How did nationalism, new alliances, and growing tensions in Europe lead to World War I? Write your response in three to four complete sentences.

Alliances was the main reason

Explanation:

In the years leading up to the war, the nations of Europe were constantly jockeying for power and making alliances. Germany made an alliance with Austria-Hungary and Italy in 1881. These countries all agreed to protect each other in the event they were attacked by France. However, Italy then went and made a secret alliance with France saying they would not aide Germany.

It can cause intense competition among nations with each seeking to overpower the other.

Explanation:

The nationalism and patriotism of European nations, particularly the Great Powers, were significant factors in the road to World War I.
