The text authors refer to a “neo-Hamiltonian” economic policy adopted by Republicans after the War of 1812. Explain why the Republicans, who had earlier detested Hamilton and his policies, adopted these same policies.

What will be an ideal response?

ANSWER
Consider: lessons from the War of 1812 (tariff to protect new manufacturers, national bank to assure national government credit, etc.); Westward expansion (demand for internal improvements, cheap land); Postwar national pride (national interests supersede sectional interests)
