Hundred Year War

The Hundred Year War, also known as The War and The Great War, was a major global conflict lasting a century that involved all four nations. It was fought between the Fire Nation and the other three nations, the Earth Kingdom, the Water Tribe and the Air Nomads. The Fire Nation, taking advantage of the absence of the Avatar and their military and technological superiority for most of the war, was able to wreak destruction and widespread loss of life in the other nations, including the infamous genocide of the Air Nomads whose Air Temples were falsely presumed to be unassailable to the Fire Nation due to the Air Nomads possessing the sole means of getting to them.

The Hundred Year War was started by Fire Lord Sozin, who wished to expand the Fire Nation into a world-wide empire, and spread what he saw as his nation's prosperity to the rest of the world.

The Hundred Year War ended roughly a year following the reappearance of the Avatar, Aang, due to a combination of efforts of the remaining two nations, the Avatar's group's destruction of the air fleet meant to use Sozin's Comet to deliver the killing blow to the Earth Kingdom, Aang's victory over Phoenix King Ozai, and the newly crowned Fire Lord Zuko's intention to restore peace and harmony among the four nations.

The Fire Nation, following the Avatar's return shifted their strategy to became more aggressive, taking bigger risks to deliver killing blows to their opposition and therefore make any possible intervention by Aang too late. This strategy produced colossal setbacks for the Fire Nation when the Avatar became involved. For example, the Fire Nation launched a massive invasion of the North Pole when they realized that Aang was taking refuge there, and suffered a crushing defeat at the last second when the Ocean Spirit and Avatar intervened. Similarly, an effort to breach the walls of Ba Sing Se utilizing a giant drill was also thwarted. However, simultaneously immense victories were also won such as the surrender of Omashu and the infiltration and conquest of Ba Sing Se.

In the end, the sudden upstart of rebellions in Fire Nation-controlled territory in the Earth Kingdom (including Omashu), the simultaneous defeat of Ozai, the reversal of the conquest of Ba Sing Se by the White Lotus, and weariness of one hundred years of continuous war likely made the people of the Fire Nation very much open to Fire Lord Zuko's rule and his intention to restore peace.

Sozin's plan
138 years ago, Fire Lord Sozin began to feel that because his nation was so fortunate in so many ways, that he should "share" this prosperity with the rest of the world. He spoke about his plan to his best friend, Avatar Roku, and tried to convince him to join him on his quest to expand "the most successful empire in history". Roku vehemently refused to help him and reminded his long-time friend that the four nations were meant to be just what they were: four.

Roku's intervention
"'I'm sparing you, Sozin. I'm letting you go in the name of our past friendship, but I warn you, even a single step out of line will result in your permanent end.' - Roku to Sozin in 'The Avatar and the Fire Lord'."

Years later, however, Roku discovered that Sozin had set up colonies in the Earth Kingdom despite his warnings and went to rebuke him, leading Sozin to attack him. The Avatar subdued the Fire Lord, utterly destroyed his palace and warned him that if he ever acted out of place and attacked the other nations again, he would put an end to him permanently.

Twenty-five years later, Roku's home island was consumed in a volcanic eruption so massive that Sozin could see and feel it from a hundred miles away, and he flew in on his dragon to assist his old friend. The two used their bending to try to contain the lava flow, but they were hindered by poisonous gases, which eventually overwhelmed Roku, leaving him lying on the ground and begging for his old friend's help. Sozin suddenly realized, however, that Roku's death would allow him to fulfill his plans, and he left his old friend to die. The new Avatar was then born into the Air Nomads as Aang.

Twelve years after Roku had died, Sozin used the return of a comet, a celestial event that grants firebender near-unlimited power, to deliver a devastating first blow to the other nations and start the war, setting the stage for the Air Nomad Genocide.

