The main causes of wars in the 20th century included nationalism, Imperialism, and ideological conflicts. Nationalist movements often led to tensions between nations and ethnic groups, while imperial ambitions fueled competition for colonies and resources. Additionally, the rise of ideologies such as fascism, communism, and militarism contributed to global conflicts, notably World War I and World War II. The Cold War further exemplified ideological divisions, leading to proxy wars and conflicts around the world.
