A Confederate veteran is inexplicably transported to Mars, where his Earth-honed strength makes him a chieftain among green-skinned giants and the only hope for a captive red princess.
John Carter, a Virginian gentleman and former Confederate captain, recounts his mysterious journey to Mars. After prospecting for gold in Arizona and escaping Apache pursuit, he seeks refuge in a cave. Overcome by a strange paralysis, he finds himself staring at the red planet. When he recovers, he discovers his physical body is still in the cave, but his consciousness has been transported to Mars. He immediately notices the planet's lower gravity, which gives him superhuman strength and leaping ability, though he initially struggles with coordination. He observes the desolate landscape and the two moons of Barsoom.
Soon after arriving, John Carter encounters a horde of green-skinned, four-armed, six-limbed Martian giants known as Tharks. Despite their initial hostility, his unusual appearance and incredible strength, a result of Earth's higher gravity conditioning, impress them. He is captured and taken to their fortress. Among the Tharks, he meets Sola, a relatively compassionate female Thark who is assigned to care for him. Through observation and Sola's subtle guidance, Carter begins to learn the Thark language and their brutal, warlike customs, which prioritize strength and indifference to emotion.
During a raid, the Tharks capture a group of red Martians, including the beautiful Princess Dejah Thoris of Helium. John Carter is immediately captivated by her beauty and grace, a stark contrast to the harsh Thark environment. He feels a powerful urge to protect her. Dejah Thoris is defiant and proud, refusing to submit to her captors. Carter, using his superior strength, intervenes to save her from a cruel Thark warrior, showing his chivalry and earning respect from both Dejah Thoris and the Tharks, especially Sola and the chieftain Tars Tarkas.
John Carter's fighting skills and strategic thinking quickly raise his status among the Tharks. He engages in a duel with Ma Haud, a formidable Thark warrior, and defeats him, further solidifying his reputation. He forms an unlikely friendship with Tars Tarkas, a powerful Thark chieftain, who is intrigued by Carter's honor and courage, qualities rare among his own people. Carter also learns of Tars Tarkas's secret sorrow: the loss of his mate, Go-lia, and their daughter, Sola, showing the suppressed emotions within Thark society.
The Tharks, along with their captives including John Carter and Dejah Thoris, travel to the city of Warhoon to meet with a rival green Martian tribe. During a skirmish, Carter and Dejah Thoris seize an opportunity to escape. They flee into the Martian wilderness, pursued by both Tharks and Warhoons. Their journey is dangerous, forcing them to rely on each other for survival against the harsh Martian environment, dangerous creatures, and constant threat of recapture. This shared ordeal deepens their bond and mutual respect.
While escaping, John Carter and Dejah Thoris fall into a hidden pit, a trapping device for Martian creatures. They are separated, with Carter falling deeper into the complex underground system. Dejah Thoris is recaptured by the Warhoons, while Carter encounters a terrifying, ape-like creature which he defeats. He eventually finds his way out, only to learn of Dejah Thoris's renewed captivity. His determination to rescue her intensifies, driving him to confront new dangers and seek out her whereabouts.
John Carter, after much searching, reunites with Tars Tarkas. He learns that Sarkoja, a cruel Thark, has usurped Tars Tarkas's position and is responsible for many injustices. Carter aids Tars Tarkas in a dramatic challenge, helping him defeat Sarkoja and reclaim his rightful place as Jeddak (chieftain) of the Tharks. During this time, Tars Tarkas reveals to Carter the truth about his mate, Go-lia, and their daughter, Sola, confirming his suppressed emotional capacity and solidifying their bond of friendship and loyalty.
With Tars Tarkas's support, John Carter leads a group of Tharks to the city of Zodanga, where Dejah Thoris is being held captive and forced into a marriage with Sab Than, the Jeddak of Zodanga. Carter's strategic brilliance and the Tharks' ferocity lead to a decisive victory against Zodanga. He frees Dejah Thoris and helps to unite the Heliumite forces with the Tharks, forming a powerful alliance against their common enemies. This act cements his heroic status among both red and green Martians.
Following the defeat of Zodanga and the established alliance, John Carter marries Dejah Thoris in a grand ceremony, solidifying his place within Martian society. He is granted the title of Prince of Helium and becomes a beloved and respected leader. For ten years, Carter and Dejah Thoris live happily, during which time they have a son, Carthoris. Carter dedicates himself to the prosperity and defense of Helium, proving himself a capable statesman and warrior, deeply devoted to his new family and planet.
After ten years, a catastrophic crisis befalls Barsoom: the planet's atmosphere, artificially sustained by a vast atmosphere-generating plant, begins to fail. The plant's operators, the Thern, have mysteriously disappeared, and the machinery is grinding to a halt, threatening all life on Mars with suffocation. The air becomes thin and cold, causing widespread panic and despair among the Martian populace. John Carter recognizes the urgency of the situation and knows that only immediate action can prevent total annihilation.
