Some of the countries in Europe that were strong supporters of militarism during the early 20th century included Germany, Austria-Hungary, and Italy. These countries were characterized by their aggressive foreign policies and their belief in the superiority of their military forces.
These countries spent a significant amount of money on building up their military capabilities, including the development of new weapons and the expansion of their armed forces. They also invested heavily in colonial expansion, establishing and maintaining colonies in Africa, Asia, and the Americas.
The process of colonizing had a number of effects on these countries. For one, it allowed them to gain access to new resources and markets, which helped to fuel their industrialization and economic growth. It also allowed them to expand their influence and assert their dominance over other nations. However, the costs of maintaining colonies and the tensions that often arose between colonizers and colonized peoples also contributed to the destabilization of these countries and contributed to the outbreak of World War I.
