While depicting many outlandish inventions, and advanced technology, it is a savage world, of honor, noble sacrifice and constant struggle, where martial prowess is paramount, and where many races fight over dwindling resources.

Origin of the name "Barsoom"

Burroughs frequently made up words from the languages spoken by the peoples in his novels, and used these extensively in the narrative. In Thuvia, Maid of Mars

 he included a glossary of Barsoomian words used in the first four novels. The word "Barsoom", the native Martian word for Mars, is composed of the Martian name for planet, "soom", and the Martian word for eight, "bar". This assumes that Mars is the eighth body in the inner solar system, though to reach this figure it is necessary to count the Sun and the satellites of both the Earth and Mars itself even though they are not planets.

 Burroughs established a practice which continued in four sequels - introducing the novel as though it were a factual account passed on to him personally.

, which was published under the pseudonym, Norman Bean). However, the first novella in John Carter of Mars, "John Carter and the Giant of Mars", is thought to been penned by Burroughs' son John "Jack" Coleman Burroughs, though it is claimed to have been revised by his father. It was recognized as unlikely to be Burroughs' work immediately on publication by fans, as the writing is of a juvenile quality compared to that of Burroughs.

 tales, but include scientific aspects. They mostly take place on the surface of an alien world, frequently include sword fighting, monsters, supernatural elements such as telepathic abilities, and civilizations similar to Earth in pre-technological eras, particularly with the inclusion of dynastic or religious social structures. Spacecraft may appear, but are not central to the story.

The stories also share a number of elements with westerns in that they feature desert landscapes, women taken captive and a final confrontation with the antagonist.

Burroughs' Barsoom stories are considered seminal planetary romances. While examples existed prior to the publication of his works, they are the key influence on the many works of this type that followed. His style of planetary romance has ceased to be written and published in the mainstream, though his books remain in print.

Plot

Like most of Burroughs' fiction, the novels in the series are mostly travelogue

s, feature copious action of a violent nature, and often have plots involving civilized heroes being captured by uncivilized cultures and being forced to adapt to the cruel nature of their captors to survive.

While there is variation, most of the Barsoom novels follow a familiar plot structure. A hero is forced to journey to a far-off location in search of a woman he is either in love with, or believes himself to be. The woman has been kidnapped by an odious but powerful man, who both desires her and values her for his own political ends.
Female characters are frequently threatened with sexual assault; Dejah Thoris (on numerous occasions), Thuvia and Tara of Helium are all subjected to this threat. Tara notably is pursued by a headless body being remotely controlled by telepathy by a Kaldane

.

The hero is awkward with women and will tend to misinterpret their lack of interest in him due to his low confidence or familiarity with the ways of women. Female characters are likely to be virtuous and fight off amorous advances and other dangers until able to connect with the hero. The hero is often forced to adopt a disguise and is not recognized by the heroine.

He will have to fight both strange races and hideous creatures to claim her love. Along the way the hero will encounter kings or other powerful figures who rule over a severely repressed population, ripe for rebellion. He will be instrumental in deposing the ruler, usually with the assistance of a fresh-faced member of the same population, whom the hero will have encountered when both are in some kind of slavery or imprisonment.

Motifs

The world of Barsoom is morally unambiguous; characters are either good or evil, there is no sense of moral relativity. A sense of honor transcends race or political affiliation and characters fight alongside one another, and against their adversaries because it is the right thing to do. Qualities of compassion, loyalty and bravery are celebrated, and callousness, deception, and cowardice are frowned upon.

Typically the novels include descriptions of aspects of the Martian world such as the architecture, and the presence of desolate landscapes punctuated by abandoned cities - whose histories are often elaborated upon, technological achievements, advanced medicine, cultural elements such as superstitious religious practices and eating habits, breeding practices and methods of population control.

Many lost cities and civilizations and journeys into forgotten underworlds appear across the series, and the environment beyond the cities is populated by a variety of ferocious beasts, many roughly equivalent with Earth creatures and most with multiple sets of limbs.

