The Crusades were military campaigns sanctioned by the Latin Roman Catholic Church during the High Middle Ages through to the end of the Late Middle Ages. In 1095 Pope Urban II proclaimed the first crusade, with the stated goal of restoring Christian access to the holy places in and near Jerusalem. Many historians and some of those involved at the time, like Saint Bernard of Clairvaux, give equal precedence to other papal-sanctioned military campaigns undertaken for a variety of religious, economic, and political reasons, such as the Albigensian Crusade, the Aragonese Crusade, the Reconquista, and the Northern Crusades. Following the first crusade there was an intermittent 200-year struggle for control of the Holy Land, with six more major crusades and numerous minor ones. In 1291, the conflict ended in failure with the fall of the last Christian stronghold in the Holy Land at Acre, after which Roman Catholic Europe mounted no further coherent response in the east.
