Wookiee / Legends The Wookiees , whose name for themselves translated to the People of the Trees , were a species of tall , hairy humanoids that were inhabitants of the planet Kashyyyk . One of the most noteworthy members of the species was Chewbacca , Han Solo ' s best friend and co - pilot , who played a vital role in the Galactic Civil War and afterwards . A race of arboreal mammals , the Wookiees lived in treehouses nestled in the canopy of the towering wroshyr trees . Despite their fearsome appearance , they were usually gentle , although they were prone to devastating fits of rage when provoked . Biology and appearance . A race of towering , hairy bipeds , the Wookiees were one of the most recognizable species in the galaxy . They were renowned for their great strength , their intelligence , their loyalty and their short temper . Due to their appearance , they were sometimes referred to as " walking carpets . " Physiology . The Wookiees of the jungle planet Kashyyyk were shaggy sentient beings whose countenance was considered impressive by many other species . They were humanoid in shape , with a head , a torso , and four limbs , and they stood 2 . 1 meters on average . Their upper limbs , or arms , ended with hands sporting four fingers plus an opposable thumb that allowed them to grab things . Being a species of tree - climbers , Wookiees had a strong back , dexterous hands and thick calve muscles . For the same evolutionary reasons , they also possessed curved retractable claws that sprouted from hidden sheaths in their fingertips with the flex of a muscle . Their heads featured a pair of forward - facing eyes , the color of which ranged from blue to brown , with some individuals having green , yellow , golden or red irises . The Wookiees ' nose was very sensitive and would provoke some sort of olfactory delirium in the presence of meat . Additionally , the Wookiee ' s mouths were filed with sharp fangs that could puncture even the durable scaly skin of the Trandoshans , their ancestral enemies . The Wookiees were also good swimmers , which was reflected by their powerful thighs . But their most striking physical feature in the eyes of the non - Wookiees was their uniform coat of water - shedding hair , the color of which ranged from black to brown according to the subspecies . In fact , the word " Wookiee " was in fact a catch - all term referring to a number of related races that could be distinguished primarily by their fur . The most common subspecies were the Rwook s , who came from the region of Rwookrrorro and whose hair was typically brown , red and chestnut . Although albino Wookiees were rare , they were not unheard of . However , such a birth was generally held to be a bad omen , as white hair did not blend in with the earth tones of their forest surroundings . They breathed oxygen from Kashyyyk ' s atmosphere through their lungs , and were among the variety of species that could develop asthma . Their immense lung capacity allowed them to blow their Kashyyyk clarions , a feat that a Human being could not accomplish . The Wookiees were also susceptible to the Blackwing virus , an infectious viral agent that attacked biological tissue and transformed its victims into zombies . The Wookiee ' s natural habitat was the canopy of the wroshyr trees . Those towering vegetals existed in over 1 , 000 different varieties , most of which reached kilometers in height , while some only attained 300 - 400 meters . Wookiee families lived in treehouses nestled in the crowns of the wroshyrs . Those dwellings often consisted of circular structures of unpainted wood mounted around the tree trunks , sometimes with several stories and a veranda . The most luxurious and elaborate houses were built directly into the trees . Villages were held up by branches only , without the help of repulsorlifts or any other modern technology . Like many other humanoids , the Wookiees had two sexes ; male and female . Female Wookiees had six breasts and gave birth to live - born young , with their gestation period nearly a year long . Wookiee pups were large at birth , averaging slightly less than one meter . After birth , a Wookiee grew very fast , fully conscious and able to walk unassisted within one standard year . During the course of maturation , the individual would grow to about 2 meters , with exceptionally tall individuals attaining 2 . 3 meters . However , cases of nanism were rumored to exist , and very old Wookiees tended to shrink , becoming as short as 1 . 