Wikimedia Commons has media related to Crusades.

The Crusades were a series of religious wars sanctioned by the Latin Church in the medieval period. The most commonly known Crusades are the campaigns in the Eastern Mediterranean aimed at recovering the Holy Land from Muslim rule, but the term "Crusades" is also applied to other church-sanctioned campaigns. These were fought for a variety of reasons including the suppression of paganism and heresy, the resolution of conflict among rival Roman Catholic groups, or for political and territorial advantage.
