There are a number of Roman Catholic religious orders or congregations with Immaculate Conception in their name. Several of them are discussed here. Order of the Immaculate Conception of Our Lady (The Conceptionists) Founded in 1484 at Toledo, Spain, by Saint Beatrice of Silva, sister of Blessed Amadeus of Portugal. On the marriage of Princess Isabella of Portugal with King John II of Castile, Beatrice had accompanied the queen to the court of her husband, but her great beauty having aroused the jealousy of the queen, she escaped with difficulty and took refuge in the Dominican convent at Toledo. Here for forty years she led a life of holiness, without becoming a member of the Order. Inspired by an apparition of the Virgin Mary to found a new congregation in her honour, Beatrice of Silva, with some companions, took possession of a convent (the Convent of the Order of the Immaculate Conception) set apart for them by Queen Isabella I of Castile in Toledo. In 1489, by permission of Pope Innocent VIII, the sisters adopted the Cistercian rule, bound themselves to the daily recitation of the Office of the Immaculate Conception, and were placed under obedience to the ordinary of the archdiocese. In 1501, Pope Alexander VI united this congregation with the Benedictine community of San Pedro de las Duenas, under the Rule of St. Clare, but in 1511 Julius II gave it a rule of its own, and in 1616 special constitutions were drawn up for the congregation by Cardinal Francisco de Quiñones. The second convent was founded in 1507 at Torrigo, from which, in turn, were established seven others. The congregation soon spread through Portugal, Spain, Italy, and France. The foundress determined on the habit, which was white, with a white scapular and blue mantle. The foundress, Beatrice of Silva Menezes (sometimes cited as "Brites") (1424–90), was canonized by Pope Paul VI in 1976; her feast day is 1 September. Mission Priests of the Immaculate Conception (usually called Missionaries of Rennes) Founded at St-Méen in the Diocese of Rennes, by Jean-Marie-Robert de Lamennais, for the care of the diocesan seminary and the holding of missions. The disciples of the founder's younger brother, Félicité de Lamennais, in 1829 withdrew with him into the solitude of La Chênaie, forming the Society of St. Peter, with which the elder community at its own request was united, under the superiorship of Félicité.
