The history of Ulsan is rooted in deep antiquity, back when the first state formations were flourishing on the Korean Peninsula. Being a strategically important port in the south-east, the city has played a key role in maritime trade and the country's defence for centuries.
Foundation and First Mentions
The first settlements in the territory of modern Ulsan existed as early as the prehistoric era, as evidenced by numerous archaeological finds, including the famous Bangudae Petroglyphs. During the Three Kingdoms period (1st–7th centuries AD), this area was part of the Jinhan confederacy, and later became an important port in the Kingdom of Silla. It was during the Unified Silla era that Ulsan transformed into one of the main trading hubs, through which active maritime trade was conducted with China, Japan, and even countries in Central Asia. The name of the city, according to one theory, comes from characters meaning "fortress" and "mountain", which can be interpreted as a "place surrounded by a fortress of mountains".
Key Factors of Formation and Development
Throughout its history, Ulsan's development has been inextricably linked to its geographical position. The key factors were:
- Advantageous Coastal Location: Situated at the mouth of the Taehwagang River flowing into the Sea of Japan, the city initially developed as a centre for fishing and maritime trade. In the past, it was also known as the centre of whaling in South Korea.
- Trading Port: As early as the Silla period, Ulsan was one of the main ports receiving goods via the Silk Road and maritime routes. This role was preserved in subsequent eras.
- Industrial Centre: Radical changes occurred in 1962 when Ulsan was designated as the country's first special industrial zone. This marked the beginning of its transformation into the "Industrial Capital of the Republic of Korea", where shipbuilding, automotive, and petrochemical industries are concentrated.
Early Cultural and Economic Features
Before the industrial boom of the 20th century, Ulsan was predominantly an agricultural and trading centre, as well as a major fishing port. Its cultural heritage is rich with monuments from the Silla period. Historically, the city was known for whaling, which is reflected today in the annual Whale Festival and a thematic museum. The strategic importance of the port made it a vital economic asset, ensuring trade connections and the prosperity of the region for many centuries.
