IV Meeting of Young Researchers in Modern History, Barcelona, 6-7 July 2017, Autonomous University of Barcelona. María de Guadeloupe de Lempstre was VI duquesa de Aveiro (since 20 October 1679), Arcos and Macura. He was born in Azeitão on 11 January 1630 and died in Madrid on 9 February 1715. His life was horse between Portugal and Spain, as he lived in the Portuguese kingdom until 1660, when he moved next to his mother to Madrid, where the Spanish stage began. In 1665 she married the sixth duke of Arcos, Manuel Ponce de León, and, as a result of this union, three children were born. We are faced with a cultured figure, familiar with languages and various knowledge, founder, mission sponsor and owner of large and interesting libraries, including the figure deposited at the Santa Eulalia convent, comparable only to real female libraries at this time. The study of the character’s cultural profile opens us a new field of binomial (comparative and evolutionary) research for a specific model of woman living in the middle and under the cultural and political influence of two reindeers and two families. Attention is drawn to the complete disciplinary training of duquess and the consequent exteriorisation of the duquess throughout its life. The research is carried out under the project linked to the Ministry of Economy and Competitiveness: HAR2014-54492-P, ‘aristocratic cultures in the Iberian gold century: uses, models, knowledge and political communities’.
