Ba Sing Se(永固城) is a city in the Earth Kingdom.
Ba Sing Se has been hailed as the greatest fortress in any of the four nations, having remained unconquered for centuries prior to the Hundred Year War. During Chin the Conqueror's largely successful campaign to unify the Earth Kingdom under his control, Ba Sing Se was the only territory to remain unconquered besides the peninsula where Avatar Kyoshi lived. Apparently, Chin would rather face the Avatar herself than try his luck at the Great Wall of Ba Sing Se.
Agrarian Zone[]
Just outside of the Lower Ring, between the Outer Wall and the Inner Wall of the city is the Agrarian Zone, a large underdeveloped area that consists of wide open plains of land, used mainly for agricultural purposes. Along with its vital wildlife and crop resources, the Agrarian Zone functions as a massive land buffer between the Outer Wall and the Inner Wall, where all of the Ba Sing Se residents dwell, widening the gap between invaders and citizens if perchance the Outer Wall was ever breached.This area in the city houses many farms belonging to citizens, mostly of the Lower Ring, who live behind the Inner Wall and travel outside to tend to the land every day.
Fall of Ba Sing Se[]
Princess Azula and her friends succesfully entered Ba Sing Se.
Princess Azula and her allies, Mai and Ty Lee, disguised themselves as Kyoshi Warriors in order to enter Ba Sing Se as the Earth King's honored guests. Azula allowed her and her allies' identities to be uncovered by the Dai Li, who forcefully took her to speak with Long Feng. The two allied with each other in order to stage a coup against the Earth King and the Council of Five. Azula then took command of the Dai Li and coordinated the simultaneous capture of the Earth King and the Council of Five, gaining control over the city. Long Feng was in turn released from his prison cell. He attempted to double-cross Azula, but without the support of the Dai Li, he failed and submitted. By the following summer, the city was firmly controlled by Fire Nation forces, who gained access to the city as the Dai Li tore down large sections of the Outer and Inner Walls. The citizens could only look on in horror as the Fire Nation Army flooded into the city.
