The Political and Economic Geography of Southern Secession

Abstract

We study the economic and political determinants of the Southern secession movement of 1860/61. While economic historians emphasize the importance of slavery to the South’s economy as the primary factor behind the movement, we demonstrate the important role that political inequality among whites played in facilitating secession. In particular, secession was decided in state conventions, which allowed secessionists to exploit biases to representation and may have been pivotal in Alabama and Georgia. Our results suggest that the region’s investment in slavery alone may not be sufficient to explain the electoral success of the movement in the largest Lower South states.
