During the Proto-Three Kingdoms period, Jeolla region was the center of the Mahan confederacy among Samhan. There were 15 tribal countries out of 54 in the region. During the period of the Three States, this region came to belong to Baekje when it absorbed Mahan. Baekje was destroyed by the Silla and Chinese Tang dynasty allied force in 660 (20th year of King Uija) and ruled by Tang. It became a part of Silla when Tang was expelled in 676 (16th year of King Munmu).

When there were nine states and five small capitals in Unified Silla in 685, there were Wansan-ju (present Jeonju) and Namwon-gyeong (present Namwon) in Jeollabuk-do in existence.

In 892, when General Gyeon Hwon founded Hubaekje (later Baekje), this area was the center of the country for about 50 years. In 936, during the rule of Singeom, it was attributed to Goryeo Dynasty. From 900 to the time when Hubaekje was attributed to Goryeo, Wansan-ju (present Jeonju) had been its capital, and the country ruled the whole Jeolla-do region.

In 996 (14th year of King Seongjong), this region was named Gangnam province and the Korean government established the four states (Jeonju-Jeonju, Yeongju-Gobu, Sunju-Sunchang, and Maju-Okgu) in the North Jeolla region.

Gangnam-do (Jeonbuk) and Haenam-do (Jeonnam) were combined and titled as Jeolla-do in 1018 (9th year of King Hyeonjong's reign).

During the Joseon Dynasty, as the administrative districts of the whole nation were organized in the Eight Provinces system in 1413 (13th year of King Taejong's reign), Jeolla-do took charge of vast areas of one prefecture, four autonomous counties, four protectorates, 12 counties, and 31 counties covering present Jeollanam-do, Jeollabuk-do and Jeju-do.

In 1896 (33rd year of King Gojong's reign), the whole country was divided into 13 provinces. Jeolla-do was divided into Jeollanam-do and Jeollabuk-do. Jeollabuk-do consisted of 26 counties.During the Japanese colonial periodn, the province became the province of Zenrahoku-dō, which was reverted into the original subdivision in 1945.

In 1963, Geumsan-gun was incorporated into Chungnam, and Wido-myeon of Jeonnam was incorporated into Jeonbuk. Jeongju-eup and Namwon-eup were raised to cities in 1981 and Gimje-eup was raised to city status in 1989. Wansan-gu and Deokjin-gu were established in Jeonju-city in the same year.

Due to establishment of cities in the mixed type of city-farming area in 1995, Okgu, Jeungeup, Namwon, Gimje and Iksan-Guns were combined. Gimje and Iksan-guns were merged and Gunsan, Jeonju, Namwon, Gimje and Iri cities were integrated. Through repeated reorganizations of administrative districts, now the region consists of the administrative districts of six cities and eight counties.

Failures in the hosting of the 25th World Scout Jamboree in July 2023 led to political controversy, adding to long-term concerns about a lack of development alongside population decline and aging. As a result of a law passed in December 2023, on 18 January 2024 the North Jeolla became a special self-governing province and was renamed Jeonbuk State (Jeonbuk being an abbreviation of North Jeolla). This new status increases the autonomy of the province's government, being able to approve projects requiring environmental impact assessments and tailor its own immigration and tourism policies.[1]
