Carlota Joaquina of Spain
Doña Carlota Joaquina of Spain ("Carlota Joaquina Teresa Cayetana";
25 April 1775 – 7 January 1830), was by birth a member of the Spanish branch of the House of Bourbon and Infanta of Spain and by marriage Queen consort of Portugal.
Eldest daughter of King Charles IV of Spain and Maria Luisa of Parma, she was married in May 1785 aged 10 with Infante John, Lord of the Infantado and Duke of Beja, second son of Queen Maria I of Portugal, in an attempt to cement ties between the Kingdoms of Spain and Portugal.
Detested by the Portuguese court — where she was called "the Shrew of Queluz"  — Carlota Joaquina also gradually won the antipathy of the people, who accused her of promiscuity and influencing her husband in favor of the interests of the Spanish crown.
After the escape of the Portuguese court to Brazil, Carlota Joaquina began conspiring against her husband, claiming that he had no mental capacity to govern Portugal and its possessions, thus wanting to establish a regency.
Ambitious, she also planned to usurp the Spanish crown that was in the hands of Napoleon's brother Joseph Bonaparte.
After the marriage in 1817 of her son Pedro with the Archduchess Leopoldina of Austria and the later return of the royal family to Portugal in 1821, Carlota Joaquina was confined in the Royal Palace of Queluz, where she died alone and abandoned by her children on 7 January 1830.
After her death, Carlota Joaquina (mainly in Brazil) became part of popular culture and an important historical figure, being the subject of several books, films and other media.
Some scholars believe that she has had a rough and superficial behavior, attributing to her the fact that she hated Brazil.
