Concept note-1: -Both a desire for new markets for its industrial products and a belief in the racial and cultural superiority of Americans motivated the United States’ imperial mission.
Concept note-2: -Because the Industrial Revolution increased the production capacity of Western states astronomically, there was an enormous hunger for raw materials to satisfy demands.
