The crusades are part of everyone's mental image of the Middle Ages. They extended, in one form or another, from the 11th to the 16th century. Those which reached the Holy Land were fought by men on horseback wearing metal armour and carrying lances and swords, as in the pictures. The onset of gunpowder had not yet spoiled the fun. They were truly international, in their own way emblematic of the myth of a single Christian European polity. They embodied everything that people associate with medieval warfare: reckless courage, murder, loot, adventure and romance.