70 meters . Life cycle . Wookiees were a long - lived people , with a lifespan of several standard centuries . While they outlived many other beings , the Wookiees did not live as long as other species such as the millennial Gen ' Dai . Infant Wookiees would remain in the nursery ring s , where they learnt how to interact within their society and were taught to appreciate Kashyyyk ’ s wildlife . At the end of each school day , the parents would take their pups home so they could create and maintain a sense of family . Later in life , the children would stay home full time with the rest of their kin , and were given their first responsibilities in life in the form of housekeeping chores . Around the age of twelve , the males would perform an initiation ritual that made them enter young adulthood . In most parts of Kashyyyk , incumbents to the coming - of - age ritual had to gather silk fibers from the center of a carnivorous syren plant . In other regions of the planet , young males took the Test of Ascension , known as " hrrtayyk " in Wookieespeak . During that ceremony , the youth was expected to unlock his rrakktorr , or inner strength , by learning how to survive in the Kashyyykian Shadowlands , the dangerous ground level of the forests . From the age of 18 , the Wookiees were viewed as full - fledged adults , and were considered in their prime around the age of 200 . Throughout this lengthy period , Wookiees were expected to embrace a career and find a regular source of income so they could marry and found a family of their own . Subsequently , Wookiees were qualified as " middle - aged " by 301 – 350 , " old " by 351 – 399 and " venerable " at 400 . Elderly Wookiees were normally cared for and admired for their accumulated wisdom . Behavior . Wookiees are usually calm , gentle and mild - mannered , but not when they are provoked . They are also known to be sore losers . If one loses a bet , or a game , then the Wookiee may tear off the limbs of the person who beat them . It is usually considered wise to avoid upsetting them . Society and culture . Status . Wookiee marriage was based on sexual monogamy . Once married , the couple mated for life and would usually raise two or three pups , although there was no firm rule on that matter : the famous Chewbacca himself begat an only child , Lumpawaroo . It was uncontroversial for a Wookiee father to leave the planet for long periods of time and entrust the education of their offspring to their mate and older kinsmen . The Wookiee society was a patriarchal one , with a complex lineage structure . Nuclear families were regrouped in clanic structures , and a system of inter - clan alliances and enmities existed . Wookiees greatly valued honor and loyalty . Therefore , their notion of " family " encompassed much more than just blood ties . A part of that most sacred tradition was the social institution of life debt : when a Wookiee ' s life was saved by someone else , regardless of the species , they would frequently devote themselves to a lifetime of service to their savior and their family . Through the mechanism of the life debt , the People of the Trees used to develop unbreakable bonds with their boon companions and true friends , forming a " honor family . " As regards politics , the numerous cities scattered across the surface of Kashyyyk were each led by a Chieftain , who oversaw the civil and military matters of his community . Those Chieftains , also referred to as Elders , occupied a high position at the local scale , and they were entitled to cancel the celebration of sacred holidays . At planetary level , the entire world was ruled over by a King coming from a patrician family and whose court was held at the Royal City . One of the Wookiee monarch ' s roles was to determine Kashyyyk ' s stance in time of interplanetary war . When the Galactic Republic still existed , and Kashyyyk was part of it , the Wookiees were represented before the Galactic Senate on the planet Coruscant . The Wookiee senator was aided in his duties by a staff of Elders who took meetings with him in the Senate Tower . Diet . The People of the Trees were omnivores . While they were perfectly capable of gathering wild plants ( like the wasaka berries ) or even cultivating domesticated varieties ( such as the onion - like chyntuck ) , their lives in the canopy of Kashyyyk prompted them to consume essentially meat . Wookiee cuisine relied heavily on spices . Because of this , many dishes were not suitable for Humans as they could damage their gullet and stomach . Like many other species , Wookiees consumed potent alcohol - based beverages , including the accarragm , the cortyg brandy , the garrmorl , the grakkyn and the Thikkiian brandy . Those spirits were too strong for Humans , who would become severely intoxicated after consuming them . Technology and trade . From an early age , Wookiees were trained to use their dexterous hands for carving . They would learn to fashion everyday objects such as tools , musical instruments and household items . Some would also carve wood en toys , either as gifts for their younglings or just for leisure . An old saying stated : " Give a Wookiee a knife and send him into a forest in the morning , and by evening he would have carved you a table to eat dinner on — and a house to put it in . " Whereas some outsiders qualified their works as art , the Wookiees viewed their innate talents as mere survival skills , and they had no word for " artist " in their various languages . While they appeared to have a low technology