Pedro Mascarenhas led an expedition in 1512 that resulted in the discovery of the Indian Ocean island of Diego Garcia. A career diplomat and administrator under the Portuguese crown, he spent his life navigating both the geopolitical currents of the Holy See and the maritime expansion of the Kingdom of Portugal across the sixteenth-century world.
Maritime Expeditions
During his travels in 1512, Mascarenhas encountered Mauritius. While historical records remain debated regarding whether he was the first European to arrive at that specific location, his name was later used to identify the entire archipelago. In 1528, the explorer Diogo Rodrigues designated the islands of Réunion, Mauritius, and Rodrigues as the Mascarene Islands to honor his earlier voyages through these waters.

Serving as an ambassador for Portugal to the Holy See, Mascarenhas acted upon the requests of King John III and Diogo de Gouveia to advocate for missionary work. He successfully petitioned Pope Paul III to secure the deployment of the first Jesuits to the Portuguese missions in India. His tenure in Rome concluded on 15 March 1540, after which he accompanied Francis Xavier back to Portugal. Upon his return, he took up responsibilities within the royal court, focusing on the household and education of Prince John.
Administrative Assignments
The Portuguese crown frequently utilized Mascarenhas for significant administrative and strategic tasks. In 1549, he played a central role in the controlled withdrawal from fortresses located in Morocco. Later, despite his attempts to decline the appointment due to his advanced age, King John III compelled him to serve as the Viceroy of the Portuguese Provinces of India. He assumed this position in 1554.
Final Years in India
Based in Goa, which served as the capital for Portuguese possessions in Asia, Mascarenhas directed administrative operations from 1554 until his death in 1555. This mission aimed to assess the willingness of Emperor Galawdewos to accept a Patriarch appointed by the Roman Catholic Church. Following his death in Old Goa in 1555, he was succeeded in the viceregal post by Francisco Barreto.
