Around 4056 BBY, Taris descended into civil war. Toxic pollution poisoned the planet's oceans and famine spread through the city-world. Upper-class nobles hoarded food while the largely alien lower classes suffered. The lower city rose in rebellion, but the aristocratic regime crushed the uprising after millions of deaths.

When scarcity becomes a city's class war
What the record establishes
Taris's toxic seas and food scarcity brought elite resource control into direct conflict with the lives of people below the wealthy districts. Aristocratic hoarding is central to the Legends account, not an incidental detail. Poor Humans and non-Humans participated in the rebellion, so describing the struggle only as one species opposing another would erase the economic divisions running through both populations.
The institutional and social consequences
The defeat of the rebellion created new conditions for punishment, including the expansion of exclusion to the Undercity. Urban height and legal status came to reinforce one another. The later stories about Taris reveal the legacy of this hierarchy, but the episode should not be confused with the planet's much later military destruction. Exact casualty figures are reported retrospectively rather than through contemporary rolls.
Did the rebellion establish equal access to Taris's food and political institutions?
No. The ruling elite defeated the revolt and deepened systems of exclusion.

Environmental collapse becomes social conflict
Pollution damaged food systems and intensified scarcity.
Ecological crisis did not affect all groups equally because elites controlled access to resources.
Class and species overlap
Taris's nobility was heavily Human while much of the lower class was alien.
Economic hierarchy therefore reinforced species hierarchy.
The Undercity becomes a penal landscape
Upper-level prisons overflowed during the crisis.
Authorities increasingly cast criminals and unwanted citizens into the Undercity under threat of death if they returned.
Anthropological assessment
The Tarisian Civil War shows how environmental crisis can become political violence when scarcity is distributed through unequal institutions.
The postwar segregation of space physically embedded class and species hierarchy into the architecture of the city.
Early Republic / source-led investigation
Scarcity becomes an urban class war
The Tarisian Civil War arose amid polluted oceans, failing food supplies and increasingly unequal access to resources. The wealthy inhabitants of Taris's higher districts were able to protect themselves through control of supplies and administrative power. The less privileged people in the lower levels, many of them non-Human, endured conditions that became politically intolerable. The rebellion and the regime's military response led to enormous suffering. The surviving account connects ecological disruption to the way a layered city distributes risk.
The defeat of the lower-city uprising did not restore an equal civic order. The repression helped entrench the practices that would later mark Taris: harsh control over movement, deep species and class divisions, and the casting of unwanted people into the Undercity. By the time Revan and Carth visited Taris in 3956 BBY, the architecture of inequality was already part of ordinary life. The Sith blockade operated over that earlier social history rather than inventing it. Keeping the events separate shows how older conflicts can shape the experience of a new occupation.
Ecology becomes political through institutions
Famine may begin with environmental disruption, but the way food is distributed determines who suffers first and who can endure scarcity. Control of wealth, security and physical access magnified inequalities on Taris.
Violence persists in urban geography
The separation of Upper City, Lower City and Undercity provided a durable framework for exclusion. Later citizens inherited physical barriers that expressed the outcome of past political struggles.
Did the Sith create the Undercity class divide when they occupied Taris in 3956 BBY?
No. The social hierarchy and punitive uses of the Undercity had developed long before that occupation.

c. 4056 BBY · Legends · Primary source context
Taris: ecology, class and punitive exile
Documented sequence
Legends material connects Taris's civil war to declining trade importance, toxic industrial pollution, widespread food insecurity and the unequal distribution of resources in the city-world. The nobility's response to lower-class rebellion included military suppression and exile to the Undercity. The conflict is dated approximately to 4056 BBY.
Political and cultural implications
The source does more than describe two armed factions. It connects environmental degradation to inequality: those controlling protected supplies survived while lower-level populations faced hunger and violent policing. The Undercity's exile policy extended the effects of the war across generations and turned architectural layers of the city into administrative boundaries.
What the evidence cannot show
Dialogue about famine and social injustice comes from Legends characters in a particular later political setting. The records are valuable, but figures about casualties or the precise timing of policy changes need their original source context. Taris's later rakghoul outbreaks must not be backdated as the original cause of the civil war.
Source judgment: Was the Tarisian Civil War caused only by an isolated military dispute?
Explanation: No. Later accounts also describe pollution, food scarcity, class inequality and the loss of key trade routes.
Legends · Political and material consequences
Scarcity and the geography of exclusion
The Tarisian Civil War was bound to environmental collapse and unequal access to necessities. Pollution, food shortages and elite hoarding shaped who could survive and who could influence the city-world's decisions. The uprising involved economic hierarchy as well as differences between Human and non-Human populations. Reducing the account to a single-species conflict would erase impoverished Humans and the significance of class.
Upper-city privilege and lower-city deprivation became spatial expressions of power. Political institutions could regulate access to resources and then criminalize the populations most harmed by scarcity. The aftermath contributed to an increasingly punitive geography, including exclusion from safer urban spaces. These structural observations should not become invented first-person testimonies or precise demographic counts. The later Knights of the Old Republic story offers a view of the divided city, not eyewitness footage from every stage of the earlier civil war.
Evaluate the evidence: Was the uprising merely a conflict between all Humans and all non-Humans?
Correction: No. The historical account connects environmental scarcity and class, with poverty crossing species categories.
