What is the nationality of Juan Rodríguez Cabrillo?

Juan Rodríguez Cabrillo was a Portuguese explorer sailing under the Spanish flag, so identifying him as Spanish aligns with the nationality he represented during his significant explorations along the California coast in the 16th century. Cabrillo is best known for being the first European to navigate the coastal areas of present-day California, particularly during his expedition in 1542. His explorations were conducted under the auspices of the Spanish crown, and while he was born in Portugal, his major contributions to exploration were linked with Spain, making the designation of him as Spanish appropriate in the context of his explorations and the historical period.
