Frederick Jackson Turner

In the present volume I have kept before myself the importance of regarding American development as the outcome of economic and social as well as political forces. To make plain the attitude and influence of New England, the middle region, the south, and the west, and of the public men who reflected the changing conditions of those sections in the period under consideration, has been my principal purpose.

(1825-1829)

The history of the United States is the history of a growing nation. Every period of its life is a transitional period, but that from the close of the War of 1812 to the election of Andrew Jackson was peculiarly one of readjustment. It was during this time that the new republic gave clear evidence that it was throwing off the last remnants of colonial dependence. The Revolution had not fully severed the United States from the European state system; but now the United States attained complete independence and asserted its predominance in the western continent.
