Honestly, I'm not really joining in this nonsense but I thought I'd just throw this in -

The Crusades were military campaigns conducted under the sanction of the Latin 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.
