|History of the World of Avatar|
The history of this world can be roughly divided into two parts, the time before the Avatar and the time of the Avatar. Prior to the Avatar's creation, lion turtles served as the protectors of mankind, allowing the humans to erect cities atop their shells. Whenever the inhabitants of their cities would venture into the Spirit Wilds, the creatures would bestow the people with the ability to bend the element the turtle was affiliated with; the power was to be returned upon their reentry to the city. However, after the creation of the Avatar, the lion turtles denounced their roles as protectors of mankind, and the people were left to make their own homes scattered across the world, which eventually led to the division of the world into the four nations.
The most notable historical event that took place during the adventures of Team Avatar was the Hundred Year War. The major events highlighted during the time of Korra's Team Avatar are the Anti-bending Revolution, which was followed by the events surrounding Harmonic Convergence. Some time before and during Korra's era, the term "modern" was used to describe how the world of Avatar came into an industrial age.
To further clarify the often confusing timeline in Avatar: The Last Airbender, this timeline and other articles date events as years before the Air Nomad Genocide (BG) and years after the genocide (AG). 0 AG is the year Fire Lord Sozin used the power from Sozin's Comet to begin the Hundred Year War with the Air Nomad Genocide and serves as an epoch for the dating system.
Further notes about the system:
- 0 AG began in winter, but with spring coming soon. This satisfies both the solar calendar and the Chinese Lunar Calendar. Sozin's Comet arrived at the end of the eighth month (solar or Chinese) of that year, in order to satisfy the "end of summer" term used by Roku.
- Aang emerged from the iceberg during winter in late 99 AG and the final battles of the war occurred in the eighth month of 100 AG.
- Almost all characters turned their present ages in 99 AG, as no birthdays except for Yue's have been shown in the series. For example, Katara turned fourteen years old in 99 AG and was nearly fifteen by the end of the War.
- The only birthdays known to have occurred are those of Yue, who turned sixteen in early 100 AG, in late winter, and of Iroh's son, Lu Ten, who was of unknown age when killed during the war, but whose birthday was during the spring.
- As Toph's birthday is unknown, Toph could have turned twelve in either 99 AG or 100 AG. Therefore, her given year of birth (88 AG) may be inaccurate.
- Dating for some of the events between Aang's awakening at the Southern Water Tribe and Aang's arrival at the Northern Water Tribe may be inaccurate, as it is unknown whether the Solar calendar or Chinese Lunar calendar is being used.
The Chinese zodiac is also included. It revolves around the mathematical cycle of twelve animals. The animals are listed here in order.
On the second ring of Wan Shi Tong's calendar, sixteen era names are visible. However, it is unclear how these are used in the dating of the Avatar world. The era during the date of the eclipse was the Ri Wu era.
- Note: These definitions are very loosely based on the characters, as many of the combinations are difficult to understand. Some of the characters are no longer used in modern Chinese.
1. Ri Wu
9. Yun Zhen
The first character in these two-character words has a radical (one of the 214 ideographic elements in Chinese writing used in combination with phonetics to form thousands of different characters) that represents one of the four elements, and rotates in the order air, water, earth, and fire.
- 气 — the "air" radical, used in characters related to gas
- 氵 — the "three drops of water" radical, used in characters related to liquid
- 土 — the "earth" radical, used in characters related to dirt, earth, mineral, etc.
- 火 — the "fire" radical, used in characters related to fire, heat, etc.
The current Ri Wu era, for example, uses the air radical (气). This system might therefore be based on the Avatar Cycle, with the era changing upon the death of each Avatar. If this is the case, Aang would be living during the Ri Wu (Superior military) Era, Roku during the Zhuo Guang (Brilliant light) Era, Kyoshi during the Yuan Zheng (Bastion of righteousness) Era, and so on. This would also mean Korra would be living during the Chun Tai (Honest and exalted) Era.

