Manifest Destiny is when a country or countries expand their rulings on freedom and democracy over other foreign countries. They do this because that country feels that if they don't spread their rulings over foreign countries that they will not make any profit and benefit from it. Another well known country will spread their rulings, and they will be the "big cheese" in the “game” because they will be making the money and profiti g from the land. An example of Manifest Destiny is when the United States tried to spread their rulings over North America towards the Pacific Ocean.
"We need Hawaii just as much and a good deal more than we did California. It is Manifest Destiny."
--William McKinley (25th President of USA (1896-1901)
