Why was imperialism a cause of world war 1?

Imperialism contributed to World War I by intensifying rivalries among European powers as nations competed for colonies and resources, leading to heightened tensions. The scramble for territories, particularly in Africa and Asia, created friction and distrust, particularly between major powers like Britain, France, and Germany. Additionally, imperial ambitions fueled militarism and alliances, as countries sought to protect their interests and assert dominance, ultimately culminating in a complex web of entangled alliances that ignited the war.
