John II of Portugal Sends Pêro da Covilhã on a Secret Mission to the East (1487)

In 1487, King John II of Portugal sent Pêro da Covilhã on a covert reconnaissance mission to the Middle East and India, seeking information about the spice trade, sea routes to the Indian Ocean, and the legendary Christian kingdom of Prester John. This mission was one of the most critical intelligence-gathering expeditions of the Age of Exploration, laying the groundwork for Portugal’s later maritime expansion into Asia.


The Goals of Covilhã’s Mission

John II’s main objectives in sending Covilhã eastward were:

  1. Gather Intelligence on the Indian Ocean Trade

    • Portugal sought to bypass Muslim and Venetian intermediaries in the lucrative spice trade.
    • Covilhã was to investigate how spices, especially pepper and cinnamon, reached the Mediterranean.
  2. Confirm the Feasibility of a Sea Route to India

    • Portugal had been exploring westward along the African coast, but no one had yet circumnavigated Africa to reach the Indian Ocean.
    • Covilhã’s mission was to travel overland and determine if a Portuguese fleet could eventually reach India by sea.
  3. Seek the Kingdom of Prester John

    • Europeans believed in the existence of a powerful Christian kingdom in East Africa, ruled by Prester John, who could serve as an ally against Muslim powers.
    • Covilhã was to locate this mythical ruler and establish diplomatic contact.

Covilhã’s Journey (1487–1493)

Accompanied by Afonso de Paiva, another Portuguese agent, Covilhã traveled undercover as an Arab merchant.

  • 1487: Departed from Lisbon, sailed to Naples, Rhodes, and Alexandria (Egypt).
  • 1488: Traveled through Cairo to the Red Sea, where he visited Aden (Yemen).
  • 1489: Reached India, visiting Calicut and Goa, where he gathered firsthand information on the spice trade.
  • 1490–1491: Returned to the Arabian Peninsula, visiting Hormuz (Persia) and Mecca, before heading to East Africa.
  • 1493: Arrived in Abyssinia (Ethiopia), where he was detained at the court of the Ethiopian emperor, effectively ending his ability to return to Portugal.

Results and Legacy of Covilhã’s Mission

  • He confirmed that India could be reached by sailing around Africa, validating Portuguese exploration efforts.
  • His reports were delivered to Portugal via messengers, influencing Vasco da Gama’s 1497 voyage to India.
  • He was one of the first Europeans to document the trade networks of the Indian Ocean, providing critical geographical and commercial intelligence.
  • His arrival in Ethiopia strengthened Portuguese-Ethiopian relations, though he was never allowed to leave.

Conclusion: A Crucial Step Toward Portuguese Global Expansion

Though Pêro da Covilhã never returned to Portugal, his mission played a key role in shaping Portugal’s future exploration efforts. His intelligence confirmed the viability of a sea route to India, leading directly to Vasco da Gama’s successful voyage to India in 1498, establishing Portugal as the dominant European power in the Indian Ocean.
