Carlos Testa

Carlos Testa (1823–1891), also listed in some sources as Carlos André Testa, was a Portuguese naval officer and writer. The title page of his best-known book, Portugal e Marrocos perante a historia e a politica europea (1888), identifies him as a capitão de mar e guerra—roughly a captain in the navy—and Project Gutenberg’s catalog records his life dates as 1823–1891.

His writing focuses on history, diplomacy, and maritime affairs. In Portugal e Marrocos, he examines the relationship between Portugal and Morocco through the wider lens of European politics, drawing on Portugal’s naval past and colonial ambitions to make a political argument about the country’s role in North Africa.

A later study of Portuguese naval historiography includes Carlos André Testa among the Navy’s historical writers, which suggests he was remembered not only as an officer but also as part of a broader tradition of naval authors. I couldn’t confidently confirm more personal biographical details from reliable sources available here, so this overview stays close to the record that can be verified.
