Several faiths emphasize peace and non-violence as core tenets, and based on historical analyses, some have no record of initiating or participating in wars in the name of their religion. However, it’s important to note that no large-scale religion is entirely free from all forms of conflict or individual adherents’ actions, as human factors like politics or self-defense can intersect. Below, I’ll name key examples that fit your criteria closely, drawing from scholarly and discussion-based sources. These are primarily smaller or minority faiths, as major world religions often have complex histories involving violence despite peaceful claims.

Jainism

Jainism, an ancient Indian religion, centers on ahimsa (non-violence) toward all living beings, claiming to be a path of ultimate peace and compassion. It has no history of wars fought in its name, with adherents historically avoiding warfare and focusing on trade and asceticism instead. 13 4 21 While some individual Jains have participated in battles throughout history (often in defensive or secular roles), the faith itself has never endorsed or sparked religious conflicts. 19 20

Bahá’í Faith

The Bahá’í Faith, founded in the 19th century, explicitly promotes world peace, unity among religions, and the elimination of war as central teachings. It has no history of involvement in any wars, with its principles forbidding partisan politics, military combat roles, and holy wars. 24 25 26 Adherents are encouraged to serve in non-combative capacities if required by law, but the faith has remained neutral in global conflicts. 27 28

Quakers (Society of Friends)

Quakers, a Christian denomination originating in the 17th century, claim peace as a fundamental “testimony,” opposing all forms of violence and war. They have no history of wars in their name, with a long tradition of pacifism, conscientious objection to military service, and activism against conflict. 14 16 However, some historical involvement in non-violent but harmful actions, like running assimilationist boarding schools for Indigenous peoples, has been critiqued as cultural violence.

Jehovah’s Witnesses

This Christian group teaches that true faith involves neutrality in worldly conflicts and claims to follow Jesus’ example of peace. They have no history of participating in wars, refusing military service and remaining apolitical, even under persecution. 10 16 Their stance has led to legal battles for conscientious objection rights worldwide.

Mennonites and Amish

These Anabaptist Christian groups emphasize pacifism and non-resistance, claiming to live by Jesus’ teachings on turning the other cheek and loving enemies. They have no history of wars, historically migrating to avoid conscription and focusing on communal, non-violent living. 10 16 Like Quakers, they prioritize peace but have faced criticism for isolationism.

Other minor faiths sometimes mentioned in discussions include the Church of the Brethren, Christadelphians, and Unitarian Universalists, which share pacifist leanings without war histories, though they are often subsets of broader traditions. 16 1 In contrast, larger religions like Buddhism, Hinduism, Christianity (mainstream), and Islam claim peaceful ideals but have documented histories of wars or violence, often intertwined with political or cultural factors. 1 11