Typically they are rulers or despots of major empires, or little known hidden fiefdoms. They are usually hated by their subjects and possess a voracious sexual appetite, usually directed towards the heroine. The pattern is established by green martian Jeddak, Tal Hajus, in the first novel, A Princess of Mars

Appeal

The popularity of the Barsoom novels may lie in their reflection of the classic 'rags to riches' tale in a fantastic setting, which may resonate with readers who feel undervalued, and whose abilities are unrecognized. The heroes are men of talent and ability whose circumstances have so far failed to give them the opportunity to reach their proper potential. The epic scale adventures of the novels allow their inner selves to manifest, and reward them with love, companionship, freedom and success. These are action heroes who are noble, fearless and never doubt themselves in the face of adversity. They are not skilled in their dealings with women, but are chivalrous and their noble qualities and fearlessness make them attractive to the heroines. The narratives also set a rapid pace, and offer a considerable sense of escapism. They are mostly read by men, but there are female fans as well.

For a time in the late 19th and early 20th centuries, it was erroneously believed that there were canals on Mars.

The Martian year comprises 687 Martian days, a Martian day being 24 hours and 37 minutes (Burroughs probably derived this from Percival Lowell

He referenced winds, snows and marshes which had supposedly been observed by astronomers, as evidence of an atmosphere, and that the wastes of the planet had been irrigated (probably referencing Lowell's canals), which suggested that an advanced civilization existed on the planet.

None return from this pilgrimage, because it leads to almost certain death at the hands of ferocious creatures.

While the Martian females are egg-laying, Martians have mammalian characteristics such as a navel and breasts. While they have skins of various colors, and their bodies differ in some cases from traditional humans, they are very similar to varieties of Earth humans, and there is little examination of how their extraterrestrial biology might make them unusual or particularly distinct from terrestrial humans.

The Red Martians are highly civilized, respect the idea of private property, adhere to a code of honor and have a strong sense of fairness. Their culture is governed by law and is advanced technologically. They are capable of love and have families.

Green Martians

The Green Martians are fifteen feet tall (males) and twelve feet tall (females), have four arms and eyes mounted at the side of their heads. They are nomadic, warlike and barbaric, do not form families, have little concept of friendship or love and enjoy inflicting torture upon their victims. Their social structure is highly communal - they have no concept of private property - and is rigidly hierarchical, consisting of various levels of chiefs, with the highest office occupied by an all powerful Jeddak. However, the title of Jeddak is obtained by mortal combat, rather than hereditary means. They form tribes, which war among one another constantly. They ride aggressive animals, thoats, and armed themselves with swords, lances and firearms which use 'radium' ammunition.

The Green Men are primitive, intellectually unadvanced, do not have any kind of art and are without a written language. While they craft weapons, any advanced technology they possess, such as 'radium pistols', is stolen from raids upon the Red Martians. They inhabit the ancient ruined cities left behind by civilizations which lived on Barsoom during a more advanced and hospitable era in the planet's history. They apparently arose from a biological experimental which went awry and as with all other Martians, they are an egg-laying species, concealing their eggs in incubators until hatching. Tars Tarkas

Thus the followers of Tars Tarkas, based in the ruined ancient city of Thark, are known as "Tharks". Other hordes bear the names of Warhoon, Torquas and Thurd.

 they are found hiding in secret domed cities at the North Pole of Mars. They are bearded, exceptionally cruel and keep slaves, acquiring these by using a giant magnetic device which pulls fliers off course, and allows the Yellow Martians to capture their crews.

Orovars

The White Martians, known as 'Orovars' were rulers of Mars for 500,000 years, with an empire of sophisticated cities with advanced technology. They were white skinned, with blond or Auburn hair. They were once a seafaring race but when the oceans began to dry up, they began to cooperate with the Yellow and Black Martians to breed the Red Martians, foreseeing the need for hardy stock to cope with the emerging harsher environment. They became decadent and 'overcivilized'. At the beginning of the series they are believed to be extinct, but three remaining populations, some original Orovars, Therns and Lotharians, are still living in secret and are discovered as the books progress.

