Middle AgesIn the history of Europe, the Middle Ages or medieval period (also spelled mediæval or mediaeval) lasted approximately from the late 5th to the late 15th centuries, aligning with the post-classical period of global history. It began with the fall of the Western Roman Empire in 476 AD and ended with the fall of Constantinople in 1453 AD before transitioning into the Renaissance and then the Age of Discovery. The Middle Ages is the middle period of the three traditional divisions of Western history: antiquity, medieval, and modern.
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.
Crusader statesThe Crusader states, also known as Outremer, were four Catholic realms in the Middle East that lasted from 1098 to 1291. These feudal polities were created by the Latin Catholic leaders of the First Crusade through conquest and political intrigue. The four states were the County of Edessa (10981150), the Principality of Antioch (10981287), the County of Tripoli (11021289), and the Kingdom of Jerusalem (10991291). The Kingdom of Jerusalem covered what is now Israel, the West Bank, the Gaza Strip, and adjacent areas.
Bernard of ClairvauxBernard of Clairvaux, O. Cist. (Bernardus Claraevallensis; 1090 - 20 August 1153), venerated as Saint Bernard, was an abbot, mystic, co-founder of the Knights Templar, and a major leader in the reformation of the Benedictine Order through the nascent Cistercian Order. He was sent to found Clairvaux Abbey at an isolated clearing in a glen known as the Val d'Absinthe, about southeast of Bar-sur-Aube. In the year 1128, Bernard attended the Council of Troyes, at which he traced the outlines of the Rule of the Knights Templar, which soon became an ideal of Christian nobility.
SaladinSalah al-Din Yusuf ibn Ayyub (1137 – 4 March 1193), commonly known as Saladin (Honour of the Faith), was the founder of the Ayyubid dynasty. Hailing from a Kurdish family, he was the first sultan of both Egypt and Syria. An important figure of the Third Crusade, he spearheaded the Muslim military effort against the Crusader states in the Levant. At the height of his power, the Ayyubid realm spanned Egypt, Syria, Upper Mesopotamia, the Hejaz, Yemen, and Nubia.
Kingdom of JerusalemThe Kingdom of Jerusalem, also known as the Latin Kingdom of Jerusalem, was a Crusader state that was established in the Levant immediately after the First Crusade. It lasted for almost two hundred years, from the accession of Godfrey of Bouillon in 1099 until the siege of Acre in 1291. Its history is divided into two periods with a brief interruption in its existence, beginning with its collapse after the siege of Jerusalem in 1187 and its restoration after the Third Crusade in 1192.
Ayyubid dynastyThe Ayyubid dynasty (الأيوبيون al-Ayyūbīyūn; ئەیووبیەکان, Eyûbiyan), also known as the Ayyubid Empire, was the founding dynasty of the medieval Sultanate of Egypt established by Saladin in 1171, following his abolition of the Fatimid Caliphate of Egypt. A Sunni Muslim of Kurdish origin, Saladin had originally served Nur ad-Din of Syria, leading Nur ad-Din's army in battle against the Crusaders in Fatimid Egypt, where he was made Vizier.
Third CrusadeThe Third Crusade (1189–1192) was an attempt led by three European monarchs of Western Christianity (Philip II of France, Richard I of England and Frederick I, Holy Roman Emperor) to reconquer the Holy Land following the capture of Jerusalem by the Ayyubid sultan Saladin in 1187. For this reason, the Third Crusade is also known as the Kings' Crusade. It was partially successful, recapturing the important cities of Acre and Jaffa, and reversing most of Saladin's conquests, but it failed to recapture Jerusalem, which was the major aim of the Crusade and its religious focus.
Mongol EmpireThe Mongol Empire of the 13th and 14th centuries was the largest contiguous land empire in history. Originating in present-day Mongolia in East Asia, the Mongol Empire at its height stretched from the Sea of Japan to parts of Eastern Europe, extending northward into parts of the Arctic; eastward and southward into parts of the Indian subcontinent, attempted invasions of Southeast Asia, and conquered the Iranian Plateau; and westward as far as the Levant and the Carpathian Mountains.
Teutonic OrderThe Teutonic Order is a Catholic religious institution founded as a military society 1190 in Acre, Kingdom of Jerusalem. The Order of Brothers of the German House of Saint Mary in Jerusalem was formed to aid Christians on their s to the Holy Land and to establish hospitals. Its members have commonly been known as the Teutonic Knights, having historically served as a crusading military order for supporting Catholic rule in the Holy Land and the forced conversion to Catholicism in the Baltics during the Middle Ages, as well as providing military protection for Catholics in Eastern Europe.
