The Crusades may have influenced the trade routes shown on this map as crusading led to the conquest and colonization of many islands, which arguably helped ensure Christian control of Mediterranean trade routes (at least for as long as the islands were held). Crusading also played a role in the conquest of the Iberian peninsula.
The Crusades were a series of religious wars initiated, supported, and sometimes directed by the Latin Church in the medieval period. The best known of these Crusades are those to the Holy Land in the period between 1095 and 1291 that were intended to recover Jerusalem and its surrounding area from Islamic rule.
The Mediterranean trade route was a great source for trading wealth. The Mediterranean Sea is located at the center of three continents so it is efficient for trade. It was connected to the silk roads in the east and was used to transport goods from Asia throughout Europe.
Spain and Portugal occupy the Iberian Peninsula, which is separated at its southern tip from North Africa by only a narrow strait situated at the juncture of the Mediterranean and the Atlantic. This key geographical position played an important part in Iberia's history.
