedition

The colonising expedition of Martim Afonso de Sousa, sent by Dom João III in 1530, represented the first official and organised attempt at Portuguese occupation of the territory that would become Brazil.

Comprising ships, soldiers, settlers and technicians, the mission’s main objectives were to combat the French trading posts already established on the coast, to survey and explore the coast between Maranhão and Rio da Prata, and to create settlements capable of exercising political and administrative authority on behalf of the crown.

Throughout the voyage, the fleet proceeded to demarcate strategic points, established contact with indigenous populations, and faced logistical difficulties and local hostilities.

The most lasting result was the founding of settlements, including São Vicente in 1532, the starting point for organised Portuguese colonisation in America, which consolidated the Portuguese-Brazilian presence and paved the way for subsequent economic exploitation and territorial administration.
