### Early Life
Diogo Cão was born in 1452 in the Kingdom of Portugal. Little is recorded about his early years, but he emerged as a key figure during Portugal’s Age of Discovery.

### Expeditions
- **First Voyage (1482–1484)**: Cão sailed south along Africa’s west coast, reaching the Congo River. He established contact with the Kingdom of Kongo and erected a *padrão* at the river’s mouth.
- **Second Voyage (1484–1486)**: He continued farther south, mapping the coasts of modern-day Angola and Namibia. Additional *padrões* were placed, including one at Cape Cross.

### Legacy
Cão’s expeditions provided Portugal with strategic advantages in African trade and territorial claims. His use of *padrões* became a model for later explorers. Though he died in 1486, his work paved the way for Vasco da Gama’s voyage to India and Portugal’s colonial empire.

### Historical Artifacts
Several of Cão’s *padrões* were recovered in the 20th century, confirming his routes. These artifacts are now housed in museums, serving as tangible evidence of his contributions to exploration.
