2. Imperial Reach: The war involved the territorial possessions and colonial empires of the European powers. Many battles were fought in various regions of Africa, Asia, and the Middle East, where European powers had colonized and established spheres of influence.

These alliances involved nations on different continents, creating a web of connections that drew countries from around the world into the conflict.
4. Economic and Resource Impact: The war had significant economic consequences that reached far beyond Europe. It disrupted trade routes, led to shortages of goods and resources, and triggered an international economic crisis. The war also stimulated the growth of industries and economies in non-European countries, which contributed to shifting global economic power.
5. Human and Social Impact: The human cost of World War I was felt globally. Millions of soldiers and civilians from various countries lost their lives, and countless more were injured or displaced.
