South Jeolla Province: A Legacy of History, Agriculture, and Industry
Located in the Honam region, South Jeolla Province (known in Korean as Jeollanam-do) has long served as a vital cultural and economic pillar of the Korean peninsula. As the southernmost province on the mainland, it is characterized by a stunning coastline, fertile plains, and a rich historical tapestry that stretches back to the ancient Samhan period. While the administrative landscape changed on July 1, 2026, when the province merged with Gwangju to form the new special metropolitan city of Jeonnam-Gwangju, the identity and heritage of the South Jeolla region remain deeply significant.

Historical Evolution
The history of this region is a journey through Korea's most defining eras. During the Proto Three Kingdoms period, the area was part of Mahan. As the Three Kingdoms period progressed, it became part of the Baekje kingdom, specifically within the Gujihakseong region centered at Mujinju.
Under the Unified Silla period, the administrative center was known as Muju, overseeing dozens of counties and prefectures. The Goryeo dynasty saw significant reorganization; by the 9th year of King Hyeonjong's reign, the name Jeollado was officially adopted after merging Haeyangdo with Gangnamdo.
During the Joseon dynasty, the region was a core part of the Eight Provinces system. While various names like Gwangnamdo were used, Jeollado remained the predominant designation. The modern structure of South Jeolla began to take shape in 1896 when the province was split into northern and southern regions, establishing the Jeollanam-do we recognize today.
Geography and Environment
South Jeolla is defined by its diverse landscape. To the west lies the Yellow Sea, while the south is bounded by the Jeju Strait. The region boasts a massive coastline of approximately 6,100 kilometers, dotted with nearly 2,000 islands—though about three-quarters of these are uninhabited.
The climate is among the warmest on the Korean peninsula, which, combined with abundant rainfall and fertile plains along the Seomjin, Yeongsan, and Tamjin rivers, makes the area an agricultural powerhouse. The province is a leading producer of rice, wheat, barley, pulses, potatoes, and various vegetables. Additionally, its coastal waters are famous for seaweed and oyster cultivation.
Beyond agriculture, the environment is remarkably clean, with heavy metal levels reported at only one-thirtieth of the required environmental standards. While gold and coal are mined in small amounts, the region's focus has shifted toward heavy industry and high-tech infrastructure.
Economic Powerhouses and Future Growth
The economy of South Jeolla is anchored by massive industrial complexes. The Yeosu National Industrial Complex stands as the nation's largest petrochemical hub, while the city of Gwangyang hosts the Gwangyang Steel Mill, one of the world's largest single steel producers with an annual capacity of 21 million tons.
Looking toward the future, the region is pivoting toward the digital economy. In February 2025, South Korea announced plans for a massive $35 billion artificial intelligence (AI) data center project. This facility is expected to have a 3GW capacity, supported by agreements to ensure stable access to essential energy and water resources.
