History of the World of Avatar

The Avatar World has an extensive history dating many thousands of years. This article lists historical events in a timeline.

The Avatar World history can roughly be divided into two eras. The first great era was the Era before the Avatar, where its people utilized Energybending to bend the energy within themselves. Eventually people discovered the four elemental bending arts and split into four nations, and over time knowledge of Energybending was almost completely lost. The Avatar appeared in the world to keep peace and balance between the nations, beginning the second era, the Avatar Era. The current Avatar Era has lasted for thousands of years, and there have been over a thousand incarnations of the Avatar. One of the most notable events of the Avatar Era has been The War, a worldwide conflict which lasted for a century.

Dating
To further clarify the often confusing timeline in Avatar: The Last Airbender, this timeline and other articles date events as years before Sozin's Comet (BSC) and years after Sozin's Comet (ASC). 0 ASC is the year Sozin's Comet arrived to begin The War.

Further notes about the system:
 * 0 ASC 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 8th month (solar or Chinese) of that year, in order to satisfy the "end of Summer" term used by Roku.
 * Aang emerges from the iceberg in late 99 ASC, during Winter, and the final battles of The War occurred in the 8th month of 100 ASC.
 * Almost all characters turned their present ages in 99 ASC, as no birthdays except for Yue's have been shown in the series. For example, Katara turned 14 years old in 99 ASC, and is now nearly 15.
 * The only birthday that is known to have occurred is that of Yue, who turned 16 in early 100 ASC, in late winter.
 * As we do not know Toph's birthday, Toph could have turned 12 in either 99 ASC or 100 ASC. Therefore, her given year of birth (88 ASC) may be inaccurate.
 * Dating for some of the events between Aang's awakening at the South Pole and Aang's arrival at the North Pole may be inaccurate, as it is unknown which calendar is being used, solar or Chinese Lunar.

Chinese Zodiac
The Chinese Zodiac is also included. It revolves around a cycle of 12 animals. The animals are listed here in order.

It should be noted that 100 ASC, the year The War ended, was a Year of the Monkey.

Era Names
On the second ring of Wan Shi Tong's calendar 16 era names are visible. However, it is unclear how these are used in the dating of the Avatar world. The current era, judging by the date of the eclipse, is the Ri Wu era.

Before War (Unknown - 1 BSC)

 * Era before the Avatar
 * People bend the energy within themselves rather than the four elements.


 * The four elemental bending arts are discovered, and the people split into Four Nations, divided by the elements. The Air Nomads learn Airbending from the Flying Bison, the Fire Nation learns Firebending from the Dragons, the Earth Kingdom learns Earthbending from the Badgermoles, and the Water Tribes learn Waterbending by observing the pull of the Moon on the tides. Tui and La assume mortal forms as Koi Fish.


 * Oma and Shu become the first Earthbenders, learning the bending art from Badgermoles, and using their Earthbending to find each other in dark tunnels.


 * Avatar Era
 * The "Avatar" is born into the world, one person who can bend all four elements. The Avatar Cycle begins.


 * Unknown date before 312 BSC
 * 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 eventually dies. Avatar Kuruk of the Water Tribe is born in the Northern Water Tribe.


 * Avatar Kuruk tries to kill Koh, the Face Stealer, as revenge for stealing the face of his wife 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 BSC, over three hundred years before Kuruk's death. Being as Kyoshi was the oldest Avatar at two hundred thirty years of age at death, it is possible that Koh's sense of timing is off, or that time runs differently in the Spirit World.
