Answer:
Many died in war.
Step-by-step explanation:
Kings, knights, and commoners from West Europe summoned to fight for Christianity. The Crusades lasted for years where Christians tried to gain their Holy Land in the Middle East and stop Muslim from expanding its territories. One of the consequences was that Christians lost the war because they were tired of the long journey and fight against the Muslims. To reach the Middle East, Europeans had to walk a long way by foot in the dry climate.
