Jeolla Province

Baekje in 576.

During the Samhan era of Korean history, the area of Jeolla was controlled by the Mahan confederacy and the Tamna kingdom on Jeju. Fifteen of the 45 Korean tribes had their bases in this region. When Baekje overtook Mahan by the 5th century, the Three Kingdoms era began and the region became part of southern Baekje. Jungbang was the center of the province during this period.

When Silla conquered Baekje with the help of Tang China in 660, it became a territory of Later Silla during the 16th year of the reign of Munmu of Silla. Silla reorganized this territory into nine ju (주) and five gyeong (경), three of the ju belonging to the former Baekje. The northern territory of former Baekje, Ung (Ungju; Hanja: 熊州), corresponds to modern-day South Chungcheong Province.

The middle area consisted of Wansan (Hanja: 完山州) and Namwon, which correspond to modern-day North Jeolla. Wansan was later renamed Jeonju. The southern area consisted of Mujin (Mujin-ju), which was renamed Mu (Hanja: 武州) in 757, the 16th year of the reign of Gyeongdeok of Silla. Mu consisted of one gun and 43 hyeon, and corresponds to modern-day South Jeolla.

In 983, during the second year of the reign of Seongjong of Goryeo, the country was reorganized into 12 mok. Jeonju became Jeonju-mok (Hanja: 全州牧), while Muju was split into the two mok of Naju and Seungju. In 995, King Seongjong again reorganized the country, this time into 10 do (Korean: 도; Hanja: 道; lit. province). Jeonju-mok was renamed Gangnam-do (lit. 'province south of the river') while Naju and Seungju were reunited and renamed Haeyang-do (lit. 'ocean province').

In 1018, during the 9th year of the reign of Hyeonjong of Goryeo, the country was again reorganized into 5 do, and the provinces of Gangnam and Haeyang were merged to form the province of Jeollaju (Hanja: 全羅州道). The name derived from the names of the principal cities of Jeonju (Hanja: 全州) and Naju (Hanja: 羅州). (The difference between na- and -la is due to the (initial sound rule of modern Korean). This was the first time the area currently known as Jeolla was united under one administrative division, and it would remain this way for nearly eight centuries.

In 1413, during 13th year of the reign of Taejong of Joseon, the territories were once again reorganized into 8 do. This is the era of the historic Eight Provinces. Jeollaju-do was variously known as Gwangnam, Jeongwang, and Jeonnam, but the original name persisted, and was eventually shortened to simply Jeolla-do (Hanja: 全羅道).

The Donghak Peasant Revolution of 1894–1895 began in Jeolla-do, which was a peasant revolt fueled by the fervor of the believed coming of a local messiah and protests over Seoul's high taxes on rice and the increasing number of Japanese traders in Joseon. There was anti-Japanese sentiment due to the Japanese invasions of Korea (1592–1598).

On May 26, 1895, Gojong of Korea replaced the 8 do system with a 23 bu district system and Jeolla was replaced by the districts of Jeonju (Korean: 전주부; Hanja: 全州府; RR: Jeonjubu) in the northwest, Naju (나주부; 羅州府; Najubu) in the southwest, Namwon (남원부; 南原府; Namwonbu) in the east, and Jeju (제주부; 濟州府; Jejubu) on Jeju-do.

On August 4, 1896, Emperor Gojong issued Royal Order 36, repealing the district system and restoring the province system. Jeolla, like Chungcheong Province, Gyeongsang Province, Hamgyong Province and Pyongan Province, was divided north-south into North Jeolla Province and South Jeolla Province, bringing the total to 13 provinces.

North Jeolla Province consisted of the Jeonju and northern Namwon districts, while South Jeolla Province consisted of the southern Namwon districts, Naju district, and Jeju island. Jeonju was retained as the capital of North Jeolla, with Gwangju being made the capital of South Jeolla. The capital of South Jeolla was later moved to Namak in 2005, and Gwangju was designated a Special City.

Jeolla is a stronghold of the liberal Democratic Party of Korea.