level to outsiders , the Wookiees were in fact quite comfortable with modern technology . In fact , their ability to fuse modern conveniences and natural resources was second to none . They could easily mend and maintain modern starcrafts , and were even known to effect temporary repairs of hyperdrives with pieces of hardwood . The wood of the wroshyr tree was so flexible and strong that it could be used to build starship hulls — although in conjunction with deflector shield skins . Throughout history , the outstanding technical ingenuity of the Wookiees aroused covetousness . Additionally , while distant from Coruscant , Kashyyyk was close to hyperspace routes known only to the Claatuvac Guild , a group of Wookiee cartographers and navigators whose knowledge was a source of envy . Combat and war . Unlike other species like the neighboring Trandoshans or the Yinchorri , the Wookiees were not warlike . When peaceful , they had the reputation to be gentle and benevolent . However , their tempers were fiery , and an infuriated Wookiee could erupt in a fit of berserker rage that only ceased when the source of their anger was damaged enough to their satisfaction . Though they were feared as opponents , Wookiees did not use any well - defined style when fighting unarmed . To outsiders , it seemed they simply charged forward , swinging their arms and crushing their targets with their massive fists . That reputation did not stop the Wookiee Rrawkee from starting a wrestling academy on the world of Cularin during the Clone Wars . Even more terribly , Wookiees also had the justified reputation of ripping the arms of their enemies out of their sockets , which was known to occur in instances of losing a game . That state of racial rage served as the basis of the deal - slang expression " wookinate " , which referred to the rendering harmless an enemy using excessive force — obviously referring to the great physical strength that provided the essence of Wookiee combat . In addition , an exhausted Wookiee can be considered even more dangerous in a fight than a fully rested one . Solo at one point when writing notes in the " " implied that Wookiees had enough physical strength to rip a stormtrooper ' s head off even while the helmet was latched on . However , despite their great physical strength and ferocious tempers , the Wookiees were not willing to fight for trivial pretexts . When arguing in public , two Wookiees would engage into a duel of stomping and posturing . Whichever of the two fighters who made the strongest impression was considered to have won the argument . Still , the influence of the crowd taking sides would sometimes infuriate the contenders , turning the otherwise harmless stomping competition into a real fight . Even when engaging in real combat , the Wookiees held true to their code of honor , under which claws were never to be used for fighting . A Wookiee who used his or her claws for combat would be labeled a " madclaw " and exiled . Some were also charged by tradition of killing those members of their kind that engaged in the practice of using their claws in combat , as the act dishonored their race . Contrary to their rudimentary methods of hand - to - hand combat , the Wookiees used their craft to produce unique quality weapons . They typically eschewed standard blasters and grenades in favor of bladed weapons , such as ryyk blades . Their trademark , however , was the powerful bowcasters — a crossbow - like , single - fire weapon , which physically weaker species could not use effectively . Language . The Wookiees spoke an array of dialects collectively known as Wookiee language , all of which consisted in a combination of barks , roars , moans and growls . The most common was Shyriiwook , often nicknamed Wookieespeak in Basic , the literal meaning of which was tongue of the tree people . As a trade language , Shyriiwook was the most well - known Wookiee dialect outside Kashyyyk , and most strangers assumed that there was only one Wookiee tongue . Other known dialects were Xaczik , spoken on the Wartaki Islands , and the Thykarann , which was richer in technical vocabulary . The construction of their vocal apparatus , however , prevented the Wookiees from speaking Galactic Basic Standard , or any other language that involved a high degree of vocal nuance . Nevertheless , they were quick learners and could easily grasp the various foreign languages they encountered . History . Early history . The Wookiees were largely believed to have originated from the planet Kashyyyk , which was part of the Kashyyyk system in the Mytaranor sector of the Mid Rim . However , various pieces of lore had different versions on how they became the dominant species of their world . According to Wookiee legend , the first Wookiees on Kashyyyk were visitors , either in the form of pioneers or refugees . Their own records were vague on the subject and they rarely spoke on this topic . Conventional wisdom held the view that the Wookiees were simply the most capable climbers