"The link between colonialism and science-fiction is every bit as old as the link between science-fiction and the future. John Rieder in his eye-opening book Colonialism and the Emergence of Science-Fiction notes that most scholars believe that science fiction coalesced "in the period of the most fervid imperialist expansion in the late nineteenth century." Sci-fi "comes into visibility," he argues, "first in those countries most heavily involved in imperialist projects—France and England" and then gradually gains a foothold in Germany and the U.S. as those countries too move to obtain colonies and gain imperial conquests. He adds, "Most important, no informed reader can doubt that allusions to colonial history and situations are ubiquitous features of early science fiction motifs and plots.""
