Germany and other European nations invested in larger and more modern naval armaments. This is an example of what factor that led to World War I?
Militarism.
The factor that led to Germany and other European nations investing in larger and more modern naval armaments, which in turn contributed to the outbreak of World War I, is known as arms race.
To understand this factor, we need to examine the historical context of the time. Prior to World War I, Europe was experiencing a period of intense competition and rivalry between nations, particularly Germany and Great Britain. The naval arms race refers to the competition between these two powers to build and expand their navies.
To get an answer to this question, you could read about the events leading up to World War I, particularly the tensions and rivalries among European powers. You could also study the naval arms race specifically, looking at the naval policies and advancements made by Germany and other European nations.
By researching the naval arms race, you would discover that Germany, under Kaiser Wilhelm II, sought to challenge the naval supremacy of Great Britain by expanding its own navy, the Imperial German Navy. This decision was driven by Germany's desire for global power and influence, as well as the belief that a strong navy was crucial for maintaining a powerful position in the world.
As Germany began building more and more naval armaments, it alarmed other European nations, particularly Great Britain, which relied heavily on its naval dominance to protect its vast overseas territories. In response, these nations also began investing in their navies, creating an intensifying arms race.
The naval build-up increased the tension and suspicion among European powers, escalating the possibility of conflict. The growing naval power of Germany threatened the relatively peaceful balance of power in Europe, as it challenged the dominance of Great Britain. This, along with other underlying political, economic, and territorial issues, eventually led to the eruption of World War I in 1914.
