Nemo was indeed originally written as a former Polish rebel against Russian rule, but Verne's publisher objected on the grounds that this might offend Russians[1], and so the published version of Twenty Thousand Leagues had no mention of national origin or ethnicity for Nemo. [1] Both because the Russian market was important for sales of French books -- and government censorship in Russia was a strong possibility -- and because the publisher supported France's ongoing negotiations with Russia for a potential alliance, and worried a book promoting anti-Russian themes might make the negotiations more difficult.
