A widow is a woman whose husband has died, while a widower is a man whose wife has died. The state of having lost one's spouse to death is termed widowhood. These terms are not applied to a divorc(é)e following the death of an ex-spouse.
The term widowhood can be used for either sex, at least according to some dictionaries, but the word widowerhood is also listed in some dictionaries. Occasionally, the word viduity is used. The adjective form for either sex is widowed.
The treatment of widows around the world varies, but unequal benefits and treatment generally received by widows compared to those received by widowers globally has spurred an interest in the issue by human rights activists.
When the death of a spouse occurs, it is said that a widowhood effect is to arise. This is a phenomenon that refers to the increased mortality rate after the death of a spouse. It is “strongest during the first three months after a spouse's death, when they had a 66-percent increased chance of dying”. Most widows and widowers suffer from this effect during the first 3 months of their spouse's death, however they can also suffer from this effect later on in their life for much longer than 3 months. There remains controversy over whether women or men have worse effects from becoming widowed, and studies have attempted to make their case for which side is worse off, while other studies try to show that there are no true differences based on gender and other factors are responsible for any differences.
In societies where the husband is the sole provider, his death can leave his family destitute. The tendency for women generally to outlive men can compound this, since men in many societies marry women younger than themselves. In some patriarchal societies, widows may maintain economic independence. A woman would carry on her spouse's business and be accorded certain rights, such as entering guilds. More recently, widows of political figures have been among the first women elected to high office in many countries, such as Corazón Aquino or Isabel Martínez de Perón.
