Abdication is the act of formally relinquishing monarchical authority. Abdications have played various roles in the succession procedures of monarchies. While some cultures have viewed abdication as an extreme abandonment of duty, in other societies (such as pre-Meiji Restoration Japan), abdication was a regular event and helped maintain stability during political succession.
Historically, abdications have occurred both by force (where the regnant was forced to abdicate on pain of death or other severe consequences) and voluntarily. Some rulers are deemed to have abdicated in absentia, vacating the physical throne and thus their position of power, although these judgements were generally pronounced by successors with vested interests in seeing the throne abdicated, and often without or despite the direct input of the abdicating monarch.
Recently, due to the largely ceremonial nature of the regnant in many constitutional monarchies, many monarchs have abdicated due to old age, such as the monarchs of Spain, Cambodia, the Netherlands and Japan.
The word abdication is derived from the Latin abdicatio meaning to disown or renounce (ab, away from, and dicare, to proclaim). In its broadest sense abdication is the act of renouncing and resigning from any formal office, but it is applied especially to the supreme office of state. In Roman law the term was also applied to the disowning of a family member, such as disinheriting a son. Today the term commonly applies to monarchs. An elected or appointed official is said to resign rather than to abdicate. A notable exception is the voluntary relinquishing of the office of Bishop of Rome (and thus sovereign of the Vatican City State) by the pope, called papal resignation or papal renunciation.
In certain cultures, the abdication of a monarch was seen as a profound and shocking abandonment of royal duty. As a result, abdications usually only occurred in the most extreme circumstances of political turmoil or violence. For other cultures, abdication was a much more routine element of succession.
