Isabel Maria de Alcântara, Duchess of Goiás

Life

Isabel Maria de Alcântara, Duchess of Goiás, was born in Rio de Janeiro on 3 May 1824. Her birth was recorded as that of a child of unknown parents, supposedly left at the home of Colonel João de Castro, who was actually her maternal grandfather. She was baptized on 31 May in the church of São Francisco Xavier do Engenho Velho, with the parents of the Marchioness of Santos acting as godparents. Just before her second birthday, Emperor Pedro I of Brazil officially recognized her as his daughter—the only one of his illegitimate children he ever legitimized—and ordered the baptism record to be changed to reflect this.

On 24 May 1826, he issued a decree granting her the title of Duchess of Goiás, the style of Highness, and the right to use the honorific "Dona." This made her the first person to hold a ducal title in the newly formed Empire of Brazil. The decree caused a stir at court, and the event was marked by a grand gala celebration at the Palace of Caminho Novo, the emperor’s lavish residence built for his mistress, the Marchioness of Santos. On 6 June 1826, before the entire court, the duchess was formally introduced to Empress Maria Leopoldina of Austria.

After that, she lived at the palace daily, receiving an education alongside her paternal half-sisters, the emperor’s legitimate daughters. Following Empress Maria Leopoldina’s death in December 1826, Isabel Maria moved permanently into the Palace of São Cristóvão with her father in August 1827. In 1829, Pedro I remarried and ended his relationship with the Marchioness of Santos, who was sent back to São Paulo. The new empress, Amélie of Leuchtenberg, refused to allow the illegitimate daughter to remain at São Cristóvão, so before Amélie arrived in Brazil, Isabel Maria was sent to the Palace of Praia Grande, the imperial summer residence in Niterói, in the province of Rio de Janeiro.
