What Motivates Soldiers To Participate In War?
Some people were overcome with a religious zeal which helped them stay motivated. The Crusaders, for instance, were assured by their clergy that their actions would be forgiven and they would go straight to paradise if they were to die in combat.
The desire of one nation to appropriate the riches of another is a common root cause of international conflict. Economic motivation is very frequently underpinning most hostilities too. Another thing that can motivate soldiers is their emotions toward their closest ones as it keeps them on high morale.
