The Great Rebellion is the revolt through which the Outer Worlds won independence from Earth, the “mother planet.” In the evidence available here, it is not staged as a battle but survives as a political and cultural dividing line: Earth’s formal education largely stops short of the Outer Worlds’ later history, and the inherited separation shapes what Earth people know—and misunderstand—about Spacer society.

Independence and historical distance

Earth’s formal education gives virtually no information about Outer World history or sociology after the Great Rebellion. The omission leaves a consequential gap: the worlds’ independence is part of the background of Earth life, but the social history that followed it is not part of ordinary schooling. That distance helps explain why Earth stereotypes can stand in for knowledge.

Popular bookfilm romances fill the gap with stock figures: the visiting tycoon, the beautiful heiress who falls for an Earthman, and the arrogant Spacer rival who is ultimately beaten. These fantasies deny basic realities of contact: Spacers do not enter Cities, and Spacer women virtually never visit Earth. The Rebellion thus marks more than a constitutional separation; its aftermath has produced worlds so socially apart that Earth’s popular stories imagine encounters that rarely occur.

Population and political consequences

The separation also persists in arguments over whether Earth and the Outer Worlds can share political and social arrangements. R. Daneel Olivaw explains that the Outer Worlds’ Nationalist parties have grown stronger as efforts on Earth continue to fail. They argue that Earthmen differ from Spacers and cannot be fitted into the same traditions, and warn that imposing robots on Earth by superior force could bring destruction to the Galaxy.

The population comparison gives those arguments their weight: Earth has eight billion people, while all fifty Outer Worlds together have scarcely more than five and a half billion. R. Daneel connects this divide to the concerns of Roj Nemennuh Sarton and his colleagues on Earth. In the passages provided, the Great Rebellion is therefore visible less through its military course than through the enduring conflict over independence, difference, and the consequences of trying to impose a common order.
