A Three-Layer Analysis (TLA) of Livy, History of Rome, Book 1
1. Research Question
Why can the end of monarchy be read not as failure, but as the result of an OS that was effective in one phase becoming unfit for the next phase?
Livy’s History of Rome, Book 1 describes the rise, development, and end of the Roman monarchy. If we look only at the end of the monarchy, it is easy to read it as a story in which the tyranny of Tarquinius Superbus destroyed the monarchy and led Rome to the republic.
However, from the viewpoint of Three-Layer Analysis (TLA), the Roman monarchy was not a failed system from the beginning. Rather, it functioned effectively in the founding phase, the integration and expansion phase, and the institutional maturation phase.
This study reads the end of the monarchy not as the total failure of the monarchy OS, but as the result of a centralized OS that was effective up to one phase becoming unfit for the next phase, where distribution, correction, oversight, and institutional operation became necessary.
2. Abstract
This research case analyzes the rise, development, and end of the Roman monarchy in Livy’s History of Rome, Book 1 through Three-Layer Analysis (TLA) and OS Organizational Design Theory (OSODT).
Layer 1 identifies the major sequence of events: the founding of Rome by Romulus, the development of religious institutions by Numa, external integration under Tullus and Ancus, urban and civic development under Tarquinius Priscus and Servius Tullius, and finally the rule by fear and collapse of the monarchy under Tarquinius Superbus.
Layer 2 extracts the structural order behind these events. The monarchy was not merely personal domination. In the founding phase, it functioned as a high-output OS. In the integration and expansion phase, it functioned as an engine for absorbing external groups. In the age of Servius Tullius, it prepared Rome for institutional maturation.
Layer 3 derives the main insight. The end of the monarchy was not the result of monarchy being invalid from the beginning. It was the result of an OS that was effective in the founding phase becoming unfit for the mature phase, where correction, oversight, Trust, and stable institutional operation were required.
The end of the monarchy was not merely a failure. It was a process in which the Roman OS moved from a centralized founding structure to a political OS that could operate on a larger scale through sharing, correction, and oversight.
3. Research Method
This study uses Three-Layer Analysis (TLA).
Layer 1 organizes the events of Rome’s monarchy in Livy’s History of Rome, Book 1 as facts. The main subjects are the founding by Romulus, the institutionalization of religion by Numa, the integration of Alba by Tullus, the expansion under Ancus and Tarquinius Priscus, the institutional reforms of Servius Tullius, and the rule by fear and end of the monarchy under Tarquinius Superbus.
Layer 2 reads these events as structural order. The main elements are royal power, the Senate, the assembly, civic approval, the army, religious institutions, the urban community, civic integration, the institutional maturation phase, and the final transition phase of the monarchy.
Layer 3 uses OS Organizational Design Theory (OSODT) to abstract the phase fitness of the monarchy OS. The analysis refers to founding infrastructure, maintenance infrastructure, phase mismatch, Decision-Criteria Validity (V), Information Flow Architecture (IA), Human Resource Governance (H), Trust (T), correction, oversight, and redistribution of Control Variables.
Through this method, the end of the monarchy is understood not as the simple failure of an institution, but as an OS update caused by phase mismatch.
4. Layer 1: Fact
In Livy’s History of Rome, Book 1, the Roman monarchy is not negative from the beginning.
Romulus founded Rome. He organized law, created the Senate, increased the population, and integrated surrounding communities. At the beginning, Rome lacked population, marriage networks, military organization, walls, religious order, the Senate, law, and civic integration. In this phase, concentrated royal power worked as a driving force for forming the community in a short time.
Numa gave religious institutions, Trust, and peace to a Rome that had been formed through war. He established fear of the gods, priesthoods, the calendar, pontifical order, and rites of good faith. He stabilized a rough community through a religious OS.
Tullus Hostilius expanded Rome through war and integration. In the conflict with Alba, war, single combat, treaty, betrayal, punishment, and population transfer were used to integrate an external community into Rome.
Under Ancus and Tarquinius Priscus, Rome continued to expand in military, urban, diplomatic, religious, and demographic terms.
In the age of Servius Tullius, the monarchy moved further toward institutionalization. The census, property classes, centuries, assemblies, military obligations, and urban divisions were developed. Rome began to move from personal rule by one king toward a system that could reproduce order through records, classification, burden, voting order, and mobilization.
