The Southern Water Tribe was as equally advanced as their sister tribe prior to the Hundred Year War. However, continuous raids by the Fire Nation severely damaged the tribe, and eventually resulted in the loss of all waterbenders, apart from Katara. Without waterbenders, the development of infrastructure was nearly impossible. On top of that, the Tribal Chief left in order to aid the Earth Kingdom, causing the lack of a true authority figure to govern the tribe. This resulted in the dispersion of the tribe into various villages.
