One of the aims of this book has been the attempt to re-evaluate the regime of Porfirio Diaz in the light of new research and of changing historiographical fashion. Above all, it has sought to liberate the interpretation of the Diaz era from the distorting perspective of the subsequent Revolution. The concentration in Revolutionary historiography on the regime's rapidly fading fortunes after 1908 has, inevitably, accentuated its frailties and failures and has distorted the analysis of its achievements.
