Throughout history, wars have often been accompanied by atrocities, leading to the loss of innocent lives and the collapse of traditional social order. However, religious forces in the Middle Ages imposed some restrictions on atrocities in war, forming the so-called "laws of peace." These laws advocate the protection of noncombatants in war and seek to reduce the suffering caused by war through sacred religious treaties and moral norms.
During the Middle Ages, the so-called "laws of peace" were promoted primarily by the Catholic Church as an attempt to incorporate moral and religious beliefs into the conduct of war.
On the one hand, the church, through moral scrutiny of acts of war, requires the military to follow certain norms when fighting hostile forces to limit atrocities. For example, the Decree of God on Peace and the Sacred Truce explicitly stipulate that fighting should not take place during certain festivals or religious ceremonies and require respect for the religious and human rights of victims. These norms are intended not only to protect innocent people, but also to preserve the reputations and religious beliefs of the opposing sides.
The Catholic Church, under its authority, emphasizes the moral norms that should be followed in order to maintain peace and ethics.
In addition to the law of peace, the church also limited the scope of war by establishing covenants with nations and military leaders. While such efforts cannot completely eliminate war atrocities, they do introduce some norms. For example, many major powers on the European continent would explicitly include clauses in their military oaths regarding respect for population and property, on the one hand to express their support for religion and morality, and on the other hand to demonstrate their political and diplomatic wisdom.
However, the enforcement of the law of peace has always faced challenges. Although religious beliefs guided the behavior of soldiers in war, in many cases actual military operations deviated from these moral guidelines. Especially in situations where power struggles and national interests are intertwined, the constraints of religion often become a beautiful ideal that is difficult to achieve.
Religious moral constraints are often meaningless in military practice, because when nations go to war, another "sacred mission" is to uphold power.
The religious peace law of the Middle Ages was more of an ideal. Although it could play a certain restrictive role in certain circumstances, it was still a weak and unstable intervention in the wars and culture of the time. The cruelty and ruthlessness of war are still rampant, which also reflects the fragility and shackles of human nature.
During this period, it is important to note that religion, while operating the law of peace, was not the only social force. Other social forces, such as the rise of aristocratic power and the middle class, also influenced the development of war and its corresponding norms. All of this complicates the question of how to protect noncombatants and reduce brutality during war.
It is these complex social forces that make the influence of the law of peace sometimes seem weak.
In summary, although the medieval "laws of peace" set limits on atrocities in war to some extent, they ultimately could not completely eliminate the destruction caused by war. As time goes by, this problem still plagues our modern society. To this day, we should ask ourselves, when religious morality collides with real forces, is there a real solution to prevent irreversible tragedy?