Air Nomad Genocide


Fire Lord Sozin decided to launch his attack upon the arrival of Sozin's Comet. With the power of the Comet, Sozin's firebender armies launched a genocide on the pacifistic Air Nomads in an attempt to capture the new Avatar, Aang, and to halt the Avatar Cycle. This would overcome one of the Fire Nation's biggest obstacles to victory. However, Aang had run away before the attack, thus escaping the carnage. Almost all other Air Nomads were believed to have been killed in the attack, and the remainder ruthlessly hunted and killed as the Hundred Year War progressed, by the end leaving Aang the only known airbender left alive. Sozin would continue searching for Aang up until his death. The Air Nomad Genocide involved mass trooper, tank and balloon attacks on the three temple kingdoms. Thousands possibly even millions of Nomads were slain along with flying Bison and Lemuers.

Spread
After the first strike against the Air Nomads, Fire Lord Sozin and his army began their first assaults into the Western Earth Kingdom. Sozin's main objective was to overcome the Avatar and secure the coastline of the western part of the continent and use it as staging grounds to advance throughout the Earth Kingdom and to supply his forces, Other objectives were to cripple and destroy key Earth Kingdom trading centers to weaken the large Earth Kingdom economy. After several battles, including the Battle of Han Tui and the Battle for Taku, the Fire Nation was able to gain a strong foothold in the Earth Kingdom.

The Fire Nation's war effort was focused at the Western theater through the use of a large portion of the Fire Navy, but Sozin expanded northward and eventually was able to send forces to conduct an attempted invasion of the Northern Water Tribe fifteen years after the Hundred Year War began, which ended in failure due to the North Pole's treacherous landscape. The battle saw ground forces from both the Water Tribe and the Fire Nation confront each other directly.

Middle stages


Fire Lord Azulon took the throne after his father's death. He began to advance south to the Southern Water Tribe and eastward toward the walls of Ba Sing Se. Forty years into the Hundred Year War, the Fire Navy attacked the then-prosperous Southern Water Tribe likely for the same reasons they attacked the Air Nomads: to remove a potential front from the war, and in the possibility that the Avatar might have indeed been killed during the airbender genocide, in which he would be reborn into the Water Tribe. Their first attacks included the bombardment of several Water Tribe villages, but from then on afterwards they restricted their attacks to less costly surprise raids.

Waterbenders across the South Pole fought the firebenders, and the Fire Nation adopted a policy of eradicating Waterbending from the south pole entirely, taking all waterbenders prisoner, leaving the non-benders to fend for themselves. Among these prisoners was Hama, who notably developed a deep hatred for her captors but eventually escaped from captivity whilst waging her own personal war on them in secrecy. The Southern Water Tribe remains weak and the victim of constant raids, teetering on the edge of extinction.

The Earth Kingdom came under many large-scale attacks, with battles such as the Battle of Garsai and the fall of the Hu Xin Provinces furthering the Fire Nation's advances into the Kingdom and putting them in control of the entire northwestern third of the continent. Thousands perished in these massive violent battles.



During the war's ninety-fourth year, the Southern Water Tribe was attacked in yet another minor raid aimed at eliminating any remaining waterbenders. The attackers, the infamous Southern Raiders, were informed that one last waterbender, who happened to be Katara, was left in the Southern Water Tribe, and were given orders to kill her. However, Katara remained undiscovered because, during this raid, her mother Kya turned herself in as the last waterbender in an attempt to protect Katara. Kya was in turn killed, but her heroic act meant that the Fire Nation would never discover the true identity of the last waterbender in the South Pole. Katara would later rediscover the Avatar as an indirect result of her mother's actions.

In the Earth Kingdom theater, the Fire Nation enjoyed more success, conquering every major Earth Kingdom city and stronghold until only Omashu (who hindered any major overland progress in the east) and Ba Sing Se were left. Finally, they reached the walls of Ba Sing Se itself, and the 600-Day Siege of Ba Sing Se began. In its final stages, the Fire Nation even managed to break through the Outer Wall, but their advance ended when their leader General Iroh's son was killed, resulting in Iroh's order to retreat. However, the order was also motivated by the fact his army was fatigued and had been embroiled in continuous fighting for so long.

