 During the mid-20th century, under French influence and among upper classes, women started to take up their husbands' surname(s).From the 1960s onwards, this usage spread to the common people, again under French influence, this time, however, due to the forceful legal adoption of their husbands' surname which was imposed onto Portuguese immigrant women in France.From the 1974 Carnation Revolution onwards the adoption of their husbands' surname(s) receded again, and today both the adoption and non-adoption occur, with non-adoption being chosen in the majority of cases in recent years (60%).
