Twenty Thousand Leagues Under the Seas is a famous adventure novel. 
The story begins when ships see a mysterious sea monster in 1866. A group travels from New York City to find it. Professor Pierre Aronnax is a French scientist who joins the mission. He travels on a ship called the Abraham Lincoln. Along with him are Ned Land, a Canadian harpooner, and Conseil, a faithful servant. During a fight with the monster, the men fall into the ocean. They soon find that the monster is actually a submarine. This vessel is the Nautilus, which is commanded by the mysterious Captain Nemo. 
Captain Nemo built the Nautilus in total secrecy. He uses electricity to power the ship. This was a very advanced idea for the 1860s. In those days, most submarines were quite primitive. Verne was inspired by a model of a French submarine called the Plongeur. He saw this model at the Musée de la Marine in 1867. The Nautilus allows Nemo to roam the seas away from governments. He uses the ship to study marine life and conduct research. The title refers to the 20,000 leagues the ship travels, not its depth.

Captain Nemo is a complex man with a sad history. He lives in exile to escape the world of men. He often helps people who are being treated unfairly. For example, he helps a pearl-hunter from an oppressed land. Some scholars believe Nemo's character was based on a Polish nobleman. However, his publisher, Pierre-Jules Hetzel, asked to change these details. He wanted to avoid political trouble in France and Russia. Later, Verne wrote about Nemo again in The Mysterious Island. In that book, Nemo is revealed to be an Indian prince named Dakkar.
Twenty Thousand Leagues Under the Seas is a classic science fiction adventure novel. 
The plot begins in 1866 when ships report sightings of a mysterious sea monster. Many people believe the creature is a gigantic narwhal. In response, the United States government organizes an expedition from New York City. Professor Pierre Aronnax, a French marine biologist, joins the mission as a narrator. He travels on the Navy frigate Abraham Lincoln under Admiral Farragut. He is accompanied by Ned Land, a skilled Canadian harpooner, and Conseil, Aronnax's devoted Flemish servant. During an attack on the creature near Japan, the men are thrown into the sea. They discover the monster is actually a futuristic submarine called the Nautilus.
The Nautilus is commanded by the mysterious Captain Nemo. Nemo is the designer of the vessel and lives in self-imposed exile. He built the submarine in secrecy to roam the oceans beyond the reach of governments. The ship is electrically powered, which was a very advanced concept in the 1860s. At that time, most existing submarines were quite primitive. Verne likely drew inspiration from a model of the French submarine Plongeur. He saw this model at the Musée de la Marine in 1867. 
During their journey, the passengers experience many diverse environments. They travel through the Pacific and Atlantic Oceans. 

Captain Nemo is a complex character with a tragic background. The novel suggests he went into exile after his homeland was conquered. His family was reportedly killed by a powerful imperialist nation. This loss drives his desire to stay away from human society. However, Nemo still shows compassion for the oppressed. He provides money to rebels in the Cretan Revolt of 1866–1869. He also helps an Indian pearl-hunter by giving him a pouch of pearls. Nemo identifies himself as a member of the oppressed, just like the diver. 
Historians have noted interesting details about how the book was edited. In early drafts, Nemo was a Polish nobleman. His family had been killed during the Polish January Uprising of 1863. Verne's publisher, Pierre-Jules Hetzel, requested that these details be removed. He wanted to avoid political tension between France and the Russian Empire. This change ensured the book would not face trouble in Russian translations. Later, Verne revisited the character in The Mysterious Island. In that later book, Nemo is revealed to be an Indian prince named Dakkar. He was a descendant of Tipu Sultan and fought in the Indian Rebellion of 1857.
The novel connects to many real-world scientific and historical ideas. Verne references the famous oceanographer Matthew Fontaine Maury. Maury was known for charting the world's oceans and studying currents. The story also alludes to famous French explorers like Lapérouse and d'Urville. The Nautilus even passes through a fictional underwater passage under the Suez Canal. Some critics believe the book anticipates the modern ecology movement. Others see the battle with the giant squid as a symbol of the Industrial Revolution. This depth of meaning makes the novel a significant work of literature.
