Source-derived summary

The Casa da Guiné (English: House of Guinea), later known as the Casa da Guiné e Mina and also referred to as the Portuguese Guinea Company, was a state-run Portuguese commercial institution, tasked with the management of the Portuguese Empire's economic interests and colonization in West Africa, particularly on the Gulf of Guinea, on the Gold Coast, and on the Slave Coast.

History

Founded in 1443, during the Age of Discoveries, under the auspices of Prince Henry the Navigator, the Casa da Guiné would later be absorbed into the Casa da Índia in 1503.

Operations

It monitored and enforced the Crown's monopoly, coordinated voyages, maintained warehouses, fixed prices, and performed other roles associated with the Spice trade. It was also where an average of 1,000 slaves were taken from Africa to be sold each year for nearly 50 years.

Editorial summary

Editorial reviewA useful synthesis for locating the documentary relationships between formal authority, participants and affected communities. The current lead gives the account dated anchors—1443, 1503—that can be checked directly. The linked authority record independently contributes the date 1444. Its value is orientation rather than verdict, with Casa, Guiné and Portuguese providing the first useful test.

Why this record matters

Evidence profile

The record creator and administrative purpose are central evidence, because official documentation reflects both action and institutional priorities.

Critical limits

Official terminology may obscure informal participation, dissent or communities documented only indirectly.