in a hostile ecosystem that was full of predators . Their capacity to move higher up the trees allowed them to avoid their natural predators helping them to not only survive but even evolve further . Despite either view , no records suggested that there was ever a time when the Wookiees did not populate the surface of Kashyyyk . Some reports indicated that Wookiees evolved on their homeworld around 2 , 000 , 000 BBY where they established dominance in their ecosystem as climbers of the wroshyr trees . Their world was one of the many planets that fell under the dominion of the Infinite Empire and its surface was terraformed by the Rakata for agricultural purposes . However , the collapse of their empire left the machines unattended and resulted in the abnormally large foliage with it being theorized that these machines led to the accelerated evolution of various native species . During the reign of the Infinite Empire , a number of Wookiees were taken from their homeworld and transported to the Rakatan Archipelago where slaves populated worlds such as Malata . Inbreeding amongst these slaves led to sickly genetic deformities with the Wookiees of Malata displaying a stoop - shouldered , hairless form with long front incisors used to gnaw timber thickets . Following the Great Sith War , the planet Kashyyyk was discovered by the Czerka Corporation whose investments into the Galactic Republic ' s rebuilding program led to the Galactic Senate awarding them this world . This was under the justification that they had discovered the planet and thus were the rightful owners of it . After occupying Kashyyyk , Czerka declared that that there were no sentient inhabitants to Kashyyyk and ignored the native inhabitant ' s designation of the planet . They named the planet first " G5 - 623 " and then , after a poll of stockholders , " Edean " . Once they took control , the corporation went against the wishes of the Wookiees and even began allowing slavers to hold a free reign over the native inhabitants . As the planet was deemed to hold little value , it managed to escape the devastation of the Mandalorian Wars and the Jedi Civil War with only Czerka maintaining control over it . Their occupation was brutal and oppressive with the company treating the Wookiees as less than sentient whilst exploiting the world ' s native population and resources in order to gain profit . The corporation further ensured its foothold on the populace by making use of collaborators amongst the Wookiees and managed to get the support of Chuundar who had risen to the position of Chieftain . Czerka control of " Edean " was disrupted when , in 3956 BBY , the enslaved Wookiee populace overthrew the local corporate headquarters with the help of Revan and drove all outsiders off the planet . Several thousand years before the Battle of Yavin , the planet was visited by scouts from the neighboring world of Trandosha who were seeking sites to form new colonies . The Trandoshans were driven off by the Wookiees and forced to leave a single starship behind which gave the inhabitants of Kashyyyk the necessary jump – start in order to reach the stars . The inquisitive Wookiees easily managed to disassemble the vessel , analyze the components and eventually replicate it . This led to the first Wookiee explorers setting off into the black depths of space . In time , their explorations led them into contact with Corellian traders who had established trade relations with the Trandoshans but were not willing to ally with them against the Wookiees . This in turn led to trade negotiations between the Corellians and Wookiees but quickly devolved into the former exploiting the latter . An end to this state of affairs came when the Alderaanian Diplomatic Corps became involved in the incident who petitioned the Galactic Republic for a Senate seat to be created for the inhabitants of Kashyyyk paving the way for it to becoming a member of the Galactic Republic . After becoming a member of the Republic , the Wookiees dissolved the unfair treaty with the Corellians and formed a new equitable trade agreement with them . In addition , they began making treaties with other worlds and new species ; this saw them purchasing hyperdrive technology from the Duros , opening Wookiee cultural studies programs in Alderaan ' s finest universities and trading with the Verpine for the state of the art manufacturing processes . Within the Senate , many politicians spoke admirably of the " " wisdom of the Wookiees " " and they were perceived as a race that were in touch with The Force as they had managed to integrate nature and technology on their homeworld . Kashyyyk became a distinguished member of the galactic community . At least one Wookiee , the Jedi Master Tyvokka , became part of the Jedi Order , and by 32 BBY , Kashyyyk had diplomatic relations with the planet Naboo . During the last decades of the Republic , Senator Yarua represented both Kashyyyk and Trandosha , home of the reptilian Trandoshans . Rise of the Empire . However , the