CrusadesThe Crusades were a series of religious wars initiated, supported, and sometimes directed by the Christian Latin Church in the medieval period. The best known of these military expeditions are those to the Holy Land in the period between 1095 and 1291 that were intended to conquer Jerusalem and its surrounding area from Muslim rule. Beginning with the First Crusade, which resulted in the conquest of Jerusalem in 1099, dozens of military campaigns were organised, providing a focal point of European history for centuries.
PurgatoryPurgatory ( purgatorium, borrowed into English via Anglo-Norman and Old French) is, according to the belief of some Christian denominations and Islam, an intermediate state after physical death for expiatory purification. The process of purgatory is the final purification of the elect, which is entirely different from the punishment of the damned. Tradition, by reference to certain texts of scripture, sees the process as involving a cleansing fire. Some forms of Western Christianity, particularly within Protestantism, deny its existence.
Eastern OrthodoxyEastern Orthodoxy, otherwise known as Eastern Orthodox Christianity or Byzantine Christianity, is one of the three main branches of Chalcedonian Christianity, alongside Roman Catholicism and Protestantism. Like the Pentarchy of the first millennium, the mainstream (or "canonical") Eastern Orthodox Church is organised into autocephalous churches independent from each other. In the 21st century, the number of mainstream autocephalous churches is seventeen; there also exist autocephalous churches unrecognized by those mainstream ones.
Franco-Mongol allianceSeveral attempts at a Franco-Mongol alliance against the Islamic caliphates, their common enemy, were made by various leaders among the Frankish Crusaders and the Mongol Empire in the 13th century. Such an alliance might have seemed an obvious choice: the Mongols were already sympathetic to Christianity, given the presence of many influential Nestorian Christians in the Mongol court.
SacramentA sacrament is a Christian rite that is recognized as being particularly important and significant. There are various views on the existence, number and meaning of such rites. Many Christians consider the sacraments to be a visible symbol of the reality of God, as well as a channel for God's grace. Many denominations, including the Catholic, Lutheran, Anglican, Methodist, and Reformed, hold to the definition of sacrament formulated by Augustine of Hippo: an outward sign of an inward grace, that has been instituted by Jesus Christ.
CarmelitesThe 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.
Kingdom of SicilyThe Kingdom of Sicily (Regnum Siciliae; Regno di Sicilia; Regnu di Sicilia) was a state that existed in the south of the Italian Peninsula and for a time the region of Ifriqiya from its founding by Roger II of Sicily in 1130 until 1816. It was a successor state of the County of Sicily, which had been founded in 1071 during the Norman conquest of the southern peninsula. The island was divided into three regions: Val di Mazara, Val Demone and Val di Noto.
Dominican OrderThe Order of Preachers (Ordo Praedicatorum) abbreviated OP, also known as the Dominicans, is a Catholic mendicant order of pontifical right founded in France, by a Spanish priest, saint and mystic, Dominic. It was approved by Pope Honorius III via the papal bull Religiosam vitam on 22 December 1216. Members of the order, who are referred to as Dominicans, generally carry the letters OP after their names, standing for Ordinis Praedicatorum, meaning of the Order of Preachers.
FranciscansThe Franciscans are a group of related mendicant Christian religious orders within the Catholic Church. Founded in 1209 by the Italian saint Francis of Assisi, these orders include three independent orders for men (the Order of Friars Minor being the largest contemporary male order), orders for nuns such as the Order of Saint Clare, and the Third Order of Saint Francis open to male and female members. They adhere to the teachings and spiritual disciplines of the founder and of his main associates and followers, such as Saint Clare of Assisi, Saint Anthony of Padua, and Saint Elizabeth of Hungary.
Catholic ChurchThe Catholic Church, also known as the Roman Catholic Church, is the largest Christian church, with 1.3 billion baptized Catholics worldwide It is among the world's oldest and largest international institutions, and has played a prominent role in the history and development of Western civilization. The church consists of 24 sui iuris churches, including the Latin Church and 23 Eastern Catholic Churches, which comprise almost 3,500 dioceses and eparchies located around the world.
