List of regents

A regent is a person selected to act as head of state (ruling or not) because the ruler is a minor, not present, or debilitated.^[1] Currently there is only one ruling Regency in the world, sovereign Liechtenstein. The following is a list of regents.

Regents in extant monarchies

Those who held a regency briefly, for example during surgery, are not necessarily listed, particularly if they performed no official acts; this list is also not complete, presumably not even for all monarchies included. The list includes some figures who acted as regent, even if they did not themselves hold the title of regent.
