The patricentric and nuclear family traditionally served as the norm and the ideal in Portugal. Until the constitution of 1976 was published, the father was seen as the head of the family, and his wife and children were obliged to recognize his authority. He, in turn, was obliged by law to support and protect his family. While the men worked outside the home, women were expected to care for the children and manage household affairs. Marriage was considered permanent; divorce was virtually unknown. During the time of Salazar’s rule from 1928 to 1968, the family was even seen as the primary institution of politics; voting was organized under the regime, the Estado Novo -New State, on a family basis–only “heads of households” could vote.

Still, some characteristics of Portuguese family life remained constant. Marriage and kinship networks in Portugal were often based on social and political criteria as much as on love or natural attraction. To a degree that often surprised outsiders, even in the early 1990s many Portuguese marriages were arranged. For the peasant class, considerations of land were often most valuable in determining marriage candidates. Marriages might be arranged to consolidate property holdings or to tie two families together rather than result from the affection two people might feel for one another. Middle-class families often had status and prestige considerations in mind when they married. Among the upper classes, marriage might be for the purposes of joining two businesses, two landholdings, or two political clans.
