This study on Muslims in the municipality of Sintra in the Lisbon Metropolitan Area, Portugal, promotes an ethnographic approach to their socioeconomic, cultural, and religious realities. Commissioned by Sintra City Council, (Solidarity and Social Innovation), it aims to understand Muslims' socioeconomic insertion in one of the regions with the greatest cultural and religious diversity in the country. It is a study that aims particularly to address gender issues that have been neglected in the studies of Muslims in Portugal. This study, coordinated by José Mapril (CRIA-FCSH) and Raquel Carvalheira (CRIA-FCSH), results from CRIA’s commitment to promoting the dissemination of anthropology in the community and allows it to strengthen the relations between science and the local public administration.
