Hello! Welcome back to our exploration of Sparta.
In our last lesson, we delved into the very heart of Spartan society. We saw how the constant fear of the Helots shaped a rigid three-tiered social structure and how the brutal agoge was designed to forge the world's most disciplined soldiers. We now understand how Sparta created its warriors; today, we'll investigate who led them.
Our objective for this lesson is to explain the structure of Spartan government, including the dual monarchy and the Gerousia. While other Greek cities experimented with tyranny, oligarchy, and early forms of democracy, Sparta developed something unique: a "mixed constitution" that blended elements of all three. It was a complex system of checks and balances that provided the stability needed to run a city that was, in essence, a permanent military camp.
1. The Dual Monarchy: A King for War, A King for Home
The most peculiar feature of Sparta's government, and the one that most baffled other Greeks, was its dual monarchy. Sparta always had two kings, ruling simultaneously, from two separate royal families: the Agiads and the Eurypontids.
This strange arrangement was rooted in mythology and provided immense practical benefits for a state constantly at war. Let's begin by exploring its origins and function.
Sparta's Dual Kingship: How Two Royal Houses Ruled ...
The article 'Sparta’s Dual Kingship' from Spoken Past provides an excellent narrative on the origins and mechanics of this system. It explains the founding myth and the distinct roles the kings played.
Please read the first two main sections of the article: 'Origins of Sparta’s Dual Kingship: The Twin Myth' and 'How Sparta’s Dual Kingship Actually Worked'. Focus on why having two royal lines was so important for their legitimacy and how their powers were divided.
As you've just read, the dual kingship was not a partnership of equals sharing a single crown, but two parallel monarchies. To reinforce this, let's watch a short video that brings the concept to life.
The Constitution of the Spartans
The video 'The Constitution of the Spartans' by Historia Civilis opens by explaining this very concept, based on the account of the ancient writer Xenophon.
Please watch from the beginning to 02:12, and then from 06:24 to 08:55. The first part covers the mythical founding, and the second details the specific powers and duties of the kings.
The key powers of the kings were:
- Military Command: The kings were the supreme commanders of the Spartan army. On campaign, a king's authority was absolute; he held the power of life and death over every soldier. A later reform mandated that only one king lead an army at a time, which had the dual benefit of preventing command disputes and ensuring a king always remained in Sparta to guard against a Helot uprising.
- Religious Authority: They served as chief priests, conducting the public sacrifices essential for securing divine favor before any major state action, especially war.
- Judicial Functions: They had authority in specific cases, notably those concerning adoptions and the marriages of heiresses, which gave them influence over the transfer of property.
However, as powerful as a king was in the field, his authority was significantly limited back home by other governmental bodies.
2. The Gerousia: The Council of Elders
The primary check on royal power, and the main oligarchic element in Sparta's constitution, was the Gerousia, or council of elders. This was arguably the most influential body in the Spartan state.
The Constitution of the Spartans
Let's return to the Historia Civilis video, which gives a concise and clear explanation of the Gerousia's composition and immense power.
Please watch the segment from 16:58 to 19:45. Pay close attention to the Gerousia's ability to control the legislative process.
To summarize and expand on the video:
- Composition: The Gerousia consisted of 30 members: the two kings, plus 28 men elected from the citizenry.
- Requirements: To be elected to the Gerousia, a man had to be over the age of 60—having completed his military service—and held in high regard. The position was held for life.
- Powers: The Gerousia's power was immense and primarily preventative.
- It served as the supreme criminal court, trying cases of homicide and, most importantly, putting kings themselves on trial.
- It prepared all business and proposals to be put before the citizen assembly.
- Crucially, it held veto power over the assembly. Even if the citizens voted to pass a law, the Gerousia could simply set it aside.
This made the Gerousia an incredibly conservative force. Since its members were elderly, aristocratic, and served for life, they ensured that Sparta rarely deviated from its traditions. Change could only happen with their approval.
