USA HISTORY

Detailed explanation-1: -With its triumph in the Mexican-American War, the United States seemingly realized its Manifest Destiny by gaining an immense domain (more than 525, 000 square miles [1, 360, 000 square km] of land), including present-day Arizona, California, western Colorado, Nevada, New Mexico, Texas, and Utah.

Detailed explanation-2: -Expansionists such as Roosevelt, former President Harrison, and Captain Mahan argued for creating an American empire. However, others, including Grover Cleveland, Andrew Carnegie, and Mark Twain, opposed these ideas. Manifest Destiny became a disputed philosophy.

Detailed explanation-3: -Manifest Destiny, simply put, was the belief that Americans had the divine right to settle all throughout America, until the Pacific Ocean. This was caused by Americans feeling that it was the will of God that they tame the wilderness and civilize the west, and remake it in the image of the 13 colonies.
