After stopping the British Empire from expanding into the western frontier, Americans gained new confidence of strength and pride. Many of Americans started believing it was their destiny to control the western frontier and nothing could stop them. Through out the nineteenth century the U.S fought and negotiated with other countries and gained control over huge territories belonging to Spain, Mexico, France, Britain, and the American Indians. (Don Nardo. "The War Of 1812". San Diego, CA: Lucent Books. 1991 pg. 106). After all of the territory gained the country stretched from the Atlantic to the Pacific Ocean.  Westward expansion also created a demand to improve the nations roads and canals. With all the wealth from the weapons industry and territory gained in the 1800s helped the U.S eventually become a world power.
