what is an event that falls in Nationalism, competition for territory, military rivalry, and alliance

The event that falls under Nationalism, competition for territory, military rivalry, and alliance is World War I.

Here's a step-by-step explanation:

1. Nationalism: This was a major factor in the cause of World War I. Many countries, especially those in Europe, were proud of their heritage and culture. This pride often turned into a desire for their nation to be superior to others, leading to conflicts.

2. Competition for Territory: Many countries were expanding their empires and looking for new territories to conquer. This led to disputes and conflicts over who had the right to certain lands. For example, the conflict between France and Germany over Alsace-Lorraine.

3. Military Rivalry: The nations involved in World War I were building up their military forces, creating a sense of fear and suspicion. The arms race, particularly between Germany and Great Britain, increased tensions.

4. Alliance: The system of alliances that were formed between different countries also contributed to the start of World War I. These alliances promised mutual defense, meaning that if one country was attacked, its allies would come to its defense. This led to a domino effect, pulling many countries into the war.

So, World War I is a prime example of an event that involved nationalism, competition for territory, military rivalry, and alliances.
