“The gap between kings has its own Latin word — because Romans planned for the chaos of power vacuums five centuries before Christ.”
Latin interrēgnum means 'between reigns,' from inter (between) + rēgnum (kingdom, reign, from rēx, king). In the Roman Kingdom, when a king died, the Senate appointed an interrex — a senator who held power for five days before passing it to the next interrex. This chain continued until a new king was chosen. The system assumed that the gap between rulers was a period of danger requiring temporary management.
The most famous interregnum in English history lasted from 1649 to 1660, the period between the execution of Charles I and the restoration of Charles II. During this gap, England was governed as a Commonwealth and then a Protectorate under Oliver Cromwell. The word interregnum was applied to this period almost immediately — the Latin term was already familiar to the classically educated political class.
The Great Interregnum of the Holy Roman Empire (1254-1273) was longer and messier. After the death of Emperor Conrad IV, no universally recognized emperor ruled for nineteen years. Regional princes governed their own territories, and the empire existed in name only. The period demonstrated what the Roman Senate had feared: an interregnum left unmanaged becomes anarchy.
Modern English uses interregnum for any gap in leadership or authority — the interregnum between CEOs, between governments, between eras. The word implies that the gap is temporary and that a new authority will eventually fill it. It is a word that carries the confidence of continuity: the system will produce a successor. The only question is when.

The interregnum is the moment when the script runs out. The old authority is gone and the new one has not arrived. In that gap, everything that was held in place by the old order begins to drift. Some things improve. Others collapse. Most just wait.
Power, it turns out, is like oxygen — you do not notice it until it is absent. The interregnum names the absence. It is the silence between songs, the breath between sentences, the space where what comes next is still unknown.
