Portuguese nobility titles

Portuguese nobility titles historically signified social rank and landholding privilege, often granted by the monarchy. The main titles include *Duke* (highest rank below royalty), *Marquis*, *Count*, *Viscount*, and *Baron*. Titles could be inherited or bestowed for loyalty or service. Over time, many noble privileges diminished, but titles remain as symbols of historical heritage. Some titles are accompanied by land or estate rights, while others are purely honorary. The Portuguese system reflects a hierarchical social structure rooted in medieval feudalism, with noble titles serving to recognize influence, loyalty, or service to the crown.
