British Community and Family History
The Anglo-Portuguese Treaty of 1654, following Portugal's misguided support of Prince Rupert, a Cavalier commander during the English Civil War, was the most important commercial treaty between England and Portugal in the 17th century, imposed on Portugal by the British. It marked the beginning of Britain's overriding influence on the Portuguiese economy, which would last until the 20th century. The English merchants trading in Portugal were henceforth in a more advantageous situation than were their Portuguese competitors. The purpose of the research reported in this article was to determine exactly who these Englishmen were.
