Aninterregnum (pluralinterregna orinterregnums) is a period ofdiscontinuity or "gap" in a government, organization, orsocial order. Archetypally, it was the period of time between the reign of one monarch and the next (coming from Latininter-, "between" andrēgnum, "reign" [fromrex, rēgis, "king"]), and the concepts of interregnum andregency therefore overlap. Historically, longer and heavier interregna have been typically accompanied by widespread unrest,civil andsuccession wars betweenwarlords, andpower vacuums filled by foreign invasions or the emergence of a new power.[1]
The term also refers to the periods between the election of a new parliament and the establishment of a new government from that parliament in parliamentary democracies, usually ones that employ some form of proportional representation that allows small parties to elect significant numbers, requiring time for negotiations to form a government. In the UK, Canada and other electoral systems withsingle-member districts, this period is usually very brief, except in the rare occurrence of ahung parliament as occurred bothin the UK in 2017 andin Australia in 2010. In parliamentary interregnums, the previous government usually stands as acaretaker government until the new government is established. Additionally, the term has been applied to theUnited States presidential transition, the period of time between the election of a newU.S. president and their inauguration, during which the outgoing president remains in power, but as alame duck.[1]

In some monarchies, such as the United Kingdom, aninterregnum is usually avoided due to a rule described as "The King is dead. Long live the King", i.e. theheir to the throne becomes a new monarch immediately on his predecessor's death orabdication. This famous phrase signifies the continuity ofsovereignty, attached to a personal form of power namedAuctoritas. This is not so in other monarchies where the new monarch's reign begins only withcoronation or some other formal or traditional event. In thePolish–Lithuanian Commonwealth for instance, kings were elected, which often led to relatively long interregna. During that time it was the Polishprimate who served as aninterrex (ruler between kings). InBelgium the heir only becomes king upon swearing anoath of office before theparliament.
