Thu is a nation on Urras defined in the novel by state control of information, strategic rivalry, and a history of expansion beyond its home world. Its presence in the story links political censorship and warfare to the founding of Anarres: a secret Thuvian settlement on the Moon became part of the crisis that prompted the Council of World Governments to offer the Moon to the Odonians. Centuries later, Thu’s war with A-Io is fought in Benbili, while the conflict brings censorship and travel restrictions into force on Urras.

Government, Information, and Public Knowledge

Thu’s government controls the press more directly than A-Io does. When Shevek examines newspapers, Pae identifies one paper as Thuvian and describes it as well printed and sober in format. He contrasts it with A-Io’s press: although A-Io permits a proliferation of newspapers, its educated readers chiefly turn to telefax, radio, television, and weekly reviews. In Thu, by contrast, censorship is absolute, and news reports only the facts the Thuvian Central Presidium wants published. The contrast presents two different arrangements of information: the abundance and social stratification of A-Io’s press against the state’s deliberate restriction of what can be known in Thu.

The image of Thu that reaches Anarres also comes through an organized history lesson. A class on the Odonian Movement shows a famine in Bachifoil Province, where children’s bodies are burned on beaches, alongside scenes of women in A-Io kept for the sexual use of propertied men and served by people from the unpropertied class. The commentary explicitly places the scenes side by side. Thu thus enters the lesson not as an abstract rival but as a place where famine and state failure have consequences for ordinary lives; the juxtaposition also connects suffering across different political systems rather than treating it as unique to one nation.

A Secret Lunar Settlement and the Founding of Anarres

Thu’s history on the Moon predates the Odonian settlement. While the Moon was formally under the jurisdiction of the Council of World Governments, Thu secretly maintained a rocket base and a gold-mining settlement in the eastern hemisphere, where miners lived with their wives and children. The other governments did not know the settlement existed; the Thuvian government alone knew of it. This covert presence complicates the appearance of an otherwise uninhabited world and shows that lunar extraction had already involved more than the publicly acknowledged mining operation at Anarres Town.

The collapse of Thu’s government in 771 exposed the consequences of that hidden settlement. The Council proposed giving the Moon to the International Society of Odonians, in part to buy them off before their movement undermined law and national sovereignty on Urras. Anarres Town was evacuated, and two hurried final rockets were sent from Thu to collect the gold miners. Not all chose to return to Urras; some stayed because they preferred the desert. Their presence and departure form part of the chain of events through which a contested mining frontier became the home of the Odonians.

War in Benbili and Restrictions on Urras

Much later, Thu is at war with A-Io over Benbili. A newspaper headline reports a clash near the Benbili capital, and Pae says that A-Io has taken the capital and intends to reinstall General Havevert. When Shevek asks whether the war is over, Pae explains that it is not: Thu still holds two eastern provinces, so A-Io and Thu will continue fighting in Benbili. The account locates the fighting outside the rival powers’ own territories, even as their armies confront each other there.

Pae presents this arrangement as a way to avoid war at home: neither nation would be so foolish as to invade the other, and the balance of power is maintained through what he calls a police action. But A-Io is officially at war, and the declaration activates restrictions. Research at the College of Noble Science is subject to classification; publication can be delayed when officials judge a paper dangerous; and non-nationals, including Shevek, are not supposed to leave campus without clearance from the Chancellor. Pae says he can evade the travel rules for Shevek, but his confidence underscores that the rules are real even when officials or insiders find ways around them.

Political Attitudes and the Limits of the State’s Account

The war’s public justification is framed in terms of national standing. When Shevek asks Atro whether people in A-Io approve of the conflict, Atro answers that the country cannot let the Thuvanians walk over it and insists that A-Io’s status as a world power is at stake. Shevek clarifies that he is asking about the people who must fight, not the government. The exchange exposes the difference between a state’s account of its strategic interest and the question of consent among those who bear the consequences.

The information environment makes that distinction harder to pursue. Shevek notices that newspapers which once used excited, argumentative language now echo the wording of government telefax bulletins. Their failure to offer moral judgment on the war is part of what prompts his question to Atro. The text does not establish what the population of Thu thinks about the war, but its earlier account of absolute censorship makes the limits on independent knowledge there especially stark when set against A-Io’s wartime control of research, publication, and movement.

Narrative Significance

Thu connects the book’s account of social order across several scales: a hidden settlement on the Moon, the political decision that makes Anarres available to the Odonians, and a later war that allows A-Io to narrow ordinary freedoms in the name of security. The nation is not developed through a single sustained viewpoint; it is encountered through a classroom image, the description of a newspaper, historical exposition, and reports about the war. That indirect presentation makes Thu both a concrete political power and a test of what Urrasti characters can know about states beyond their own.

Its contrast with A-Io is pointed rather than simple. Thu’s absolute censorship is explicit, but A-Io’s formally freer press does not prevent government language from overtaking public reporting during war. Likewise, the claim that the conflict can be kept away from the rival powers’ own territory coexists with restrictions on Shevek’s research and travel. Through this contrast, Thu helps illuminate a wider pattern: political borders and declarations do not contain the effects of power, which reach into information, mobility, and the lives of people elsewhere.
