In the mid-nineteenth century, Horace Greeley's New-York Tribune had the largest national circulation of any newspaper in the United States. Its contributors included many of the leading minds of the period-Margaret Fuller, Henry James Sr., Charles Dana, and Karl Marx. The Tribune was also a locus of social democratic thought that closely matched the ideology of Greeley, its founder and editor, who was a noted figure in politics and reform movements.