Trandoshans resented their Wookiee neighbors ; after some of them allied with the Trade Federation in the colonization of Alaris Prime , they also attempted to assassinate Yarua in 32 BBY . In 23 BBY , a Wookiee vessel was attacked over a moon of Trandosha , resulting in a Wookiee blockade of Trandosha . Peace talks to resolve the issue were conducted 22 BBY , under the mediation of Jedi Master Oppo Rancisis , but failed when it was revealed that the Trandoshans were pushing for Senatorial representation with Trade Federation backing . During the Clone Wars , the Wookiees attempted to remain neutral at first . It was only after the death of Prince Rikummee at the hands of Separatist droids that King Grakchawwaa led his people into the war on the side of the Republic . Later during the Clone Wars , the Confederacy invaded Kashyyyk . Conquering the planet would prove an asset since it would enable the Separatists to control hyperspace route planning and use the Wookiee ' s secret routes to disrupt galactic trade and communication . In response , the Republic dispatched a task force led by the longtime Wookiee - friend Master Yoda to defend Kashyyyk . There , a combined force of clone troopers and Wookiees repulsed the Separatist droid invaders and their Trandoshan allies at the Battle of Kashyyyk . However , victory was short - lived . With the rise of the Galactic Empire , the Jedi were branded enemies of the Republic and hunted down by the New Order . The former clone troopers , now known as stormtroopers , then took over Kashyyyk and placed it under martial law . In response , the Wookiees rebelled against their new oppressors . In 19 BBY , the Empire enslaved the Wookiees and bombed their cities on Kashyyyk . Any survivors that attempted to escape the beleaguered world were hunted down by the Trandoshans . It was in fact a Trandoshan official who was responsible for convincing the Empire to exploit the Wookiees as slave labor due to their reputation for being a powerful species . This chain of events saw a joint venture between the Galactic Empire and the Blackscale Clan of Trandoshans with the two establishing the Avatar Orbital Platform that was used in the establishment of transportation as well as sale of Wookiee slaves . During the reign of the Empire , word from Imperial Navy Command claimed that the Wookiee ' s were descended from a herd of banthas that crashed on the planet from a Neimoidian trader ship . When the Trade Federation traced the tracking homing beacon , they discovered a new species on Kashyyyk who were the Wookiees . Later history . At the advice of the Trandoshans , the Empire enslaved the Wookiees for their strength . Wookiee captives were used for countless Imperial projects including the Maw Installation and the Death Stars . However , because of their devotion to their homeworld , many Wookiees would evade the Imperial garrison to revisit their beloved forests for important Wookiee holidays , such as Life Day . After the Battle of Endor , the Wookiees were liberated from slavery by the Alliance of Free Planets . The Nagai also attempted to enslave the species though they were repulsed by the New Republic . Sadly , the peace was short - lived . The Empire , having licked its wounds , quickly reestablished a presence on Kashyyyk and enslaved the Wookiees once more . Around 5 ABY Han Solo and Chewbacca assisted in inciting a revolution among the populace , helped in part by Lando Calrissian , Rogue Squadron , and Admiral Gial Ackbar who took on Grand Admiral Peccati Syn in a pitched fleet - battle in the nearby Sumitra sector . Sometime during the New Republic era , the Sith Lord X1 created a force of Wookiee Clones that he used to fight X2 and the New Republic . The Wookiees were represented by Kerrithrarr in the New Republic Senate and Kashyyyk became key signatory and member world of the Inner Council . The planet also welcomed trade and its city of Thikkiiana became a major exporter of computer technology . However , this made it the target of the agents of the Second Imperium in 23 ABY . A task force under Zekk raided Thikkiiana ' s computer stores for use by the Second Imperium in its war against the New Republic . During the Yuuzhan Vong War , the Wookiees suffered a great loss when Chewbacca was killed on the planet Sernpidal whilst helping refugees flee from the ruined world . A memorial service was held on Kashyyyk in honor for the fallen hero . As the Yuuzhan Vong continued their push towards the Core Worlds , they passed near Kashyyyk though it was spared from their usual conquests . This was despite the fact that the world contained a wide variety of deadly lifeforms would have served as useful genetic stock for the Shapers . Military strategists in the New Republic believed that whilst the Yuuzhan Vong would have used the deadly predators they lacked the time or personnel needed for this task of capturing live specimens . It was believed that once the Yuuzhan Vong Empire had consolidated its holdings , it would have eventually