This chromolithograph by George A. Crofutt after the1872 painting of the same title by John Gast captured a view held by Americans in the mid 19th century:"Manifest Destiny". This was a belief that the United States had a God-given right to expand from the Atlantic Ocean to the Pacific Ocean. It shows settlers moving west protected by the spirit of Columbia (or the U.S.).
