The province was created on January 4, 1540, by the Master General of the Order of Preachers, Friar AgustÃÂn Recuperato de Favencia. It was headquartered at the Convent of the Holy Rosary. The Order's study room led to the establishment of the National University of San Marcos (then the Royal and Pontifical University of the City of the Kings of Lima) and its later autonomous Faculty of Theology.
Known members of the Order include saints Rose of Lima, Martin de Porres, and John Macias, as well as blessed Ana of the Angels Monteagudo.
The province is headed by a prior chosen by the chapter's friars.
