Causes

Major wars usually grow from several pressures at once. Rival alliances, territorial disputes, economic competition, nationalism, insecurity, and failed negotiations can reinforce one another until leaders choose force.

Human Costs

Civilians often experience displacement, shortages, damaged schools and hospitals, family separation, and lasting psychological effects. These costs can continue long after formal fighting stops.

Aftermath

Peace agreements may redraw borders, create new institutions, assign responsibility, or launch rebuilding programs. Poorly designed settlements can also leave unresolved tensions.

Prevention

Diplomacy, communication, trade, treaties, international organizations, and conflict-resolution efforts can reduce risk. History shows that preventing escalation is often easier than ending a war once it begins.
