She was the Avatar before Roku. The major threat to the world in her time was a warlord named Chin the Great and he demanded control of Kyoshi Island (at which time was part of the mainland). She split Kyoshi from the mainland and made Kyoshi Island and killed Chin to keep peace. And it's kind of interesting to know that the person who does her voice also does June the bounty hunter's voice.
Avatar Kuruk, a Waterbender.
And who was before that?
Between Aang, Roku, and Kyoshi, it seems that on average, each Avatar lives about 152 and a half years, so in a thousand years, there must've been about 6 or 7.
Avatar Yangchen was the female, Air Nomad Avatar before Kuruk.
Aang is the current incarnation of the Avatar. He is biologically a twelve-year-old boy, but chronologically he is one hundred and twelve due to being frozen in an iceberg for a hundred years. Katara and her older brother, Sokka, found him and Appa in the frozen air sphere. All the time, Aang likes adventure and fun than doing his jobs as the Avatar. He's a little light-hearted and very moody at times. In the end of the series, he and Katara had a relationship. He successfully defeated the aggressive Phoenix King Ozai by using the knowledge the legendary Lion Turtle taught him, by Energybending. The members of 'Team Avatar' are... Aang, Sokka, Katara, Toph, Appa, Momo, Suki from time to time, and eventually (SPOILER) Zuko.
Tha airbending avatar before Aang was Avatar Yang Chen, and there are lots of statues of her in the series.
Roku - fire Kyoshi - earth Kuruk - water Yangchen - air we dont get told anyone else after that
Avatar Kyoshi
Avatar Kuruk from the Water Tribe.
Chin the Conqueror. Who, "threatened to throw the world out of balance." When he came to claim Kyoshi's home, Kyoshi defeated him.
Avatar Kuruk is the Avatar before Kyoshi and after Yangchen. He is a Northern Water Tribe avatar. Due to his "go with the flow" ways, he lost his fiancée, Ummi, to Koh the Face Stealer.
She was an earth bender.

Avatar Kyoshi died of old age at 230 years, in 82 BC.
there are rumors that Sokka and Suki have a child who is Avatar Korra. Korra lives in the Southern Water Tribe (like Sokka) and she has the same sort of personality as Avatar Kyoshi (Suki is a Kyoshi Warrior)
The known Avatars are Yangchen, Kuruk, Kyoshi, Roku, Aang, and Korra.
