American local history has been much studied, but rarely integrated into the general history of the country. Although greater attention is now being paid to the connexions between local political, social and economic developments and national trends, there is still a very real disparity in historiographical emphasis between national issues and the problems of community life experienced by Americans in the past. For no period, perhaps, is this disparity so graphic as for the mid-nineteenth century; the years from about 1840 to the 1870s or the 1880s were convulsed by sectional rivalries, civil war and reconstruction, to which matters historians have devoted their attention. Steadily, however, the local communities themselves have come under scrutiny. But the major interpretation currently accepted reinforces, rather than qualifies, the general picture we have of that period, since the North, at least, is regarded as buoyant and expansive in the mid-century, pursuing with relentless self-confidence such aims as help to explain the coming, and the winning, of the Civil War; reform, moral and educational improvement, and the opening of economic opportunities to yeomen farmers, artisans and small merchants.