However, under Tarquinius Superbus, the nature of royal power changed.
Tarquinius did not become king through stable approval. He seized power through an attack on Servius Tullius, usurpation, and crimes within the royal family. He also refused burial to Servius, killed or exiled leading nobles, and maintained royal power through armed guards.
Roman citizens became dissatisfied with Tarquinius because of killings, exile, and confiscation of property. Tarquinius also tried to implant in the Latin peoples the same fear that he used to suppress Roman citizens.
Then the Lucretia incident occurred. The crime committed by Sextus Tarquinius, a member of the royal family, was not understood only as a private crime. It was recognized as a danger of the monarchy OS itself. Brutus swore not only revenge against the royal family, but also that no one would ever again be allowed to rule as king in Rome.
Finally, Tarquinius was refused entry into Rome and declared an exile. Brutus was received by the army as a liberator. The monarchy ended. After that, two consuls were elected, and Rome moved toward republican operation.
5. Layer 2: Order
From the viewpoint of Layer 2, monarchy was not merely personal domination.
Royal power was the governing core that carried founding, war, institution-building, and judgment. In the founding phase, Rome was still an unfinished community. It had few people, weak marriage networks, insufficient institutions, and unstable legitimacy.
In this phase, strong decision-making by the king was more effective than dispersed deliberation. A powerful initiator such as Romulus had to move many Control Variables at once: population acquisition, law, the Senate, the army, religious order, and integration of surrounding communities.
Therefore, the monarchy OS in the founding phase was rational as a high-output OS.
The monarchy OS was also effective in the integration and expansion phase. Rome did not expand only through war. It transformed the outside into the inside through peace agreements, colonies, civic integration, marriage, and mixed military organization. To conquer, absorb, and reorganize surrounding communities, royal power, military organization, declaration rituals, alliances, colonies, and civic integration had to operate together.
Thus, early Roman monarchy was not merely a system of domination. It was an integration engine.
However, as the state expanded and became more institutionalized, the conditions required of the monarchy OS changed.
In the age of Servius Tullius, the personal capacity of the king began to be replaced by reproducible institutions such as the census, property classes, centuries, and assemblies. As the state became larger, it became necessary to make visible who should bear what burden, who should speak in what order, and how citizens should be mobilized.
In this sense, the Servian reform was both the completion of monarchy and preparation for a system beyond monarchy.
This is because, as institutionalization progresses, rule depends less on the charisma or violence of one king and more on records, procedures, approval, and role allocation.
In the mature phase, the role of the king is no longer to break through problems by personal strength alone. The king must support long-term stability while aligning with institutions, the Senate, the assembly, military organization, and civic approval.
Royal power that cannot adapt to this change is no longer the driving force of the founding phase. It becomes a risk that destroys mature institutions.
This phase mismatch occurred under Tarquinius Superbus.
His problem was not simply that he was a strong king. The problem was that, in a maturing Rome, he used royal power not for institutional operation of the community, but for self-preservation, rule by fear, removal of opponents, and confiscation of property.
In the founding phase, concentration of authority produces speed.
In the mature phase, concentration of authority produces loss of correction.
If this turning point is missed, monarchy changes from an OS that creates the community into an OS that destroys the community.
6. Layer 3: Insight
The end of the monarchy does not mean that monarchy itself was a failed system from the beginning.
Rather, the Roman monarchy was effective up to a certain phase. In the founding phase, it was a high-output OS for launching the community. In the integration and expansion phase, it was an integration engine that brought external groups into Rome through conquest, alliance, civic integration, and colonies. In the institutional maturation phase, the reforms of Servius Tullius moved royal power toward institutional replacement of personal capacity.
However, once Rome reached a certain scale and developed military organization, civic classification, property order, assemblies, the Senate, and religious institutions, the monarchy OS began to face phase mismatch. Too many Control Variables remained concentrated in one king.
In OSODT, a high-output and high-load structure that is effective in the founding phase can exhaust an organization if it continues into the maintenance phase. In the maintenance phase, what is needed is low-cost, reliable institutional operation, correction, oversight, and continuity.
The same structure applies to the Roman monarchy.
In the founding phase, monopoly produces speed.
In the mature phase, monopoly produces loss of correction.
