His publications during the next few years demonstrated an exploration of the associations between imperialism and international conflict. These works included "War in South Africa" (1900) and "Psychology of Jingoism" (1901). In what is arguably his magnum opus, "Imperialism" (1902), he espoused the opinion that imperial expansion is driven by a search for new markets and investment opportunities overseas. "Imperialism" gained Hobson an international reputation, and influenced such notable thinkers as Vladimir Lenin and Leon Trotsky, and Hannah Arendt's "The Origins of Totalitarianism" (1951).
