During the Second Crusade (1147-1149), Jerusalem was not captured; in fact, it was already under Christian control, having been taken during the First Crusade in 1099. The Second Crusade aimed to respond to the fall of the County of Edessa in 1144 to Muslim forces. The crusaders, led by figures such as King Louis VII of France and Emperor Conrad III of Germany, faced significant challenges, and their campaign ultimately ended in failure, leading to no significant gains in the Holy Land.

There were many wars, sometimes about land disputes or something, but the main wars were the Crusades. The Christians wanted control of the Holy City of Jerusalem, but the Muslims controlled it. Both sides wanted it for religious reasons. The Muslims were fine letting the Christians come to Jerusalem and worship, but the Christians wanted it all to themselves. For over two hundred years the Christians fought with the Muslims over the control of the city.
The emperor who requested aid during the Crusades was Emperor Alexios I Komnenos of the Byzantine Empire. In 1095, facing increasing pressure from the Seljuk Turks and the loss of large parts of Asia Minor, Emperor Alexios sent an appeal to Pope Urban II for military assistance. This request for help led to the First Crusade (1096–1099). At the Council of Clermont in November 1095, Pope Urban II responded to Alexios' call by urging Western Christians to take up arms and embark on a military campaign to liberate Jerusalem from Muslim control and to assist the Byzantine Empire in regaining its lost territories. Urban's call for a crusade galvanized the Christian knights and peasants of Western Europe, ultimately leading to the launch of the First Crusade. While Alexios sought help primarily to defend his empire, the Crusade also evolved into a religious mission to reclaim Jerusalem, and the Byzantine Empire's relationship with the crusaders became increasingly complex in the years that followed.
The events that occurred during the partition of Bengal were the separation of the Muslims and Hindus and the establishment of factories in east Bengal. Formation of the political affiliations based on the Muslims and Hindus are the other events that occurred during the partition of Bengal.
Christian knights hoped to recapture Jerusalem from the Muslims during the Crusades. The city of Jerusalem held great religious significance to Christians as the site of Jesus Christ's crucifixion and resurrection.
Saladin, the Sultan of Egypt and Syria, is the great Muslim leader known for retaking Jerusalem from the Christians during the Third Crusade in 1187. His victory at the Battle of Hattin paved the way for the recapture of Jerusalem after nearly 90 years of Christian control.
they captured and invaded Jerusalem in 1076 and it lasted till 2099, when the crusaders took over.
During the second crusades Muslims managed to defeat the Christians and retake Jerusalem. I'd like to add that a "crusader" is a warrior taking part in a crusade, while the "wholly wars" started by the Mediaeval Christians were called "crusades".

Jerusalem was one of the cities gained during the First Crusade but that is all I know.
The Crusaders attacked Jerusalem during the First Crusade in 1099 with the goal of reclaiming the city from Muslim control. They saw it as a holy mission to recapture the city where Jesus had lived and died. The capture of Jerusalem was a key objective in the Crusader's efforts to secure Christian control over important religious sites in the region.
In the first crusade they fought over and through Jerusalem. After capturing it from the Muslims, the crusaders established some counties and other minor areas.
The Crusades were initiated by Christians to recapture the Holy Land (Jerusalem) from Muslims, so Christians had the home field advantage in that region. However, Muslims also had home field advantage in the sense that they were defending their land.
During the 1100s, Jerusalem was primarily under the control of the Crusaders following the First Crusade in 1099. The Crusaders established the Kingdom of Jerusalem, which became a significant Christian stronghold in the region. However, Muslim forces, particularly under the leadership of figures like Zengi and later Saladin, began to challenge Crusader control, culminating in the recapture of Jerusalem by Saladin in 1187.
The Crusades were a series of holy wars fought between Christians and Muslims for control of Jerusalem and the Holy Land during the Middle Ages. The First Crusade was launched in 1096 and resulted in the capture of Jerusalem by Christian forces in 1099. Subsequent Crusades followed over the span of two centuries.
It was during the Second Crusade in 1144.
