Ireland, ca. early twentieth century. Certainty of
paternity has been considered important in a wide range of eras and cultures, especially when inheritance and citizenship were at stake, making the tracking of a man's estate and genealogy a central part of what defined a "legitimate" birth. The ancient
Latin dictum, "
Mater semper certa est" ("The [identity of the] mother is always certain", while the father is not), emphasized the dilemma. In Italy during the Renaissance, a sharp distinction was made between two kinds of illegitimate children: a natural child, both of whose parents were unmarried, and a spurious child, at least one of whose parents was married, but not to the other parent. Natural children were commonly recognized as heirs, with little shame attached, while spurious children were generally looked down upon. The higher the status of the family, the less the stigma mattered. For example,
Cesare Borgia, a spurious child of Rodrigo Borgia (later
Pope Alexander VI), was legitimized by a papal decree. His father the Pope made him a Cardinal at the age of 18. In English
common law, Justice
Edward Coke in 1626 promulgated the "Four Seas Rule" (
extra quatuor maria) asserting that, absent impossibility of the father being fertile, there was a
presumption of paternity that a married woman's child was her husband's child. That presumption could be questioned, though courts generally sided with the presumption, thus expanding the range of the presumption to a "Seven Seas Rule". But it was only with the
Marriage Act 1753 that a formal and public marriage ceremony at civil law was required, whereas previously marriage had a
safe haven if celebrated in an
Anglican church. Still, many "clandestine" marriages occurred. In many societies, people born out of wedlock did not have the same rights of
inheritance as those within it, and in some societies, even the same
civil rights. In the United Kingdom and the United States, as late as the 1960s and in certain social strata even up to today, nonmarital birth has carried a
social stigma. In previous centuries unwed mothers were socially pressured to give their children up for
adoption. In other cases nonmarital children have been reared by
grandparents or married
relatives as the "sisters", "brothers" or "cousins" of the unwed mothers. In most national
jurisdictions, the status of a child as a legitimate or illegitimate heir could be changed—in either direction—under the
civil law: A legislative act could deprive a child of legitimacy; conversely, a marriage between the previously unmarried parents, usually within a specified time, such as a year, could retroactively
legitimate a child's birth. Fathers of illegitimate children often did not incur comparable
censure or legal responsibility, due to
social attitudes about
sex, the nature of sexual reproduction, and the difficulty of determining
paternity with
certainty. By the final third of the 20th century, in the
United States, all the states had adopted uniform laws that codified the responsibility of both parents to provide support and care for a child, regardless of the
parents'
marital status, and gave non-marital as well as
adopted persons equal rights to inherit their parents' property. In the early 1970s, a series of
Supreme Court decisions abolished most, if not all, of the common-law disabilities of non-marital birth, as being violations of the
equal-protection clause of the
Fourteenth Amendment to the United States Constitution. Generally speaking, in the United States, "illegitimate" has been supplanted by the phrase "born out of wedlock." In contrast, other jurisdictions (particularly western continental European countries) tend to favour social parentage over the biological parentage. Here a man (not necessarily the biological father) may voluntarily
recognise the child to be identified as the father, thus giving legitimacy to the child; the biological father does not have any special rights in this area. In
France, a mother may refuse to recognize her own child (see
anonymous birth). A contribution to the decline of the concept of illegitimacy had been made by increased ease of obtaining
divorce. Before this, the mother and father of many children had been unable to marry each other because one or the other was already legally bound, by civil or
canon law, in a non-viable earlier
marriage that did not permit divorce. Their only recourse, often, had been to wait for the death of the earlier spouse(s). Thus Polish political and military leader
Józef Piłsudski (1867–1935) was unable to marry his second wife,
Aleksandra, until his first wife,
Maria, died in 1921; by this time, Piłsudski and Aleksandra had two out-of-wedlock daughters. ==Social implications==