Hope fades
In recent years, the ferocity of the Hundred Year War eased slightly with the Fire Nation nearing victory. Ozai was crowned Fire Lord upon Azulon's death. Iroh's forces retreated from the area of Ba Sing Se, although they remained in control of the Western Lake where they began construction of the Drill. The Northern Mountains were left alone, allowing refugees to move in.

However, the conquered western shore of the Earth Kingdom was put under tighter control, where General Fong's fortress was the only Earth Kingdom military base left, hidden in a coastal mountain range. Several fortified bases were set up there. Prince Zuko began his search for the Avatar upon his banishment three years before, hoping to reclaim his throne. Zhao, an eager and ambitious naval officer, began plotting the conquest of the Northern Water Tribe. Any attempt at rebellion was dealt with harshly, and the Fire Nation began arresting any earthbenders in their territory, forcing them into slave labor on offshore factories and shipyards.

To add to the Earth Kingdom's troubles, a large number of their villages and cities were now under Fire Nation control, with their native citizens forced to serve the will of the Fire Lord if they were to avoid persecution. Only non-essential territories were left alone. Even though major cities like Ba Sing Se and Omashu remained free at the time, the Fire Nation clearly controlled the majority of the continent, free to prowl almost anywhere in the north and west unopposed.

Team Avatar


The fortunes of the Earth Kingdom and the Water Tribes made a turn for the better with the sudden return of the Avatar and last airbender, Aang, who was rediscovered by Katara. This immediately attracted the attention of both Zuko and Zhao, who chased him across the world. As the Avatar traveled north to the North Pole in an attempt to learn waterbending, Zhao was promoted to Admiral. A small force attacked the Northern Mountains, only to be beaten back in what culminated as the Battle for the Northern Air Temple. However, the defeated force did bring back the Fire Nation an important new invention - the hot air balloon.

Upon discovering that the Avatar had succeeded in reaching the North Pole, Zhao ordered almost the entire Navy to advance on the North Pole. However, the Siege of the North was unsuccessful due to the Avatar's intervention, and the fleet was all but destroyed. Zhao was killed by La, the Ocean Spirit after an unsuccessful attempt to kill Tui, the Moon Spirit, in a bid to neutralize the waterbender's power. With the Fire Nation's main ambition out of the picture and their control of the seas severely weakened, Ozai had his armies continue the slow and steady advances on all the Earth Kingdom fronts, while discreetly sending his daughter to search for the traitorous Iroh and Zuko.

Soon after the defeat at the North Pole, the Fire Nation won a great victory by conquering the city of Omashu, capturing King Bumi in the process, leaving Ba Sing Se the last major Earth Kingdom city unconquered. Though most of the city's population managed to flee under the ruse of a plague, the city itself remained under the control of a Fire Nation governor and was renamed New Ozai by Princess Azula. The loss of Omashu left the route into the southern Earth Kingdom unblocked and defenseless, although the Fire Nation decided to focus most of its military on the Capital, sending only light forces to subjugate the southern villages and townships.

The Fire Nation's next major battle would be at the walls of Ba Sing Se once more. The drill, a powerful and gigantic mechanized siege weapon, attacked the Outer Wall. However, the Avatar had just arrived. Though the machine succeeded in drilling through the Wall, it was destroyed by the Avatar, and the attack failed and the newly-drilled hole blocked with wreckage.

Earth Kingdom falls


Princess Azula, Mai, and Ty Lee, a trio of the Fire Nation Academy's best, infiltrated the capital of Ba Sing Se. Clad in Kyoshi Warriors uniforms, stolen from the warriors after having defeated them in an earlier engagement, Azula infiltrated the court of the Earth King and undermined the Dai Li. She eventually convinced Long Feng to launch a coup d'état against the Earth King. In the end, she double-crossed him and assumed control over the capital. She also succeeded in capturing her uncle and convincing Zuko to rejoin the Fire Nation, clouding his judgment by promising him his father's love. With Ba Sing Se under their control, the Fire Nation was close to victory, with only the tattered Water Tribes and parts of the Earth Kingdom left opposing them. Azula also learned that Ba Sing Se had been planning a major invasion of the Fire Nation home islands on the day of a solar eclipse in late summer, which would briefly leave all firebenders powerless. With the Western Navy still recovering from the Siege of the North, the invasion might have been successful had the Dai Li not arrested the Council of Five. Still, with knowledge that their homeland would still be vulnerable, the Fire Nation made plans to use this to their advantage.

