The religious theory of the family which prevailed during the Middle Ages, but which was more or less undermined by the Reformation, gave away entirely in those great social changes which ushered in the nineteenth century. Again, the view that marriage was a private contract came to prevail among the mass of the people, and even to be embodied in a great many of the constitutions and laws of the nineteenth century. At the same time profound economic changes tended largely to individualize society, and these were reflected in the democratic movement toward forms of popular government, which have tended on the whole to make the individual the political unit. The nineteenth century was, then, in all respects a period of great social change and unrest. Moreover, the growth of wealth has favored, in certain classes at least, lower moral standards and increasing laxity in family relationships. Thus it happens that we find the family life at the beginning of the twentieth century in a more unstable condition than it has been at any time since the beginning of the Christian era. The instability of the modern family is, indeed, so great that many have thought that the family, as an institution, in its present form at least, of permanent monogamy, will pass away. There can be no doubt, at any rate, that the whole problem of the modern family centers in the matter of its instability, that is, in divorce. The study of the divorce movement, then, will throw more light upon the condition of the modern family than the study of anything else. The instability of the modern family has been most evident in the United States. Hence, it is particularly American conditions that will concern us, although undoubtedly the disintegration of the family is not a peculiarly American phenomenon; rather it has characterized more or less all modern civilization, but is especially in evidence in America because American society has exaggerated the industrialism and individualism which are characteristic of Western civilization in general. Without devoting too much time to the consideration of divorce statistics in their technical aspects, let us note, then, some of the main outlines of the modern divorce movement in this and other civilized countries.
