modernization, in sociology, the transformation from a traditional, rural, agrarian society to a secular, urban, industrial society.

Modern society is industrial society. To modernize a society is, first of all, to industrialize it. Historically, the rise of modern society has been inextricably linked with the emergence of industrial society. All the features that are associated with modernity can be shown to be related to the set of changes that, some 250 years ago, brought into being the industrial type of society. This suggests that the terms industrialism and industrial society imply far more than the economic and technological components that make up their core. Industrialism is a way of life that encompasses profound economic, social, political, and cultural changes. It is by undergoing the comprehensive transformation of industrialization that societies become modern.

Modernization is a continuous and open-ended process. Historically, the span of time over which it has occurred must be measured in centuries, although there are examples of accelerated modernization. In either case, modernization is not a once-and-for-all-time achievement. There seems to be a dynamic principle built into the very fabric of modern societies that does not allow them to settle, or to achieve equilibrium. Their development is always irregular and uneven. Whatever the level of development, there are always “backward” regions and “peripheral” groups. This is a persistent source of strain and conflict in modern societies. Such a condition is not confined to the internal development of individual states. It can be seen on a global scale, as modernization extends outward from its original Western base to take in the whole world. The existence of unevenly and unequally developed nations introduces a fundamental element of instability into the world system of states.

Modernization seems to have two main phases. Up to a certain point in its course, it carries the institutions and values of society along with it, in what is generally regarded as a progressive, upward movement. Initial resistance to modernization may be sharp and prolonged, but it is generally doomed to failure. Beyond some point, however, modernization begins to breed discontent on an increasing scale. This is due in part to rising expectations provoked by the early successes and dynamism of modern society. Groups tend to make escalating demands on the community, and these demands become increasingly difficult to meet. More seriously, modernization on an intensified level and on a world scale brings new social and material strains that may threaten the very growth and expansion on which modern society is founded. In this second phase, modern societies find themselves faced with an array of new problems whose solutions often seem beyond the competence of the traditional nation-state. At the same time, the world remains dominated by a system of just such sovereign nation-states of unequal strengths and conflicting interests.

Yet challenge and response are the essence of modern society. In considering its nature and development, what stands out initially at least is not so much the difficulties and dangers as the extraordinary success with which modern society has mastered the most profound and far-reaching revolution in human history.

This article discusses the processes of modernization and industrialization from a very general and primarily sociological point of view. It does so also, it should be remembered, from a position within the very processes it describes. The phenomena of industrialization and modernization that are taken to have begun more than two centuries ago and that were not until much later identified as distinct and novel concepts have not yet arrived at any recognizable closure. The end of the story, if there is one, is thus not in sight, and the question of an ultimate judgment on the nature and value of this vast historical movement is unanswerable.
