Final answer:

Step-by-step explanation:
Imperialism became more popular in the United States by the end of the 19th century for a few reasons:
- Americans wanted to sell goods to new markets and buy raw materials for new industries. The United States had experienced rapid industrialization and needed new markets to sell its products. Expansion into other countries provided access to these markets and the resources needed for industrial growth.
- Americans feared imperialism would bring the United States into conflict with other powers. The great empires of Europe were expanding and acquiring territories around the world. The United States wanted to prevent being left behind and saw imperialism as a way to protect its interests and maintain its status as a world power.
- American exceptionalism and the desire to spread liberty and democracy. Some Americans believed it was their duty to spread their ideals of liberty and democracy to other nations. They saw imperialism as an opportunity to extend American influence and promote democratic principles.
