Is it true that religion is the primary cause of wars in history?

This claim is among the most frequently repeated by the New Atheists—Dawkins, Hitchens, Harris—and circulates widely on social media. However, specialized historians see the picture as much more complex.

Inadequate Responses to Avoid

From some believers: "Religious wars aren't truly religious, but disguised political ones" is a harmful oversimplification. Some wars had a genuine religious dimension that cannot be denied. "True religions are always peaceful" ignores history—all major religions have witnessed violence in their name. "Religious violence is justified because it defends truth" is a dangerous position that justifies what we should be analyzing.

From some atheists: "Remove religion and wars disappear" is naive optimism—the 20th century witnessed the most horrific massacres at the hands of secular regimes (Stalin, Mao, Pol Pot). "Every war involving religion is a religious war" is confusion—the presence of religion doesn't mean it's the primary cause. "Religion makes people fanatically violent" is a generalization—billions of religious people live in peace.

What Do Serious Historical Studies Say?

First, the "Encyclopedia of Wars" by Charles Phillips and Alan Axelrod—the most comprehensive reference—documented 1,763 wars throughout recorded history. Of these, only 123 (7%) were classified as religious wars. Even if we double this number as a precaution, the overwhelming majority remain non-religious.

Second, analysis by the "Peace Research Institute Oslo" (PRIO): most contemporary wars are caused by natural resources, borders, political power, and nationalism. Religion is a secondary factor in most cases.

Third, historical casualty figures: World War I (17 million), World War II (70-85 million), the Great Chinese Famine (15-45 million), Stalinist purges (20 million)—all non-religious. Compared to: the Crusades (1-3 million over 200 years), European religious wars (3-11 million).

Fourth, the nature of alleged "religious wars": even wars classified as "religious" rarely have religion as their sole or primary cause. The Thirty Years' War (1618-1648)—which New Atheists cite as an example—began as a religious conflict but quickly transformed into a political struggle between European powers. Catholic France supported Protestants against Catholic Spain!

Serious Positions in Analyzing the Relationship

First, the "causal complexity" position (Karen Armstrong, William Cavanaugh): religion, politics, and economics are intertwined in most conflicts. Separating "religious cause" from others is artificial. The Israeli-Palestinian conflict: religious? nationalist? colonial? All of this and more.

Second, the "religion as identity" position (Jonathan Fox): religion is often an "identity marker" in ethnic/tribal conflicts more than a theological cause. Northern Ireland: Catholics and Protestants didn't fight over doctrine but over national identity and political rights.

Third, the "inherent human violence" position (René Girard): violence precedes religion. Religion is often an attempt to contain and regulate violence, not its cause. The sacred determines when violence is permitted and when it's forbidden.

Fourth, the "secular ideology as religion" position (John Gray): secular ideologies (nationalism, communism, Nazism) behaved like secular religions—absolute doctrines, martyrs, absolute enemies. If we expand the definition of "religion" to include these, the picture becomes more complex.

Counter-Historical Evidence

Religions have historically contributed to peace more than war. The "Pax Romana" under Christianity, "Dar al-Islam" that united warring peoples, religious movements against slavery, Gandhi and Martin Luther King Jr. Most charitable and humanitarian institutions worldwide have religious foundations.

Where We Stand in This Debate Today

The academic consensus is clear: religion is not the "primary cause" of wars historically. Political, economic, and ethnic factors are far more important. Yes, religion sometimes plays a role—as justification, as identity, as motivator—but reducing the complexity of human conflict to "religion is evil" is a harmful oversimplification. Intellectual honesty requires acknowledging the complexity of the phenomenon.