turned its attention to the Wookiee homeworld . This led to the Wookiees preparing its defenses in case of any incursions to Kashyyyk . After the Battle of Yuuzhan ' tar , celebrations took place on the planet . At the time of the Second Galactic Civil War , the Wookiees remained loyal to the Galactic Alliance . This remained in effect until Jacen Solo ' s militant actions turned the Wookiees against him and led to them joining the Confederation as well as being allies of the Jedi Coalition . During the conflict , the Wookiees participated in the Battle of Kashyyyk where they fought against the Galactic Alliance . Darth Krayt ' s Galactic Empire saw danger in Wookiees , but knew better than to enslave the entire species like the previous Galactic Empire did . Instead it cut them off from the rest of the galaxy by having Kashyyyk blockaded and all Wookiee spaceports and shipyards destroyed . No Wookiees were allowed to leave or visit Kashyyyk without an Imperial order and HoloNet transmissions to the planet were completely cut off . Supplies and traders still could come and go , after swearing under penalty of death not to provide Wookiees with information of the state of the rest of the galaxy , but the Wookiees themselves were completely isolated and largely left alone . Behind the scenes . The name " Wookiee " originated in George Lucas ' s film " " . In a line ad - libbed by an actor , a character says , " I think I just ran over a wookiee on the expressway . " There were many early versions of Chewbacca ' s appearance , including one concept art that eventually became the basis of the Lasat . His final appearance in the movie is based on a 1976 piece of concept art by Ralph McQuarrie , which in turn was based on an illustration by John Schoenherr for George R . R . Martin ' s novelette " And Seven Times Never Kill Man ! " , published in the July 1975 issue of Analog . According to McQuarrie , he was told by George Lucas that the drawing was actually from the 1930s . The Schoenherr illustration also includes a weapon that became an inspiration for Chewbacca ' s bowcaster . Wookiees were present in the " Star Wars " saga from George Lucas ' s earliest drafts . In many early versions of the story which eventually became " " , a crucial battle takes place on a planet full of Wookiees . This idea resurfaced in early versions of " " , though Ewoks would be used instead ; in a DVD commentary , Lucas stated that he changed this because he couldn ' t reconcile the " primitive , " Stone - Age race needed for the story with Chewbacca ' s strong technological know - how . In " " , the long - awaited Wookiee army finally appeared on screen . George Lucas once decreed that there can be no more Wookiee Jedi in the Expanded Universe . Notably , Obsidian Entertainment was forbidden to make Hanharr a Dark Jedi because of this restriction . Kirlocca , Lowbacca , and Tyvokka are the only existing Wookiee Jedi characters ( though an unnamed Wookiee in " Edge of Victory : Conquest " appears to be an unknown Jedi student rather than Lowbacca ) , as they were developed before this policy was enacted . The series which was published years after the policy was enacted introduced the Wookiee Je ' daii Ruhr . Lucas himself went back on the " no Wookiee Jedi " rule by including a Wookiee youngling , Gungi , in the " " episode " The Gathering " and its proceeding story arc . Fans of jam bands are sometimes classified as " Wooks " or " Wookiees " due to their stereotype of having unshaven faces , long hair , and lack of personal hygiene . Sometimes people with are said to have Wookism or Wookieeism , though not a commonly accepted term . Wookiees bear a notable resemblance to the phenomena of the , with one issue of Star Wars Tales linking Chewbacca and Han Solo to the adventurous wanderings of Indiana Jones . Chewbacca being linked with Sasquatch was likewise a reference to an event that took place during filming of " Return of the Jedi " , where Peter Mayhew , Chewbacca ' s actor , had to be escorted by people wearing brightly colored vests while in - costume so he would not be mistaken by people who stumbled onto the set as Sasquatch . In the video game " Knights of the Old Republic " , a historical Wookiee figure known as Bacca is spoken of . Apparently , he was the first to discover the existence of life outside Kashyyyk , an occurrence which was caused by the crashing of a probe into the Shadowlands . He forged a blade from the wreckage , a weapon which still appears in Wookiee folklore and myth . In " Star Wars : Galactic Battlegrounds " and its expansion pack , " Star Wars : Galactic Battlegrounds : Clone Campaigns " , the Wookiees were shown with their own aquatic fleet , starfighters , and various mechs / heavy weapons / vehicles , as well as using various small arms besides their bowcasters ( such as missiles and thermal detonators ) . In early publications , the word Wookiee was often spelled as just " Wookie " . The online Star Wars wiki Wookieepedia is named after the species .
