10 May – Commonwealth (Adultery) Act (1650) imposes the death penalty for incest, and for adultery, that is defined as sexual intercourse between a married woman and a man other than her husband. Both partners would be liable for death sentence in such a case, although the courts are reluctant to impose the ultimate penalty.[1] If a man (married or unmarried) has sex with an unmarried woman (including a widow), that would be fornication, punishable only by three months for first offenders, applicable to both partners.[1][2] In the history of adultery in English law, this represents the only time since the twelfth century when adultery has been outlawed in secular statute law.[3]
