County of EdessaThe County of Edessa (Latin: Comitatus Edessanus) was a 12th-century Crusader state in Upper Mesopotamia. Its seat was the city of Edessa (modern Şanlıurfa, Turkey). In the late Byzantine period, Edessa became the centre of intellectual life within the Syriac Orthodox Church. As such it also became the centre for the translation of Ancient Greek philosophy into Syriac, which provided a stepping stone for the subsequent translations into Arabic. When the Crusades arrived, it was still important enough to tempt a side-expedition after the siege of Antioch.
EdessaEdessa (ɪˈdɛsə, ; Édessa) was an ancient city (polis) in Upper Mesopotamia, founded during the Hellenistic period by King Seleucus I Nicator (305-281), founder of the Seleucid Empire. It later became capital of the Kingdom of Osroene, and continued as capital of the Roman province of Osroene. In Late Antiquity, it became a prominent center of Christian learning and seat of the Catechetical School of Edessa. During the Crusades, it was the capital of the County of Edessa.
Second CrusadeThe Second Crusade (1145–1149) was the second major crusade launched from Europe. The Second Crusade was started in response to the fall of the County of Edessa in 1144 to the forces of Zengi. The county had been founded during the First Crusade (1096–1099) by King Baldwin I of Jerusalem in 1098. While it was the first Crusader state to be founded, it was also the first to fall. The Second Crusade was announced by Pope Eugene III, and was the first of the crusades to be led by European kings, namely Louis VII of France and Conrad III of Germany, with help from a number of other European nobles.
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.
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.
