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 are only two ruling Regencies in the world, sovereign Liechtenstein and Thailand. The following is a list of regents.

It should be noted that 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.
