About Infanta Maria Doroteia of Portugal

Lived 1739 – 1771 (aged 31). Infanta Maria Doroteia of Portugal was an aristocrat.

Doroteia of Braganza (21 September 1739 – 14 January 1771) was a Portuguese infanta as the daughter of King Joseph I of Portugal and Mariana Victoria of Spain.

Life Doroteia was born on 21 September 1739 in Lisbon. She was the third of four daughters of Joseph I of Portugal and Mariana Victoria of Spain. She was named after her great-grandmother, Dorothea Sophie of Neuburg.

Doroteia was a proposed bride for Philippe d'Orléans, Duke of Orléans (later known as Philippe Égalité), but her mother refused to consent to the match.

In 1764, she became ill in a condition described as “hysteric, accompanied by an almost total lack of appetite which has reduced her to a state of extreme weakness.” She was subjected to numerous bleedings before dying in Lisbon on 14 January 1771. Her body was moved to the national pantheon in the Monastery of São Vicente de Fora, in Lisbon.
