Endogenous growth theories suggest that market integration will be more conducive to economic development when the previously isolated regions have large stocks of human capital. This paper uses the level of per capita patenting in nineteenth-century Virginia to measure this human capital. By the end of the 1870s, the rail network of the Old Dominion was rapidly being integrated with the rest of the nation. Inventiveness spread throughout northern Virginia, but the former plantation areas of the state fell behind.
