Horace Greeley’s most famous legacy was probably his injunction to “Go West, Young Man!” Millions did, of course. Whether or not Greeley ever said these exact words, generations of school children recited or remembered them. Westward expansion in search of land and freedom constituted one of the major trends in American history. Greeley both articulated and reflected that trend. But he also fused European and American ideas of freedom into a single republican philosophy grounded in free labor and the right to rise or fall by dint of one’s own hard work.
