In the 20th century, the role of the wife in Western marriage changed in two major ways; the first was the breakthrough from an "institution to companionate marriage"; for the first time since the Middle Ages, wives became distinct legal entities, and were allowed their own property and allowed to sue. Until then, partners were a single legal entity, but only a husband was allowed to exercise this right, called coverture. The second change was the drastic alteration of middle and upper-class family life, when in the 1960s these wives began to work outside their home, and with the social acceptance of divorces the single-parent family, and stepfamily or "blended family" as a more "individualized marriage".
