The Attack on an Emigrant Train was painted during the height of westward expansion in the United States (1840s - 1860s) and is very much a product of its time. Its dramatic staging of two cultures clashing reinforced the doctrine of Manifest Destiny - the belief that European Americans had a right and even a Christian duty to expand throughout the North American continent. According to this theory, Indians were literally an obstruction in the path of American progress. Here they are portrayed as ferocious aggressors arresting the forward movement of the peaceful immigrants. The white man's steady aim of his gun - taken up to protect women and children who take shelter in the wagonsÑis contrasted with the chaotic mass of half-clothed warriors armed with simple weapons. Images such as this reinforced the prevailing notion of the Native American as primitive, even savage, and perpetuated the idea they were another element of the untamed landscape that needed to be subdued and civilized. Wimar's painting became enormously influential, inspiring and establishing a stereotype of attacks on wagon trains that persisted well into the twentieth century.
