Timeline of Avatar: The Last Airbender and The Legend of Korra.

To further clarify the often confusing timeline, 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.


Ancient Times

    Before the Era of Raava (before c.19, 829 BG) 
  • Tui and La manifest in the physical world, assuming mortal forms as koi fish.
  • The Mother of Faces gives birth to Koh, the Face Stealer; however, they later become separated.

  • Humans begin to build their cities on the shells of lion turtles to protect themselves from the dangers of the Spirit Wilds. Whenever the people have to venture into the wilds to collect food, the lion turtles bestowed upon the hunters the ability to control one of the elements. Eventually, the majority of the cities lost contact and knowledge of each other's existence, and developed unique cultures.

First Age of the Avatar (c. 9,829 BG — 171 AG)

    Before Avatar Kyoshi (c. 9, 829 BG — 312 BG) 
Unknown date before c. 3,829 BG
  • As humanity left the cities established on the lion turtles, they begin to come in to contact with each other. The different peoples 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.[
  • The Air Nomads learn the art of airbending from the flying bison, and the Northern Air Temple is built.
c. 3,829 BG — Year of the Rabbit

830 BG — Year of the Tiger
  • A past Avatar defeats Hundun and mortally wounds his brother, forcing the conjoined twin kings to retreat to the Spirit World.
Unknown date before 345 BG
  • Wan Shi Tong's Library is brought from the Spirit World into the physical world.
  • The people of the later Earth Kingdom learn the art of earthbending from the badgermoles (Oma and Shu being the first known humans to use specific earthbending techniques), 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 Warrior civilization flourishes, learning firebending from dragons. They operate under a tribal chiefdom led by a single chief. They eventually fade into obscurity, hiding in ruins, and are believed to be extinct. The rest of the Fire Islands archipelago is influenced by their culture, and the islanders carry on the art of firebending.
Warlords battle each other for land in the disaggregated Fire Islands. One of them, Toz, orders the abduction of all of the children of the village that refused to provide him with tribute. The children are never seen again, causing their mothers to die from sadness and become Kemurikage spirits. The Kemurikage exact their vengeance by taking the children of the warlord and his men, leading to the collapse of Toz's regime as his men abandon him out of fear of the dark spirits.
  • At some point, several members of the Bhanti Tribe venture from their island, located in the southern region of what would later become the Fire Nation archipelago, to the other nations, where they become sages,[23] most notably the Fire Sages and Earth Kingdom sages. While the former maintain their spiritual traditions, the latter gradually devolve into de facto officials.
  • Unification wars of the Fire Islands: A man manages to defeat the remaining warlords and bring them to justice, thus uniting the Fire Islands into the Fire Nation, under himself as the first Fire Lord, leader of the spiritual Fire Sages. The Fire Lord and the Fire Sages lead a spiritual rule, much as the Air Nomads were led by their monks. Over time, however, the Fire Lord accumulated political power, ruling the Fire Nation as a sovereign, and the office became hereditary, beginning the line of Fire Lords.
  • Oma founds the city of Omashu after the death of her lover Shu.
  • 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.
  • The Fire Nation's navy is forbidden to fly military colors in the Eastern Sea during the 22nd Earth King's reign.
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. Among her most notable deeds were striking a deal with the spirit Old Iron and signing a treaty with the Fifth Nation.Sometime in the 4th century BG

Sometime between 345 BG and 312 BG
  • When Kuruk attempts to master the Avatar State for the first time, he accidentally destroys an entire island; there were no fatal casualties.
  • 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 birth.

312 BG — Year of the Dragon

Sometime between 305 and 296 BG
  • Fifth Nation leader Tulok is succeeded by his daughter Tagaka. She proves to be an exceptionally capable pirate queen, earning a fearsome reputation and making the Fifth Nation the most powerful pirate fleet in the world. At some point, she defeats the Earth Kingdom's navy in battle and kills the last admiral of Ba Sing Se in a duel.