To make matters worse, Avatar Aang was gravely injured in a failed attempt to defeat Azula, who struck him down with a powerful lightning blast. Although Katara was able to revive him, Aang remained in a coma in the following weeks, and he was immediately presumed dead by the entire world. When word of Aang's defeat spread across the globe, the Earth Kingdom and Water Tribes lost hope and the Fire Nation came close to declaring victory in its imperialist war. Aang and his friends traveled into the Fire Nation incognito until the time to strike came again.

Several weeks later, Ozai called a war meeting with his generals. One of them, Shinu, said that while Ba Sing Se had been conquered, a number of Earth Kingdom rebellions arose and that the Earth Kingdom military was still controlling vast swaths of territory mainly in the south, which kept the Fire Nation from claiming ultimate victory in the Hundred Year War. When Zuko said that the Earth Kingdom could endure anything as long as they had hope, Azula said they should "take their precious hope, and the rest of their land, and burn it all to the ground." Ozai, using this idea, planned to use the power of the returning Sozin's Comet to completely destroy the Earth Kingdom.

Though the Fire Nation controlled great swathes of territory they were not unopposed. A small multinational invasion force led by Chief Hakoda of the Southern Water Tribe and the Avatar assaulted the Fire Nation Capital on the Day of Black Sun and they were nearly successful, but their supposed success was actually a carefully planned trap by the Fire Nation. Though they were repelled by the new Fire Nation air force of airships and most of the resistance leaders were captured, they proved that the Fire Nation could continue to be resisted as long as hope was maintained.



However, the Day of Black Sun was not a total failure for those resisting the Fire Nation. During the Eclipse, King Bumi saw the chance he had been waiting for. He broke out of his prison and, with the firebenders unable to firebend, retook the city of Omashu single-handedly. Iroh also broke out of his cell and according to a guard, fought as a "One-Man Army."

Prince Zuko realized the full extent of the Fire Nation's crimes and joined the Avatar so that Aang could learn firebending to fight the Fire Lord. This development only increased the threat the Avatar posed toward the Fire Nation. Coinciding with this, Princess Azula was betrayed by her allies, Mai and Ty Lee after a failed sabotaging of an Escape from the Boiling Rock, badly hurting both her psyche and her leadership ability.

Fire Lord Ozai intended to crown himself Phoenix King prior to the arrival of Sozin's Comet and to have Azula succeed him as Fire Lord. Ozai intended to finish the Hundred Year War by using the comet's immense power to vanquish his enemies, so the Avatar's group, one of the Fire Nation's greatest threats, had to act quickly to prevent this catastrophe.

Fall of leaders


When Sozin's Comet made its return to the world, Ozai launched his massive attack on the Earth Kingdom with his armada of airships. When he arrived at the Wulong Forest, which he quickly proceeded to incinerate, Avatar Aang confronted him. Despite Aang's pleas to end the Hundred Year War peacefully, Ozai attacked him. At first, Ozai and Aang were evenly matched, but Aang refused to go on the offensive due to his belief that all life was sacred. Ozai gained the upper hand, but accidentally smashed Aang into a rock that hit the scar on his back. This opened his seventh chakra, allowing Aang to enter the Avatar State. Using the Avatar State's power, Aang went on the offensive. Despite his enhanced firebending, Ozai was quickly forced to retreat. Aang pursued him, and eventually pinned him down. But just as he was about to deliver the finishing blow, Aang left the Avatar State. Instead of killing Ozai, Aang used energybending to strip him of his firebending.

Azula, after losing the alliance of Mai and Ty Lee, was badly weakened by a state of mental instability. This caused her to lose all trust in everyone, thinking everyone was against her, she then banished all those loyal to her, and in effect, had no protection or allies. This, combined with her subsequent defeat, effectively rendered her unable to fight in the Hundred Year War any longer.

