Monarchic Republic

A monarchic republic, as historian Anthony Kaldellis uses the term, is a state governed by a single ruler with real executive power who nonetheless operates inside a polity still understood, in the Roman sense, as a res publica — a commonwealth or common concern to be served, not a possession to be inherited or owned. Kaldellis applies the term to the Eastern Roman Empire (conventionally ‘Byzantium’) across its entire thousand-year run from Constantine to 1453, and treats it as the concept that resolves an apparent puzzle in the empire’s constitution: how a state with an all-powerful emperor at its head could also behave, structurally, like a republic.

The mechanism: legitimacy without inheritance

No emperor held a hereditary right to the throne. Roman res publica — the term the state used of itself throughout, even under emperors — never meant a non-monarchical regime the way the word ‘republic’ does in modern usage; for Romans it meant the common affairs of a political community, compatible in principle with rule by a king, a senate, or an assembly. An emperor’s job was to serve that common concern, and the sources consistently frame the office that way, whatever the ruler’s actual personal conduct. Because there was no dynastic claim to fall back on, each emperor had to re-earn legitimacy continuously rather than inherit it once.

The mechanism for that continuous test was not periodic election but mass acclamation. Wherever large numbers of Romans gathered — the Hippodrome in Constantinople above all, but also army musterings, church congregations, and public fora — the crowd’s cheering or its silence and jeering told an emperor, in real time, whether his rule still held public consent. Kaldellis calls this a perpetual referendum: unlike a modern election, which delivers a fixed mandate for a fixed term, the East Roman monarchy was subject to an ongoing opinion poll with no term limit and no guaranteed renewal. In one recorded instance from the 1190s, Emperor Alexius III announced a new tax to a hostile Hippodrome crowd and reversed the policy within the same public appearance.

The ultimate enforcement mechanism, when persuasion failed, was civil war. Roughly 120 civil wars occurred across the thousand years Kaldellis studies, and 46% of Constantinopolitan emperors were deposed by violence — a strikingly high figure that functions, in his account, as the real constitutional check on the monarchy, standing in for the institutional constraints a modern state would use instead.

Why this differs from a dynastic empire

Kaldellis draws the contrast explicitly with dynastic empires such as the Ottoman state, where a single ruling family created the polity through conquest and sat at its permanent centre. The Roman emperor, by contrast, emerged from within an existing republic and never fully escaped that origin: even the earliest emperors (Augustus onward) had to maintain the fiction of being merely the republic’s first citizen, holding offices the Senate had granted rather than a crown outright. That the facade had to be maintained at all, for centuries after any real prospect of Senate rule had disappeared, is itself evidence for Kaldellis that the republican substrate was not empty theatre.

One structural consequence follows directly: because there was no dynastic claim to lean on, emperors were incentivised to keep the population’s tolerance high through visible good government, rather than through the kind of domestic military repression seen in many other authoritarian states across history — the army in this system was almost never turned against the empire’s own civilian population.

Where mainstream views differ

Popular accounts of the Roman and Byzantine imperial system, and much of the traditional historiography, default to describing the office as an autocracy or, especially for the military emperors of the third century onward, a military dictatorship — a reading Kaldellis directly rejects on the grounds that the army was structurally not used as an instrument of domestic social control. Other historians place more weight on Roman monarchy’s genuinely absolute legal powers (an emperor’s word was law, with no formal veto), treating the ‘republic’ language as inherited rhetorical convention rather than a living constitutional constraint. Kaldellis’s position is that the rhetoric and the constraint were not so easily separated: an emperor who ignored the republican bargain too openly did not survive it.