Lotharians

The Lotharians are a remnant population of the original White Martians, which appear only in Thuvia, Maid of Mars

. There are only 1000 of them remaining, all of them male. They are skilled in telepathy, able to project images that can kill, or provide sustenance. They live a reclusive existence in a remote area of Barsoom, debating philosophy among themselves.

Therns

Descendants of the original White Martians who live in a complex of caves and passages in the cliffs above the Valley Dor. This is the destination of the River Iss, on whose currents most Martians eventually travel, on a pilgrimage seeking final paradise, once tired of life or reaching 1000 years of age. The valley is actually populated by monsters, overlooked by the Therns, who control these creatures, and ransack, and eat the flesh of those who perish, enslaving those who survive. They consider themselves a unique creation, different from other Martians. They maintain the false Martian religion through a network of collaborators and spies across the planet. They are themselves raided by the Black Martians. They are white skinned and bald but wear blond wigs.

 and "John Carter and the Giant of Mars". Although the Hormads were generally recognizable as humanoid, the process was far from perfect, and generated monstrosities ranging from the occasional misplaced nose or eyeball to "a great mass of living flesh with an eye somewhere and a single hand."

Technology

When Burroughs wrote the first volume of the Barsoom series, aviation and radio technology was in its infancy and radioactivity was a fledgling science. Despite this, the series includes a range of technological developments including radium munitions, battles between fleets of aircraft, devices similar to faxes and televisions, genetic manipulation, elements of terraforming

The device, built upon existing Martian compass technology, allows the pilot to reach any programmed destination, only having to keep the craft pointed in the set direction. Upon arrival, the device automatically lowers the craft to the surface. He also includes a kind of collision detector, which uses radium rays to detect any obstacle and automatically steer the craft elsewhere, until the obstacle is no longer detected. This works in principle almost identically to the backscatter radiation detector used to fire the braking rockets on the Souyuz space capsule. In Swords of Mars

He also develops a missile which seeks out craft protected in this fashion, and a means of rendering fliers invisible which becomes a key plot device in the novel. However, while advanced weapons are available, most martians seem to prefer melee combat - mostly with swords - and their level of skill is highly impressive.

, he discovers the secret of life, and creates an army of artificial servants and warriors, which are grown in giant vats filled with organic tissue. They frequently emerge deformed, are volatile and are difficult to control, later threatening to take over the planet.

Measurements

Burroughs developed a system of Martian measurements for the novels, he also drew maps for his own reference while writing, which used the Martian Haad. Martian measurements include the following
Unit Martian Imperial Metric
1 Sofad 11.68+ inches 0.2967 m
10 sofads = 1 Ad 9.75- Feet 2.97 m
200 ads = 1 Haad 1,949.05 Feet 594.07 m
100 haads = 1 karad 36.92 English miles 59.407 km
c. 2.709 Haads 1 English mile 1609 m
c. 1.683 Haads 0.621 English miles 1000 m

Clothing

The Martians wear no clothing other than jewelry and leather harnesses, which are designed to hold everything from the weaponry of a warrior to pouches containing toiletries and other useful items; the only instances where Barsoomians habitually wear clothing is for need of warmth, such as for travel in the northern polar regions described in The Warlord of Mars

.

This preference for near-nudity provides a stimulating subject for illustrators of the stories, though art for many mass-market editions of the books feature Carter and native Barsoomians wearing loincloths and other minimal coverings, or use strategically placed shadows and such to cover genitalia and female breasts.

Fauna

It appears that most of Burrough’s Martian creatures are roughly equivalent to those found on Earth. Though in general, most seem to have multiple legs and all are egg-laying.