Conclusion


While Aang and Ozai fought, three members of the Avatar's group, Sokka, Toph and Suki, hijacked one of the airships in Ozai's armada. Using an "airship slice" tactic, they successfully destroyed the fleet. The Order of the White Lotus, under Iroh's leadership, successfully retook Ba Sing Se, a colossal defeat for the Fire Nation. Zuko and Katara found and defeated Azula so Zuko could take his place as Fire Lord of the Fire Nation.

With the loss of Omashu, Ba Sing Se, and the fall of their leaders, the Fire Nation Armies found themselves unable to continue the war effort.

Aftermath
"'A hundred years of fighting has left the world scarred and divided. But with the Avatar's help, we can get it back on the right path, and begin a new era of love and peace.' - Fire Lord Zuko in 'Sozin's Comet, Part 4: Avatar Aang'."



After these victories, Zuko was crowned Fire Lord and officially declared the war to be over. At his coronation, Fire Lord Zuko promised before a large audience of the world's citizens that he would dedicate his rule to rebuilding the war-torn world, and that he would do this with the help of his friend and partner, Avatar Aang.

After being defeated by Aang, Fire Lord Ozai was arrested and put in prison. It was recently revealed that Azula has been institutionalized in a mental health facility on an isolated island near the capital.

The world has begun the process of rebuilding. The city of Ba Sing Se has begun rebuilding and even has a brand new tea shop. As Fire Lord Zuko stated, the world has a lot of rebuilding to do, but the war was finally over.

The Harmony Restoration Movement was created as a step toward peace in removing the Fire Nation colonies from the Earth Kingdom. However, after seeing all the hard work his people have done within, Fire Lord Zuko removed his support from the movement. This decision started a confrontation that threatened to throw the world back into war, causing Avatar Aang to intervene.

War capabilities
During the war, it was obvious from the beginning that there was a great disparity in means and effectiveness between the military powers of the four nations.

Air Nomads
The Air Nomads, being pacifistic, had no formal military power, nor any standing means of fighting a war. Being nomadic and reclusive from the world-at-large, they believed that they were for the most part safe from military excursions, as Aang optimistically stated. They possessed no weapons, and whatever they created was hand-made.

Northern Tribe
The Northern Water Tribe was an isolated power that managed to survive mostly unscathed for much of the war because of its remote and treacherous location. Centralized around tribal leaders, and unified by a cultural feeling of unity, the Northern tribe was able to unite in the face of Fire Nation aggression.

The Northern Tribe had a warrior class, as opposed to a standing army. The tribe had a large number of benders able to utilize the surroundings of their home, and a number of non-bending warriors who utilized spears and various weapons made from animal bones. For the majority of the war, women were forbidden from offensive waterbending, restricted to healing, and social convention kept them from being warriors.

While not having a navy, waterbenders used small canoes to surround and neutralize the bulky Fire Nation warships. This worked well against individual ships, or small groups, but was impractical against fleets, and especially the armada assembled by Zhao. These ships were not made for journeys, but for quick response to immediate threats. The northern tribe, like the southern tribe also had large traveling ships made of bones and treated animal skins.

Southern Tribe
Unlike the Northern Tribe, the Southern Water Tribe employed female waterbenders. The Southern Tribe was much more isolated than their sister tribe, and close to the end of the Hundred Year War suffered near extinction. All waterbenders, apart from Katara, were removed from the Southern Tribe during the middle of the war, essentially eliminating the Southern Tribe as a factor in the overall war.

As opposed to the almost impregnable fortress-like city of the Northern Tribe, the Southern Tribe had a much smaller, inland walled-town. Over time this town was reduced to a makeshift village.

By this time, the warriors of the tribe departed for the Earth Kingdom, led by Chief Hakoda.

The Southern Tribe employed sailing ships made of bones and animal skins.

