Thebes is presented as an example of a formerly free city whose political habits made it difficult for an outside power to hold securely. In the comparison between Spartan and Roman methods of conquest, its fate demonstrates that replacing self-government with an externally supported oligarchy may control a city for a time without extinguishing the civic memory that can eventually turn against the conqueror.

Political Status and Historical Setting

Thebes belongs to the category of cities and provinces that had previously lived under their own laws and in freedom. The text treats such communities as fundamentally different from territories accustomed to hereditary princely rule. A city shaped by obedience to a prince may be left without its ruling line and then attached comparatively easily to a new master; a free city, by contrast, retains political habits, collective memory, and the language of liberty through which resistance can later be organized.

Thebes is therefore not introduced through a detailed local biography, but through a general history of conquest and government. Its significance lies in what it represents: a city whose established civic order cannot be treated as a superficial custom that disappears merely because a foreign ruler has occupied it. The old political identity remains a potential source of renewed resistance whenever the conqueror suffers weakness or misfortune.

Spartan Rule and the Oligarchic Method

The Spartans held Thebes, along with Athens, by creating oligarchies in those cities. This method attempted to govern a free community indirectly, placing authority in the hands of a limited group of inhabitants who could serve the conquering power. Such a regime could function as an instrument of control because its position depended upon the protection of the new ruler and it therefore had an immediate interest in defending that ruler against the wider population.

The arrangement nevertheless proved temporary. The text states that the Spartans eventually lost both Athens and Thebes, making the cities examples of a policy that could impose administration without securing lasting possession. The failure does not arise from a lack of formal government; it arises from the unresolved tension between an imposed oligarchy and the remembered freedom of the city it governs. A dependent local regime may command for a period, but it does not necessarily neutralize the political identity of the people beneath it.

Memory of Freedom and the Problem of Retention

Thebes helps clarify the book's severe claim that a city accustomed to freedom cannot safely be preserved without either destruction or direct residence by the conquering prince. Free institutions give the inhabitants a language under which rebellion can be sheltered: they can present resistance not simply as disobedience, but as the recovery of ancient laws and liberty. No length of time and no accumulation of benefits is guaranteed to erase that memory.

This logic makes the city politically durable even when its visible institutions have been altered. An oligarchy may replace the former order, yet the older civic tradition remains available as a rallying point. The example of Pisa's rising against the Florentines after a century of servitude reinforces the same principle, while Thebes supplies the earlier historical instance of a free city that the Spartans could occupy but not permanently secure.

Comparative Significance

Thebes is set against Roman practice. The Romans destroyed Capua, Carthage, and Numantia and consequently did not lose them; when they attempted to hold Greece while leaving it free and governed by its own laws, they failed and had to destroy many cities before their authority became secure. The contrast makes Thebes part of a larger comparative argument about the relation between political form and imperial durability.

Its role is also connected to the distinction between kingdoms ruled through a single prince and kingdoms structured around powerful hereditary nobles. In a centralized state, once the ruling family and armies have been defeated, few independent figures remain who can mobilize the population. A city such as Thebes presents the opposite problem at the civic level: its political vitality is not exhausted by the removal of one ruler, because freedom has been remembered as a collective inheritance. Thebes thus stands as a compact historical warning that conquest of territory is not the same as possession of a political community.
