"Westward Ho!" was the call of many a pioneer heading into the western United States from the country''s beginning. The insatiable desire for land that drove settlement westward is conveyed vividly by this collection of primary source documents. From the Monroe Doctrine to the end of the Spanish-American War with the Treaty of Paris, the documents and accompanying text provide rich context for a lively time in American history. Documents that detail the struggle of Native Americans provide a counterbalance to the ambitions of those who were convinced that the West was theirs by divine right.
