Before the American Civil War (1861–65), the idea of Manifest Destiny was used to validate continental acquisitions in the Oregon Country, Texas, New Mexico, and California. The purchase of Alaska after the Civil War briefly revived the concept of Manifest Destiny, but it most evidently became a renewed force in U.S. foreign policy in the 1890s, when the country went to war with Spain, annexed Hawaii, and laid plans for an isthmian canal across Central America.
