Maria Pia de Saxe-Coburgo e Bragança (March 13, 1907 – May 6, 1995), also known by her literary pseudonym Hilda de Toledano, was a Portuguese writer and journalist who claimed to be the bastard daughter of King Carlos I of Portugal.
From 1932 she also claimed the right to the title of Duchess of Braganza and to be the rightful heiress to the throne of Portugal.Maria Pia of Braganza claimed that King Carlos I legitimized her through a royal decree and placed her in the line of succession, however no proof was presented to demonstrate this and the King similarly did not have the personal authority to do so.
Maria Pia's paternity was never proven and her claim to the throne or of royal ancestry never widely accepted.