Earth Kingdom
The Earth Kingdom's military might mostly relied upon its sheer size. This proved to be its main disadvantage in fighting a centralized power like the Fire Nation. The Earth Kingdom was composed of a number of provinces loosely controlled by the Earth King at Ba Sing Se. However, most of these provinces had their own local lords, or in cases like Bumi, kings, all of whom paid lip-service to the Earth King, but were in fact for the most part autonomous.

This political divisiveness meant that the majority of Earth Kingdom military retaliation to the Fire Nation was conducted by provincial lords and kings. By the time of the reign of Earth King Kuei, the Earth King had no knowledge of the war, and no control over the military until the Grand Secretariat, Long Feng, was arrested. The Earth King's sphere of influence was limited to the walls of Ba Sing Se itself.

Earth Kingdom military prowess paled in comparison to the tactics of the Fire Nation army. The army as a whole was structured similarly; benders, and then a number of varying sorts of none-bender infantry, such as pikemen and swordsmen. Where as the Fire Nation used mainly machines, along with rhinos for certain terrain, the Earth Kingdom typically employed animal labor, such as ostrich horse cavalry, which had a diverse amount of uses. The only non-animal vehicle shown were stone tanks mounted on caterpillar treads. These tanks were moved via earth-bending, but were versatile juggernauts capable of laying waste to their metal Fire Nation counterparts.

The Earth Kingdom navy utilized wooden ships. The Fire Navy dominated the seas during the Great War, with the Earth Kingdom possessing no seen naval presence, although General How mentioned there still being naval forces during the Council of Five's discussion of the invasion plan.

The Earth Kingdom possessed no air force. The technology was newly founded at the time the Earth Kingdom fell.

Near the end of the Hundred Year War, the multi-ethnic invasion force that invaded the Fire Nation on the solar eclipse possessed several new technological devices, including caterpillar-tread transports, submarines, and a number of smaller inventions devised by Sokka and the mechanist. Most of these were not employed by the Earth Kingdom as a whole at this time.

Fire Nation
The Fire Nation, a relatively small but prosperous empire, possessed technological prowess beyond any of the other nations. By the time the war began, they had metal-based ships, steam-powered engines and machines, the ability to mass-produce standard military hardware, and many other industrial-age based social, economic, and political traits. Numerous factories for metalwork, military construction, and commodities dotted the Fire Nation homeland.

Unlike the Earth-Kingdom, the Fire Nation from the beginning of the war was a centralized power, directly controlled and directed by the dictatorial power of the Fire Lord and his advisers. This combination of unity and technological advancement gave the Fire Nation a distinct edge over its main military opponent, the Earth Kingdom, which still functioned under a feudal system. The Fire Nation military was organized, rigidly controlled, and directed by the Fire Lord and his council of generals. The army was organized into benders, various divisions of non-benders, such as archers, pikemen and swordsmen, and into a domestic national guard. The army employed a variety of war machines, including steam-powered tanks, trebuchet artillery, and the drill.

The navy was structured similarly, possessing several fleets of the most advanced warships in the world, including a domestic defense fleet that formed a large blockade around Fire Nation waters. These ships were steam-powered, and used deck-mounted trebuchets for long-range assault.

Near to the end of the war, the Fire Nation also employed a burgeoning air force of airships and zeppelins, utilizing benders for close-quarters defense, and bombs for air-to-ground bombardment. The zeppelins also featured a forward-cannon for shooting bombs forward at level targets.

The Fire Nation initially had surprise on their side; however, given the intervention of Avatar Roku this was lost to the twenty years between the first established colony, and the death of Roku, which allowed Sozin to pursue his ambition.

Trivia

 * The Hundred Year War's monikers (the Hundred Year War and the Great War) can be perceived as allusions to the real-world wars of the Hundred Years' War (which actually lasted 116 years {1337-1453}) and World War I (the first war involving all the major world powers {1914-1918}).
 * The Hundred Year War is more like World War II (1939-1945) due to the fact it involves world powers and it has more reference to the Pacific War in the Pacific and the Second Sino-Japanese War (1937-1945) between China and the Empire of Japan.