When the king serves the purpose of the community, concentrated authority can become integration power. But when the king prioritizes self-preservation, concentrated authority becomes destructive power.
Under Tarquinius, royal power was used not for community preservation, but for the self-preservation of the royal family. Institutions such as the Senate, the assembly, the army, treaties, and command authority still existed. But they did not fully function as correction, oversight, and approval.
In this condition, the monarchy OS was no longer a high-output OS of the founding phase. It had become a privatized OS that preserved itself through fear.
Therefore, the end of the monarchy should not be read as the simple disposal of the monarchy OS. It should be read as the redistribution of Control Variables.
When the monarchy ended, Rome did not abandon command authority, military organization, approval, religion, law, or civic organization. Rather, it redistributed these elements from the monopoly of one king to multiple offices, the Senate, the assembly, the army, and institutions.
Regime change does not mean stopping governance.
It means moving the Control Variables required for governance into a structure that fits the next phase.
In this sense, the end of the monarchy can be read as the evolution of the Roman OS.
Rome moved from the founding OS of monarchy to a republican OS based on sharing, correction, and oversight. Sharing enables multi-sided judgment. Correction fixes errors. Oversight restrains the abuse of power.
Therefore, the end of the monarchy was not simply a catastrophe. It was a structural change that allowed Rome to move toward a larger and more durable political OS.
7. Implications for the Present
This structure also applies to modern companies, public organizations, schools, and local communities.
In the founding phase of an organization, a strong leader can be effective. Fast decision-making, resource acquisition, customer development, breakthrough under incomplete rules, and crisis response may require centralized decision-making.
However, when an organization grows and departments, rules, personnel systems, evaluation systems, information channels, customer bases, and legal requirements become more complex, continuing to use the same centralized OS becomes dangerous.
Top-down control that was once effective can later create silence on the frontline.
Fast judgment can become arbitrary judgment.
Leadership that once created integration can become uncorrectable concentration of power.
High-load operation that once created breakthrough can later create exhaustion and distrust.
The important point is not to deny a structure that was effective in the past. The problem is whether that structure still fits the current phase.
When an organization enters the mature phase, what is needed is not only a strong individual. The organization needs alignment with institutions, public approval, information flow, correction, oversight, fair Human Resource Governance, and maintenance of Trust.
In other words, the organization must move from a founding OS to a maintenance OS.
If this transition fails, the organization collapses through its past success pattern. Leadership that once produced success becomes the cause of failure in the next phase. Monopoly of judgment that was once effective creates information blocking and loss of correction in the mature phase.
In modern organizations, the key question is not whether the system worked in the past.
The key questions are as follows.
Does this system fit the current phase?
Are Control Variables too concentrated in one person?
Is there a role that can correct errors?
Does oversight function?
Does information move from the frontline to the upper layer?
Are decision criteria aligned with the purpose of the organization?
Is Human Resource Governance operated fairly?
Are institutions trusted?
When these conditions are lost, an organization can be destroyed by the OS that once made it successful.
8. Conclusion
The end of the monarchy in Livy’s History of Rome, Book 1 does not mean that monarchy was a failure from the beginning.
Rather, monarchy was effective in the founding phase of Rome. Romulus launched the community. Numa institutionalized the religious OS. Tullus and Ancus integrated external groups. Tarquinius Priscus and Servius Tullius developed the city, military organization, and civic institutions.
Monarchy was the OS that created Rome.
However, as Rome grew and became more institutionalized, the conditions required of the monarchy OS changed. Centralized power that was effective in the founding phase began to create the risk of loss of correction and privatization in the mature phase.
Under Tarquinius Superbus, royal power was used not for community preservation, but for the self-preservation of the royal family and rule by fear. At this point, the monarchy OS changed from a state-forming engine into a state-destroying factor.
Therefore, the end of monarchy was not merely a failure.
It was the result of an OS that was effective up to one phase becoming unfit for the next phase.
Rome did not abandon command authority or institutions. It redistributed the Control Variables that had been concentrated in one king to multiple offices, the Senate, the assembly, the army, and institutions.
The end of monarchy was not the disposal of an OS.
It was the redistribution of Control Variables.
It was the transition from a founding OS to a next-stage political OS with sharing, correction, and oversight.
In this sense, the end of the Roman monarchy can be read not as the failure of the Roman OS, but as the evolution of the Roman OS.
