Final answer:
Secret Alliances, Imperialism, and National pride were all causes that contributed to the start of World War 1.
Step-by-step explanation:
Secret Alliances was one of the causes that contributed to the start of World War 1. European nations formed various secret alliances, such as the Triple Entente and the Central Powers, in an effort to protect their interests and maintain a balance of power. These alliances created a complex network of commitments that pulled countries into the war when one of their allies was attacked.
Imperialism was another cause. European nations competed for colonies and resources around the world, leading to tensions and rivalries between them. As these rivalries intensified, so did the likelihood of conflict.
National pride was also a contributing factor. Many nations had a strong sense of patriotism and believed in the superiority of their own country. This led to increased militarism and a desire to defend one's nation at all costs.
