This growing digital archive provides transcriptions of thousands of newspaper articles related to the Mexican-American War of 1846-48. The articles are drawn from five newspapers: The Times of London, England; Niles’ National Register of Baltimore, Maryland; the Richmond Whig and Daily Advertiser and the Richmond Enquirer of Richmond, Virginia; and the Martinsburg Gazette of Martinsburg, Virginia (now West Virginia). They include opinion pieces, more straightforward reporting, published U.S. and Mexican government documents, and reprinted items from other newspapers, spanning the period from 1845, when the United States annexed Texas, through 1848, when Mexico surrendered and the Treaty of Guadalupe Hidalgo was signed. Especially useful for students of world history, this selection enables comparisons of the responses to the war in England and in the United States. Articles can be browsed easily by date and title, and since all of the transcriptions from each newspaper appear on a single webpage, keyword searches are also easy. Finally, the home page contains links to related images and documents housed on other websites.
