The "Barons of Portugal" refers to a title of nobility historically granted to landowners and influential figures in Portuguese society. These barons played significant roles in the governance and administration of their regions, often managing large estates and contributing to local economies. The title was part of the broader feudal system that characterized medieval Portugal. During the Age of Discovery, some barons became prominent explorers and patrons of expeditions, helping to expand Portugal's influence overseas. Their contributions were vital in establishing trade routes and colonies, which significantly impacted the Portuguese Empire and global trade during the 15th and 16th centuries.
