The "Princess of Portugal" typically refers to a female member of the royal family of Portugal. Historically, the title has been held by daughters or granddaughters of the reigning monarch. The role often involved diplomatic marriages and alliances with other European royal families. In the context of Portuguese history, notable figures include Infanta Isabel, who was a prominent princess in the 14th century. The title has evolved over time, especially after the abolition of the monarchy in 1910, but descendants of the royal family still carry the title in a ceremonial capacity.
