## Profile

Luisa Isabel Alvarez de Toledo was the head of the House of Medina Sidonia, the most important ducal house of Spain, with its status as a hereditary title having been granted in 1445. The principal residence of the dukes was the Palace of Medina Sidonia, located in Sanlúcar de Barrameda, Cádiz. This Palace houses the Archivo de la Casa de Medina Sidonia, one of the most important private archives in Europe.

### Early years

An atypical and controversial aristocrat, she was a historian, the guardian of the ducal archives and the author of numerous works. At the age of 18, she was presented to society in Estoril, Portugal, along with the Infanta Pilar de Borbón.

### Political views

Despite her aristocratic heritage and upbringing, she held strong socialist ideals throughout her life. She is said to have been a member of the then illegal Spanish Socialist Workers' Party (PSOE).
Her anti-Francoist activities brought about her incarceration in the prison of Alcalá de Henares during the 1960s. It was from this time that she became popularly known as the "Red Duchess." She established and, until her death, was an active president of the Fundación Casa Medina Sidonia that manages the Archivo de la Casa de Medina Sidonia, the major part of the patrimony of the House of Medina Sidonia, and she continued her work as an historian and author.
