The Order of the Brothers of the Blessed Virgin Mary of Mount Carmel (Ordo Fratrum Beatissimæ Virginis Mariæ de Monte Carmelo; abbreviated OCarm), known as the Carmelites or sometimes by synecdoche known simply as Carmel, is a Roman Catholic mendicant religious order for men and women. Historical records about its origin remain uncertain, but it was probably founded in the 12th century on Mount Carmel in the Crusader States. Berthold of Calabria, as well as Albert of Vercelli, have traditionally been associated with the founding of the order, but few clear records of early Carmelite history have survived. The order of Carmelite nuns was formalised in 1452. The Carmelite Order is one of the few monastic orders, if not the only one, not to refer to a charismatic founder, but to a prophet of the Old Testament: Elijah and his disciple Elisha are considered by the Carmelites as the spiritual fathers of the order. Tradition indicates the presence on Mount Carmel of a series of Jewish and then Christian hermits who lived, prayed and taught in the caves used by Elijah and Elisha. This is how the first Christian hermits (at the origin of the founding of the order), settled in the caves of Mount Carmel to pray to God. The first chapel built within the hermitages and bringing together this community is dedicated to the Virgin Mary. Very quickly, the spirituality of the order turned to Mary who became the queen and mistress of Carmel. Hermits of the Most Blessed Virgin Mary of Mount Carmel Before the presence of the Carmelites, in the 6th century Byzantine monks built a monastery dedicated to Saint Elijah in a valley a few kilometers south of the present monastery. This was destroyed in 614 by the Persians of Khosrow II. Around 1150, a Greek monk from Calabria established a community of about ten members among the ruins of the ancient Byzantine monastery which he rebuilt and renamed Saint Elijah. Tradition indicates that the order was founded in 1185, but that is based on the story of a pilgrim in the Holy Land, the interpretation of which remains questionable.
