The Maurai series is a series of short stories and a novel by Poul Anderson set in a resource depleted, post-apocalyptic earth several centuries in the future. The series is named after its most frequent protagonists, citizens of the Maurai Federation. The Maurai (originally descended from Māori peoples of N'Zealann and other Polynesians, but including a diverse array of ethnic and racial groups) dominate the Pacific and Indian Oceans. Fearful of the social and ecological implications of a return to large-scale industrial society, they use their considerable might and covert resources to prevent other nations from developing nuclear power.
InOrion Shall Rise, the novel that culminated the series, Anderson allowed for the possibility that a more equitable distribution of power, and an advanced, space-faring civilization, might evolve.
