In the early 7th century BCE, Sparta formed a gerousia of 30—28 elders plus the two kings—to prepare measures for the people’s vote. Life tenure promised continuity; Aristotle later called it a danger. In the open air, thirty voices guided thousands.
What Happened
The Great Rhetra’s most concrete number is thirty. It fixed the gerousia—the council of elders—at 28 members, plus the two kings, the ARCHAGETAI, to make 30 [5]. In a valley where bronze shields flashed and the Eurotas ran cold, this small circle would shape the laws a crowd would later approve by shout. The logic was Spartan: mix monarchy and oligarchy, then let the people attest. Tyrtaeus gives us the order in verse: the “God‑honoured Kings” begin counsel, the elders weigh, and then the people answer with “forthright ordinances” [8]. This probouleusis kept proposals narrow and speech short. The gerousia curated agenda. Elders held life tenure. Aristotle, writing in the 4th century, winced. Old men can err, he argued; power that lasts a lifetime tempts bribery. He also mocked the method of selecting gerontes by acclamation as “childish,” though he acknowledged the council’s authority in practice [6]. That critique itself testifies to the gerousia’s durability: the council survived long enough to irk philosophers. Geography again shaped politics. Without halls, the gerousia deliberated in Spartan spaces—the Agora near the acropolis, sanctuaries at Therapne, later the Skias—then brought measures to the plain “between Babyca and Cnacion” [5][7]. The soundscape mattered. A herald’s cry, the rising roar of approval, the sudden hush when a motion faltered. Numbers inside numbers stabilized the whole. Two kings bound by twenty‑eight elders; a five‑man ephorate to rise as overseers; phylai and obai beneath. In bright Laconian sun, the gerousia’s proposals met a crowd trained at mess and in rank to move together [2][5][21]. Where the shout twisted, kings and elders later claimed power to adjourn—an amendment as old as Polydorus and Theopompus. But at the center of Sparta’s mixed constitution, the gerousia held the pen that wrote the first draft of law [5].
Why This Matters
The gerousia converted charismatic kingship into a predictable sequence: counsel begins at the top, flows through elders, then meets the people’s shout [5][8]. Thirty men could steer decisions for thousands, providing continuity during Messenian pressures. This event illustrates Probouleusis and Acclamation in action. The elders’ life tenure and agenda control made popular consent stable—but also vulnerable to the stagnation and corruption Aristotle attacked [6]. The same features that secured order could calcify it. Across the wider story, the gerousia’s authority legitimized later checks—like adjourning a crooked vote—because those checks came from the same apex. The council’s endurance, visible from Herodotus to Aristotle, makes it the spine of the Lycurgan order [2][6].

People Involved
Key figures who played a role in Gerousia of 30 Established
Theopompus
Theopompus, a Eurypontid king of seventh‑century Sparta, ruled during the formative decades after Lycurgus. Tradition credits him—alongside the Agiad Polydorus—with the ‘rider’ that empowered kings and the gerousia to dissolve an assembly that veered into unlawful decisions. He is also the figure to whom some ancient sources ascribe the establishment of the ephorate, later a powerful check on kings. His reign wove battlefield leadership with constitutional restraint, embodying the Spartan maxim that a smaller kingship made more lasting by law is stronger than a larger one secure only in fear.
Polydorus
Polydorus, an Agiad king of Sparta in the seventh century BCE, ruled during the turbulent era of the Messenian Wars and the consolidation of Lycurgan institutions. Tradition pairs him with his Eurypontid counterpart Theopompus as the author of a crucial ‘rider’ to the Great Rhetra: when the assembly “spoke crookedly,” the kings and the gerousia could dissolve the meeting. In a city that prized discipline as salvation from civil strife, Polydorus helped anchor kingship within a lawful, mixed constitution. His reign bridged battlefield demands with constitutional prudence, ensuring that Spartan power rested as much on controlled deliberation as on spear and shield.
Lycurgus
Lycurgus is the semi-legendary lawgiver whom Greek tradition credits with founding Sparta’s distinctive constitution and way of life. Drawing on Cretan models and sanctified by an oracle at Delphi, he issued the Great Rhetra, which fused dual kingship, a 30-member council of elders, and a popular assembly meeting under the open sky. He is said to have instituted the syssitia—common messes—and drilled citizens to live as comrades-in-arms. Whether one man or a composite, Lycurgus stands at the heart of the reforms that turned Spartan fear of disorder into a disciplined order admired by Xenophon and questioned by Aristotle. His constitution made law sacred and collective life paramount—Sparta’s enduring signature.