John Carter, understanding the dire consequences of the failing atmosphere, volunteers for the dangerous mission to reach the atmosphere plant, located in a remote and heavily guarded region. He knows the journey is fraught with peril, not only from the hostile environment but also from the mysterious Thern, who are believed to guard the plant. His mission is to bypass the security, understand the plant's workings, and restart it before Barsoom becomes uninhabitable, a race against time for the survival of the entire planet.
John Carter successfully infiltrates the atmosphere plant, encountering numerous traps and challenges. He discovers the mechanisms and, using his ingenuity, manages to restart the plant, saving Barsoom from certain death. However, as he attempts to leave the plant, a strange force or mechanism within the plant itself, perhaps designed to protect its secrets, inexplicably transports him back to Earth, leaving him once again in the Arizona cave where his journey began, his heart aching for Dejah Thoris and his adopted planet.

The novel explores the contrast of primitive, warlike societies (Tharks) with more advanced, cultured ones (red Martians). John Carter, a 'civilized' man from Earth, finds common ground and even nobility within the 'savage' Tharks, especially Tars Tarkas and Sola, who have hidden depths of emotion and honor. Conversely, the 'civilized' red Martians are shown to be capable of war and intrigue, challenging simple ideas of civilization. This theme is clear when Carter, despite his initial revulsion, forms a deep bond with Tars Tarkas, recognizing his good qualities.
“And in the eyes of my Thark friend I read a message which, though unintelligible, was yet as strong as though it had been spoken.”
A central theme is the powerful bond of love and loyalty that crosses species and cultural divides. John Carter's devotion to Dejah Thoris drives much of the plot, inspiring him to brave countless dangers. Similarly, his friendship with Tars Tarkas, forged through mutual respect and shared experience, shows how loyalty can bridge the gap between different societies. Sola's loyalty to Carter, despite the Thark rule against emotion, further highlights this theme. These relationships show the universal nature of these feelings.
“I knew that in all the universe there was no other for me than Dejah Thoris, and I would have sacrificed a thousand lives for her.”
John Carter's journey is a display of human adaptability. Transported to an alien world with different gravity, atmosphere, and customs, he quickly learns to navigate its challenges. His Earth-born strength becomes an advantage, but his true survival depends on his intelligence, quick thinking, and willingness to learn the language and social structures of Barsoom. This theme is constantly present as Carter learns to jump, fight, and even lead in a world entirely foreign to him, showing the resilience of the human spirit in extreme circumstances.
“I was an absolute stranger in a strange land, but I was a fighter; I was a Virginian.”
John Carter embodies the ideals of chivalry and honor, which are often lacking in the brutal Martian societies. His actions, such as protecting Dejah Thoris from harm, fighting fair, and keeping his word, consistently set him apart. These qualities earn him respect and admiration from both the red Martians and even some Tharks, ultimately enabling him to form alliances and achieve his goals. His honor guides him through the moral complexities of Barsoom.
“I was not of their race, but I was a man, and a man's honor is his life.”
John Carter's mysterious transfer of consciousness to Mars.
This device immediately establishes the fantastical premise of the story. John Carter's physical body remains on Earth, while his consciousness (or 'astral form') is transported to Mars. This allows him to experience Mars directly without the logistical challenges of space travel in the early 20th century. It also sets up his eventual, equally mysterious return, leaving an open-ended question about the nature of his journey and creating a sense of wonder and cosmic mystery.
Earth's gravity grants Carter superhuman abilities on Mars.
This is a key plot device that provides John Carter with an immediate advantage on Barsoom. Due to Earth's higher gravitational pull, his muscles are overdeveloped compared to Martians, granting him superhuman strength and the ability to leap great distances. This allows him to survive initial encounters, impress the Tharks, and perform heroic feats that would otherwise be impossible, instantly establishing him as a formidable force in the Martian landscape and a unique individual.
A critical, vulnerable technology sustaining all life on Barsoom.
The atmosphere plant serves as a crucial MacGuffin and a ticking clock device in the later stages of the novel. It highlights the technological advancement and fragility of Martian civilization, as all life depends on this single, vulnerable mechanism. Its failure creates a planet-wide existential threat, providing a powerful motivation for John Carter's final heroic mission and raising the stakes to their absolute highest, impacting every inhabitant of Barsoom.
Carter's initial inability to communicate and subsequent mastery of Martian languages.
The language barrier is initially a source of conflict and misunderstanding, emphasizing Carter's alien status. His gradual acquisition of the Thark and then the red Martian languages, primarily through observation and the help of Sola, is a vital plot device. It allows him to integrate into Martian society, understand their customs, forge alliances, and participate in complex political and military strategies, moving him from an outsider to an integral part of Barsoom.
