Interrēges

（μεσοβασιλεῖς). The name given by the Romans to the senators who, between the death of one king and the election of another, held regal authority, during the interregnum, for successive periods of five days each. One of these interreges had to conduct the election itself. Even under the Republic an interrex was nominated by the Senate to hold the Comitia for the election of consuls, whenever the consuls had died, or resigned, or if the election had not been completed by the end of the year. If five days did not suffice, the retiring interrex named another to succeed him. See Mommsen, Röm. Staatsrecht, vol. i. 647-660.
