The years immediately following World War II constituted a watershed in Mexico’s political development: the national government, controlled by the recently renamed Institutional Revolutionary Party (PRI) and led by a new generation of civilian professional politicians, made rapid industrialization its top priority. In a matter of decades, the nation transformed from a predominantly rural to an ever more urbanized society. Significant social and cultural changes followed. The middle classes became the dominant voice in national politics and the beneficiaries of the government’s economic policies, while earlier efforts designed to ameliorate the suffering of the majority were suspended or even reversed, leaving urban workers and the rural poor to wonder what had happened to their revolution. Gradually, a consumerist culture eclipsed the cultural revolution of the 1920s and 1930s. Despite official claims to the contrary, Mexico in this era shed its revolutionary identity and replaced it with a modernizing zeal.
Through the 1960s, scholarly assessments regarded the nation as a model of Third World development. In the estimation of foreign and domestic observers alike, the combination of aggressive capitalist development, state protectionism, and foreign investment had created an economic miracle, while the 1910 Revolution had produced a relatively benign, paternalistic form of “soft” authoritarianism. But in the years following the devastating massacre of students in 1968 at the Plaza de Tlatelolco just days before the Mexico City Summer Olympics, scholarly assessments soured. In the coming decades, more and more evidence of political violence, media manipulation, and official corruption would surface, leading to a crisis of political legitimacy that would be severely aggravated by economic crisis in 1982. For these reasons, the period from 1946 to 1982 is a distinct and important chapter in the nation’s 20th-century development.
