  In 1407, for military purposes, the administrative districts were reorganized, with Gyeongsang-do being divided into Gyeongsangjwa-do (or Gyeongsangjwa Province; left) and Gyeongsangwu-do (or Gyeongsangwu Province; right) as the reference points of the Nakdonggang River.
  
  Before 1895, the area corresponding to modern-day South Gyeongsang Province was part of Gyeongsang Province, one of the Eight Provinces of Korea during the Joseon dynastic kingdom. In 1895, southern Gyeongsang was replaced by the districts of Jinju in the west and Dongnae (modern-day Busan) in the east. In 1896, they were merged to form South Gyeongsang Province.
