Unit 4: Nationalism, Industrialism, and Imperialism

Lesson A: Birth of the Imperial World

Review and Assessment


From the 18th through the 20th centuries, Westerners practiced imperialism in many areas of the world. The original motive for this imperialism was to secure natural resources. Other motives, such as nationalism, played a role in the development of this later imperialism. The early birth of imperialism laid the foundation for over 100 years of imperialist rule and eventual international conflict over colonies.
