How did European imperialism contribute to the start of world war 1
Imperialized territories entered war with their European Country to make it a full world war. Many European countries wanted to expand. - Hope this helps
first we should define what imperialism is. Imperialism is one of the 5 causes that would help in starting any ear( M.A.I.N; these are the 5 reasons that war erupts). Back before ww1 started, it was common for people to go around and dominate weaker nation; this is known as imperialism. As time continues, people were sick of being taking over by other stronger nations, so what they do is try to fight back and this is how it would contribute to any War including ww1 and ww2.
