What is Manifest Destiny?
The idea that God has predestined the United States to spread democracy and capitalism throughout all of North America is known as "Manifest Destiny," and it was first used in 1845.
Prior to the 19th century, westward travel had been a top objective for Americans. The English were keen to settle the vast wilderness to the west as soon as they landed in North America. As a result of U.S. President Thomas Jefferson's 1803 Louisiana Purchase, which almost doubled the size of the country, many sought to migrate west.
