Why did Medieval society suffer from constant conflict?

Medieval society suffered from constant conflict due to a combination of factors, including feudalism, which created a fragmented political structure with numerous lords competing for power and resources. The lack of centralized authority often led to local disputes escalating into larger conflicts. Additionally, religious tensions, particularly the Crusades, and external threats from invading forces contributed to a climate of instability and warfare. Social and economic inequalities further fueled strife among different classes and regions.
