1865

The year 1865 occupies a pivotal position in the intellectual and technological landscape of Jules Verne's "Twenty Thousand Leagues Under the Sea," functioning as a reference point for scientific publications, the Nautilus's construction, and broader historical currents that inform the narrative's themes of exploration, vengeance, and progress.

Scientific and Literary Milestones

1865 was a landmark year for the scientific and literary works that directly influenced the novel. Verne himself published "From the Earth to the Moon" that year, a work of speculative fiction about space travel that, like the present novel, anticipated future technologies. More directly, the book "The Founders of Astronomy" by Joseph Bertrand, which appeared in 1865, provided Professor Aronnax with a crucial clue about the Nautilus's age. Finding this volume in Captain Nemo's library, Aronnax concluded that the fitting out of the Nautilus could not have taken place before 1865, meaning the captain had begun his underwater existence at most three years prior to the events of 1868. This dating establishes the Nautilus as a marvel of very recent, secret construction, underscoring its status as a vessel ahead of its time.

The Nautilus's Construction and Technological Context

The year 1865 also marks the upper boundary for the Nautilus's assembly. Captain Nemo reveals that he built his submersible using components sourced from different countries—its keel forged by Creusot in France, its propeller shaft by Pen & Co. in London, its sheet-iron plates by Laird's in Liverpool, and its engine by Krupp in Prussia. The precision instruments came from Hart Bros. in New York. This global industrial collaboration, culminating in 1865 or shortly thereafter, highlights the advanced state of 19th-century engineering that Verne imaginatively synthesized. The Nautilus's electric rifle, which fires glass capsules charged with high-voltage electricity, is another technological marvel that, while fictional, reflects the era's fascination with electricity as a motive and destructive force. The novel's own subtitle, "An Underwater Tour of the World," and its episodic structure echo the travelogue style popularized by Verne's earlier works, including the 1865 "From the Earth to the Moon."

Historical and Political Undercurrents

The year 1865 is also significant for the political and historical events that resonate through the novel's subtext. The American Civil War had just ended, and the assassination of Abraham Lincoln, a figure whose portrait hangs in Captain Nemo's stateroom, occurred in that year. Nemo's collection of portraits—including Lincoln, John Brown, and other champions of oppressed peoples—suggests his alignment with the cause of liberation and his hatred of tyranny. Furthermore, the novel's original conception was influenced by the 1863 Polish uprising against Tsarist Russia, an event that, though occurring two years earlier, shaped Verne's initial vision of Nemo as a Polish nobleman seeking vengeance. The political pressures of the 1860s forced Verne to revise this backstory, but the spirit of rebellion against imperial oppression remains a core theme. The year 1865 thus encapsulates the era's scientific optimism, industrial ambition, and unresolved political conflicts that provide the moral and emotional depth to Captain Nemo's quest.