- c. 9,832 BG — Year of the Dog

First Age of the Avatar (c. 9,829 BG — 171 AG)
Before war (c. 9,829 BG — 1 BG)
- Unknown date before 345 BG
- In the advent of the Avatar, the lion turtles collectively decided that their task as protectors of mankind was done and that they would no longer grant any more bending powers.
- The humans begin to wage war against each other, forcing Wan to intervene in order to maintain peace. His efforts, however, are of little success. The violent conflicts continue until his death and beyond. The next Avatar is born into the cycle after Wan's death.
- Wan Shi Tong brings his library from the Spirit World into the physical world.
- The four bending arts are proliferated across humanity, giving way to the establishment of the four nations.
- Humanity splits into the four nations, each divided by the respective elements. The Air Nomads learn the art of airbending from the flying bison, the Earth Kingdom learn the art of earthbending from the badgermoles (Oma and Shu being the first known humans to earthbend), the Sun Warriors learn the art of firebending from the dragons, and the Water Tribes learn the art of waterbending by observing the pull of the moon on the ocean tides.
- A group of waterbenders from the Northern Water Tribe construct a large city out of ice in order to unite the various tribes inhabiting the North Pole region.
- Following a civil unrest, the Water Tribe —which was originally centered around the North Pole— splits into two groups: one stayed at the North Pole, while the other group went out to settle the South Pole. Relations with their sister tribe were later healed, and the two tribes would gather together at annual New Moon celebrations.
- A large group of waterbenders from the Southern Water Tribe, who are wandering through the Earth Kingdom, discover the Foggy Swamp and, comfortable with the large amount of water there, decide to stay, forming the Foggy Swamp Tribe. The Southern Water Tribe never learns of this offshoot and the Foggy Swamp Tribe itself later forgets its own origins.
- The Sun Warriors gradually fade into obscurity as their civilization declines, leaving many ruins across their island archipelago. The Sun Warriors are believed to have gone extinct, though in reality a handful hiding in the ruins would continue their culture for centuries. The art of firebending, however, was passed on to the other inhabitants of the islands. These would gradually coalesce into the "Fire Nation". Originally the Fire Nation was a spiritual people ruled by Fire Sages, much as the Air Nomads were led by their monks. Over time, however, one sage rose to prominence above the others, ruling the Fire Nation as a sovereign, and the office became hereditary, beginning the line of Fire Lords.
- The vast Earth Kingdom is gradually united under the political authority of the city-state of Ba Sing Se. The King of Ba Sing Se becomes Earth King, overlord of all of the smaller kingdoms within the Earth Kingdom, some of which retain their own hereditary lordship.
- Avatar Yangchen of the Air Nomads is born in the Western Air Temple, after the death of her predecessor. Her reign as Avatar is a peaceful one, due to her fierce dedication to keeping balance and serving the world. She dies around 345 BG,[nb 1] and Avatar Kuruk is born in the Northern Water Tribe.
- Avatar Kuruk tries to kill Koh, the Face Stealer, as revenge for stealing the face of his fiancée Ummi. This event is confusing to place chronologically, as if Koh's description of the event is taken literally, it would have happened c. 800-700 BG, over three hundred years before Kuruk's death.
- 312 BG — Year of the Dragon
- Avatar Kuruk dies; Avatar Kyoshi of the Earth Kingdom is born.
- c. 270 BG — Year of the Dog
- Avatar Kyoshi kills the warlord Chin and founds Kyoshi Island; the War of Chin the Conqueror ends with the victory of the Earth Kingdom government. The 46th Earth King restores his reign over the whole Earth Kingdom, though civil unrest begins to spread on the continent. The day of Chin's death is remembered as Avatar Day in Chin Village and Kyoshi Day on Kyoshi Island.
- Sometime after this event, a peasant uprising in Ba Sing Se spurs Kyoshi to create the Dai Li. In the process, the Earth Kingdom is turned into a constitutional monarchy.
