As social historian Barbara Dafoe Whitehead has observed of this period, "divorce was not only an individual right but also a psychological resource.
The dissolution of marriage offered the chance to make oneself over from the inside out, to refurbish and express the inner self, and to acquire certain valuable psychological assets and competencies, such as initiative, assertiveness, and a stronger and better self-image." But what about the children?
Most important, the psychological revolution of the late '60s and '70s, which was itself fueled by a post-war prosperity that allowed people to give greater attention to non-material concerns, played a key role in reconfiguring men and women's views of marriage and family life.
Prior to the late 1960s, Americans were more likely to look at marriage and family through the prisms of duty, obligation, and sacrifice.
But the psychological revolution's focus on individual fulfillment and personal growth changed all that.
Increasingly, marriage was seen as a vehicle for a self-oriented ethic of romance, intimacy, and fulfillment.
The new law eliminated the need for couples to fabricate spousal wrongdoing in pursuit of a divorce; indeed, one likely reason for Reagan's decision to sign the bill was that his first wife, Jane Wyman, had unfairly accused him of "mental cruelty" to obtain a divorce in 1948.
But no-fault divorce also gutted marriage of its legal power to bind husband and wife, allowing one spouse to dissolve a marriage for any reason — or for no reason at all.
In the decade and a half that followed, virtually every state in the Union followed California's lead and enacted a no-fault divorce law of its own.
This legal transformation was only one of the more visible signs of the divorce revolution then sweeping the United States: From 1960 to 1980, the divorce rate more than doubled — from 9.2 divorces per 1,000 married women to 22.6 divorces per 1,000 married women.
