The secularist cultural policy implemented in Portugal after the proclamation of the Republic on October 5th, 1910, contributed to the shaping of anticlerical actions that were intended to terminate the activities of the Catholic Church in the country. In response, members of the clergy engaged in re-catholization projects proposed by the Roman Curia, as international actions in the first decades of the twentieth century. In this paper, which has an approach focused on the Cultural History of Religions, we observe how the apparitions of Our Lady of Fatima, from May 1917 on, were used to reaffirm the ecclesiastical discourse, and to build a visionary culture in the Luso-Brazilian world. Our narrative also analyzes the internationalization of such worship, especially its practices and representations in Brazil.1733561585
