Final answer:
Crusaders are identified by the red crosses on their backs, distinct armor, helmets, and the weapons they carry, such as shields and spears, as well as their horses in historical paintings and artifacts.
Step-by-step explanation:
The Crusaders are identified in paintings and tapestries from the era of the First Crusade by several distinguishing features.
One of the most iconic symbols used to identify the Crusaders is the red crosses emblazoned on their outfits. In the context of historical artifacts, such as the Bayeux Tapestry or relief carvings, Crusaders are often depicted wearing specific types of armor, helmets, carrying shields, spears, and other weapons.
Their horses, though not typically armored, also served as a significant identifier in the imagery.
The Crusaders established several Crusader States, which were often called Outremer, and during the various Crusades, they fought to secure control over Jerusalem and other significant cities.
Visual documentation such as the Bayeux Tapestry, sculptures, and relics like the Crown of Thorns also serve as historical evidence of the Crusades and the intercultural exchanges between Christian and Islamic worlds during that era.