3. The Ephors: The Annually Elected Overseers
If the kings represented the monarchical element and the Gerousia the oligarchic one, the office of the Ephors represented a democratic and accountability-focused element. The five Ephors were arguably the most powerful officials in Sparta on a day-to-day basis.
The Constitution of the Spartans
The same video from Historia Civilis has an excellent, detailed section on the Ephors, who they were, and the incredible scope of their authority.
Please watch from 08:55 to 16:58. This is a longer segment, but it's crucial for understanding the system of checks and balances. Focus on the relationship between the Ephors and the kings.
The Ephors were unique:
- Composition: Five men elected annually from the entire body of citizens over the age of 30. A man could only serve as an Ephor once in his lifetime.
- Powers: Their name means "overseers," and their job was to check the power of everyone else, especially the kings.
- Each month, the Ephors and kings exchanged oaths: the kings swore to rule by the laws, and the Ephors swore to "keep the kingship unshaken" as long as they did.
- They had the power to bring charges against a king and convene the Gerousia for a trial.
- Two Ephors accompanied a king on every military campaign to monitor his conduct.
- They presided over the Gerousia and the citizen assembly.
- They controlled most aspects of foreign policy, receiving ambassadors and dispatching envoys.
- They oversaw the agoge and held the power of the Krypteia, the secret police used to terrorize the Helots.
The annual election and one-year term limit ensured that this immense power did not become concentrated in the hands of a few. Furthermore, at the end of their term, Ephors were subject to a review by their successors, making them accountable for their actions.
Test your understanding!
A Spartan king, returning from a victorious but controversial campaign, is accused of accepting a bribe from the enemy. Who would have the authority to bring this charge against him, and which body would conduct the trial?
Show answer
The Ephors would have the authority to bring the charge against the king. The trial itself would be conducted by the Gerousia, with the Ephors acting as prosecutors and also sitting as part of the jury.
4. The Complete System: A Machine of State
Finally, all these bodies were connected to the Apella (or Ekklesia), the general assembly of all male Spartan citizens over the age of 30. Its role was limited but essential: it elected the members of the Gerousia and the Ephors, and it voted on laws proposed by them. However, it could not debate or amend proposals; citizens simply shouted "yes" or "no."
Let's look at a diagram to see how all these pieces fit together.

This structure, with its interlocking parts and overlapping powers, created a system of remarkable stability. The kings provided military leadership, the Gerousia provided conservative stability, and the Ephors provided popular oversight and accountability. As the final segment of our video explains, this system of checks and balances was the key.
The Constitution of the Spartans
To conclude, let's watch the final summary from 'The Constitution of the Spartans,' which describes how these institutions worked together in practice, particularly during a trial.
Please watch from 19:45 to the end at 21:51. This section ties together the roles of the Ephors, Gerousia, and Kings.
Conclusion
The government of Sparta was a unique and complex machine, intentionally designed to be stable, conservative, and resistant to radical change. It was a "mixed constitution" long before philosophers like Aristotle and Polybius analyzed the concept.
Key Takeaways:
- Mixed Constitution: Sparta's government blended monarchy (two Kings), oligarchy (the Gerousia), and a democratic element (the Ephors and the Assembly).
- Dual Monarchy: The two kings, from the Agiad and Eurypontid families, were primarily military and religious leaders. Their power was absolute on campaign but limited at home.
- The Gerousia: This council of 30 elders (28 elected + 2 kings) was the most powerful oligarchic body, controlling legislation and acting as the highest court.
- The Ephors: Five annually elected officials served as "overseers," providing a powerful check on the kings and holding significant executive authority over domestic and foreign policy.
- Checks and Balances: No single branch of government had absolute power. The Ephors checked the Kings, the Gerousia checked the Assembly, and the annual rotation of Ephors prevented any one group from dominating for long.
Preview of the Next Lesson:
Having examined Sparta's rigid, military-focused state, we will now turn our attention to its great rival. In the next lesson, we will begin to explore a completely different path of political development by tracing the development of Athenian democracy from the reforms of Solon to Cleisthenes. You will see how one city built a state around the hoplite soldier, while another began to build one around the citizen.
