Second Crusade (1147–1149)

The Second Crusade (1147–1149) was the second major crusade launched from Europe as a Catholic ('Latin') holy war against Islam. 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 of Boulogne 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 FranceThe Kingdom of France is the historiographical name or umbrella term given to various political entities of France in the medieval and early modern period. It was one of the most powerful states in Europe since the High Middle Ages. It was also an early colonial power, with possessions around the world. Colonial conflicts with Great Britain led to the loss of much of its North American holdings by 1763. The Kingdom of France adopted a written constitution in 1791, but the Kingdom was abolished a year later and replaced with the First French Republic.France and Conrad III of Germany, with help from a number of other European nobles. The armies of the two kings marched separately across Europe. After crossing Byzantine territory into Anatolia, both armies were separately defeated by the Seljuk Turks. The main Western Christian source, Odo of Deuil, and Syriac Christian sources claim that the ByzantineThe Byzantine Empire, also referred to as the Eastern Roman Empire or Byzantium, was the continuation of the Roman Empire primarily in its eastern provinces during Late Antiquity and the Middle Ages, when its capital city was Constantinople. It survived the fragmentation and fall of the Western Roman Empire in the 5th century AD and continued to exist for an additional thousand years until the fall of Constantinople to the Ottoman Empire in 1453.Byzantine Emperor Manuel I Komnenos secretly hindered the crusaders' progress particularly in Anatolia, where he is alleged to have deliberately ordered Turks to attack them. Louis and Conrad and the remnants of their armies reached Jerusalem and participated in 1148 in an ill-advised attack on Damascus. The crusade in the east was a failure for the crusaders and a great victory for the Muslims. It would ultimately have a key influence on the fall of Jerusalem and give rise to the Third Crusade at the end of the 12th century.

The only significant Christian success of the Second Crusade came to a combined force of 13,000 Flemish, Frisian, Norman, EnglishThe Kingdom of England was a sovereign state on the island of Great Britain from about 927, when it emerged from various Anglo-Saxon kingdoms, until 1 May 1707, when it united with Scotland to form the Kingdom of Great Britain. The Viking invasions of the 9th century upset the balance of power between the English kingdoms, and native Anglo-Saxon life in general. The English lands were unified in the 10th century in a reconquest completed by King Æthelstan in 927.English, Scottish, and German crusaders in 1147. Travelling from England, by ship, to the Holy Land, the army stopped and helped the smaller (7,000) Portuguese army in the capture of Lisbon, expelling its Moorish occupants.

  Second Crusade (1147–1149)

  The Second Crusade (1147–1149) was the second major crusade launched from Europe as a Catholic ('Latin') holy war against Islam. The Second Crusade was started in response to the fall of the County of Edessa in 1144 to the forces of Zengi.

  Background: the fall of Edessa: After the First Crusade and the minor Crusade of 1101, there were three crusader states established in the east: the Kingdom of Jerusalem, the Principality of Antioch and the County of Edessa.

  Saint Bernard of Clairvaux: The Pope commissioned French abbot Bernard of Clairvaux to preach the Second Crusade, and granted the same indulgences for it which Pope Urban II had accorded to the First Crusade.

  Wendish Crusade: By the end of the crusade, the countryside of Mecklenburg and Pomerania was plundered and depopulated with much bloodshed, especially by the troops of Henry the Lion.

  Reconquista and the fall of Lisbon: The crusaders agreed to help the King attack Lisbon, with a solemn agreement that offered to them the pillage of the city's goods and the ransom money for expected prisoners.

  Forces: The German contingent comprised about 2,000 knights; the French contingent had about 700 knights from the king’s lands while the nobility raised smaller numbers of knights; and the Kingdom of Jerusalem had about 550 knights and 6,000 infantrymen.

  Crusade in the East: The Germans had already decided to travel overland through Hungary, as the sea route was politically impractical because Roger II of Sicily was an enemy of Conrad. Many of the French nobles distrusted the land route, which would take them through the Byzantine Empire, the reputation of which still suffered from the accounts of the First Crusaders.

  Aftermath: Each of the Christian forces felt betrayed by the other. A new plan was made to attack Ascalon and Conrad took his troops there, but no further help arrived, due to the lack of trust that had resulted from the failed siege.
