^Lind, Michael: "Lincoln and his successors in the Republican party of 1865–1932, by presiding over the industrialization of the United States, foreclosed the option that the United States would remain a rural society with an agrarian economy, as so many Jeffersonians had hoped." and "...Hamiltonian side ... the Federalists; the National Republicans; the Whigs, the Republicans; the Progressives." — "Hamilton's Republic" Introduction pp. xiv–xv.

^Lind, Michael: "During the nineteenth century the dominant school of American political economy was the "American School" of developmental economic nationalism ... The patron saint of the American School was Alexander Hamilton, whose Report on Manufactures (1791) had called for federal government activism in sponsoring infrastructure development and industrialization behind tariff walls that would keep out British manufactured goods ... The American School, elaborated in the nineteenth century by economists like Henry Carey (who advised President Lincoln), inspired the "American System" of Henry Clay and the protectionist import-substitution policies of Lincoln and his successors in the Republican party well into the twentieth century." — "Hamilton's Republic" Part III "The American School of National Economy" pp. 229–30. Free Press, Simon & Schuster: 1997. ISBN0-684-83160-0.
^Richardson, Heather Cox: "By 1865, the Republicans had developed a series of high tariffs and taxes that reflected the economic theories of Carey and Wayland and were designed to strengthen and benefit all parts of the American economy, raising the standard of living for everyone. As a Republican concluded ... "Congress must shape its legislation as to incidentally aid all branches of industry, render the people prosperous, and enable them to pay taxes ... for ordinary expenses of Government." — "The Greatest Nation of the Earth" Chapter 4, "Directing the Legislation of the Country to the Improvement of the Country: Tariff and Tax Legislation" pp. 136–37.

^Boritt, Gabor S: "Lincoln thus had the pleasure of signing into law much of the program he had worked for through the better part of his political life. And this, as Leonard P. Curry, the historian of the legislation has aptly written, amounted to a "blueprint for modern America." and "The man Lincoln selected for the sensitive position of Secretary of the Treasury, Salmon P. Chase, was an ex-Democrat, but of the moderate variety on economics, one whom Joseph Dorfman could even describe as 'a good Hamiltonian, and a western progressive of the Lincoln stamp in everything from a tariff to a national bank.'" — "Lincoln and the Economics of the American Dream" Chapter 14, "The Whig in the White House" pp. 196–97.

^Howe, Daniel Walker "The policies of tariff protection, federally sponsored internal improvements, and national banking that were later to be known as the “American System” took coherent shape in the years between 1816 and 1828 and were coherent with the “national” wing of the Republican party." - "The Political Culture of the American Whigs, pp. 48-49.
