The Portuguese royal family refers to the historical lineage of monarchs who ruled Portugal from the 12th century until the establishment of the republic in 1910. The most notable dynasty was the House of Aviz, which produced famous kings like King John I and King Manuel I. The monarchy played a significant role in Portugal's Age of Discoveries, expanding its influence across the globe. Today, the title of the head of the Portuguese royal family is held by Dom Duarte Pio, the Duke of Braganza. Although Portugal is a republic, the royal family remains active in cultural and charitable activities, preserving the country's rich history and traditions.
