Beginnings Of The American People By Carl Lotus Becker 1915]. The purpose of this volume is to show the action and reaction of the most important social, economic, political, and personal forces that have entered into the make-up of the United States as a nation. The primary assumption of the author is that the people of this country did not compose a nation until after the close of the Civil War in 1865. Of scarcely less importance is the fact that the decisive motive behind the different groups in Congress at every great crisis of the period under discussion was sectional advantage or even sectional aggrandizement. If Webster ceased to be a particularist after 1824 and became a nationalist before 1830, it was because the interests of New England had undergone a similar change; or, if Calhoun deserted about the same time the cause of nationalism and became the most ardent of sectionalists, it was also because the interests of his constituents, the cotton and tobacco planters of the South, had become identified with particularism, that is. States rights.
