An Overview of the Crusades

Click on an entry to see the details.

  1. The religious and political background of the wars

    When the Seljuk Turks threatened the holy sites, including Jerusalem, as well as Byzantine territory in the late 11th century, the Byzantine emperor requested military support from Western Europe. In 1095, Pope Urban II called for the recapture of the Holy Land at the Council of Clermont, and the Crusades began as religious fervor combined with secular ambitions for territory and plunder.

  2. The First Crusade and the fall of Jerusalem (1099)

    The First Crusade, which set out in 1096, captured Jerusalem in 1099 after a series of battles, and established Crusader states in the region, including the Kingdom of Jerusalem. Great sacrifice accompanied this conquest, including the killing of many civilians during the takeover.

  3. Saladin and the Third Crusade

    Saladin, who unified the Islamic forces, recaptured Jerusalem after his victory at the Battle of Hattin in 1187, prompting the organization of the Third Crusade (1189–1192), led in part by Richard I of England. The two sides fought fiercely over Jerusalem, but Muslim rule ultimately continued, and Richard and Saladin agreed to a truce allowing Christian pilgrims to visit the holy sites.

  4. The number of major crusading expeditions

    The Crusades, which unfolded over roughly 200 years, are typically divided by historians into 8 or 9 expeditions, continuing from the First Crusade in 1096 to the fall of Acre β€” the Crusaders' final stronghold β€” in 1291. In particular, the Fourth Crusade of 1204 caused great controversy by sacking Constantinople, the capital of the Byzantine Empire β€” a fellow Christian nation β€” rather than the Islamic forces that had originally been its target.

  5. The Crusades' impact on East-West exchange

    The Crusades were a war that caused enormous loss of life, but they also became an opportunity to introduce Europe to the advanced scholarship and technology of the Islamic world, along with eastern goods like spices and silk. This exchange is also considered to have indirectly influenced the growth of Mediterranean trade among the Italian city-states and the advancement of scholarship during the Renaissance era.

Two hundred years of war entangled with religion and politics

The Crusades refer to a series of expeditions carried out over roughly 200 years, from 1096 to 1291, by Western European Christian forces attempting to reclaim the holy city of Jerusalem in the Middle East. This war, in which political and economic interests were intertwined alongside religious justification, left a deep mark on both medieval Europe and the Middle East.

The new ruler of Jerusalem after the Crusades

The vacuum left by the Byzantine Empire, weakened by the Crusades, was later filled by the power covered in our overview of the Ottoman Empire. Looking at the two eras together offers a better understanding of the shifting balance of power in the Middle East and Mediterranean region.
