Analytical yet lively, mixing political and cultural history, Mexico in the 1940s captures the humor, passion, and significance of Mexico during the World War II and post-war years when Mexicans entered the era called "the miracle" because of the nation's economic growth and political stability. Niblo develops the case that the Mexico of today -- politically and executively centralized, stressing business and industry, corrupt, ignoring the needs of the majority of the population -- has its roots in the decade and a half after 1940.

Finally, Mexico in the 1940s offers a unique interpretation of Mexican domestic politics in this period, including an explanation of how political leaders were able to reverse the course of the Mexican Revolution in the 1940s; an original interpretation of corruption in Mexican political life, a phenomenon that did not end in the 1940s; and an analysis of the relationship between the U.S. media interests, the Mexican state and the Mexican media companies that still dominate mass communication today.
