The Crusades were a series of military campaigns commonly supported by religious motives carried out by much of Christian Latin Europe, in particular, by the Franks of France and the Holy Roman Empire. Crusades with the specific goal of reestablishing Christian control of the Holy Land were fought over a period of nearly 200 years, between 1095 and 1291.
Other campaigns in Spain and in Eastern Europe continued until the fifteenth century. The crusades were held mainly against the Muslims, although several campaigns were also made against the pagan Slavs, Jews, Greek and Russian Orthodox Christians, the Mongols, the Cathars, Hussites, Waldensians, Prussians, and mainly the political enemies of the popes. . Crusaders took vows and were granted penance for past sins, often called an indulgence.
