During the eighteenth century the Bajio emerged from its frontier
condition to become the pace-maker of the Mexican economy. Silver mining
boomed and population increased rapidly. It is the aim of this book to
examine the impact of these dramatic changes on the structure of
agricultural production and the pattern of rural society. In his Miners
and Merchants in Bourbon Mexico 1763-1810 (Cambridge Latin American
Studies 10) Dr Grading demonstrated how the local entrepreneurial elite
accumulated vast fortunes during the mining bonanza at Guanajuato. In
this present work he describes how many of the same men invested their
capital in the purchase and improvement of haciendas in the nearby
district of Leon. The countryside was transformed as wasteland was
cleared for ploughing, or was irrigated.