“Insects”, "reptiles" and "birds"

  • Sith: A giant, venomous hornet-like insect endemic to the Kaolian Forest.
  • Reptiles: Are described as repulsive and usually poisonous, and include
  • Darseen, a chameleon-like reptile.
  • Silian, an Antarctic sea-monster found in the Lost Sea of Korus.
  • Birds: Burroughs tells us that Martian birds are brilliantly plumed, but the only species actually described is the enormous Malagor, native to the Great Toonolian Marshes.

“Mammals”

The mammal equivalents all have fur, and both domestic and wild varieties are described by Burroughs.

Domesticated

  • Sorak: A small six-legged creature, equivalent to a cat.
  • Calot: A large dog-like creature with a frog-like mouth and three rows of teeth. John Carter has his own calot, named Woola, who is his faithful companion during The Warlord of Mars

Race

Race is a constant theme in the Barsoom novels and the world is clearly divided along racial lines. White, Yellow, Black, Red and Green races all appear across the novels, each with particular traits and qualities which seem to define the characters of almost every individual within them. In this respect, Burroughs' concept of race, as depicted in the novels, is more like a division between species. The Red and Green Martians are almost complete opposites of one another, with the Red Martians being civilized, lawful, capable of love and forming families, and the Green Martians being savage, cruel, tribal and without families or the ability to form romantic relationships.

Religious deception

The Barsoom series features a number of incidences of religious deception, or the use of superstition by those in power to control and manipulate others. Burroughs is particularly concerned about the hypocrisy of religious leaders. This is first established in A Princess of Mars

, on this occasion manipulating a temple idol to control followers.

Burroughs continued this theme in his many Tarzan novels. Burroughs was not anti-religious; however, he was concerned about followers placing their trust in religions and being abused and exploited, and saw this as a common feature of organized religion.

Excessive intellectualism

While Burroughs is generally seen as a writer who produced work of limited philosophical sophistication, he wrote two Barsoom novels which appear to explore or parody the limits of excessive intellectual development at the expense of bodily or physical existence. The first was Thuvia, Maid of Mars
Thuvia, Maid of Mars

: "channels"). This was mistranslated into the English as "canals" which, being artificial watercourses, fueled the belief that there was some sort of intelligent extraterrestrial life on the planet. This further influenced American astronomer Percival Lowell

Percival Lawrence Lowell was a businessman, author, mathematician, and astronomer who fueled speculation that there were canals on Mars, founded the Lowell Observatory in Flagstaff, Arizona, and formed the beginning of the effort that led to the discovery of Pluto 14 years after his death...

.

In 1895 Lowell published a book titled Mars which speculated about an arid, dying landscape, whose inhabitants had been forced to build canals thousands of miles long to bring water from the polar caps to irrigate the remaining arable land. Lowell followed with Mars and Its Canals (1906) and Mars as an Abode of Life (1908). This formed prominent scientific ideas about the conditions on the red planet in the early years of the 20th century. Although Burroughs does not seem to have based his vision of Mars on precise reading of Lowell's theories, as there are a number of errors in his ideas which may suggest he got most of his information from reading newspaper articles and other popular accounts of Lowell's Mars.

The concept of canals with flowing water and a world where life was possible were later proved erroneous by more accurate observation of the planet, and later landings by Russian and American probes such as the two Viking missions

Another Mars novel, dealing with benevolent Martians coming to Earth was published in 1897 by Kurd Lasswitz, Auf Zwei Planeten. It was not translated until 1971, and was thus unlikely to have influenced Burroughs, although it did depict a Mars influenced by the ideas of Percival Lowell.

These include Mars being an ancient world, nearing the end of its life; being the home of a superior civilization, capable of advanced feats of science and engineering; and a source of invasion forces, keen to conquer the Earth. The first two tropes were prominent in Burroughs' Barsoom series. Burroughs, however, claimed never to have read any of H.G. Wells' books. Lowell was probably the greater direct influence on Burroughs.
