South Korea Profile

History of South Korea

South Korea’s history spans thousands of years, rooted in the early Korean kingdoms of Goguryeo, Baekje, and Silla, which have shaped the region’s culture, art, and governance. The Silla Kingdom unified much of the peninsula in the 7th century, ushering in a golden age of Buddhism, architecture, and literature.

In the late 14th century, the Joseon Dynasty rose to power, establishing Confucianism as the foundation of Korean society and creating the Korean alphabet, Hangul, under the leadership of King Sejong the Great. This dynasty lasted over five centuries, leaving a lasting mark on Korea’s culture and traditions.

Following Japanese annexation in 1910, Korea endured decades of colonial rule until the end of World War II, when the peninsula was divided along the 38th parallel. In 1948, the Republic of Korea (South Korea) was established, while the Democratic People’s Republic of Korea (North Korea) was formed in the north.

The Korean War (1950-1953) devastated the country but ended in an armistice, leaving the peninsula technically still at war. Despite these challenges, South Korea rapidly industrialized and modernized in the latter half of the 20th century, transforming from a war-torn nation into one of the world’s leading economies.

Today, it is recognized for its resilience, innovation, and global cultural influence.

Geography of South Korea

Located in East Asia, South Korea occupies the southern portion of the Korean Peninsula, covering about 100,210 square kilometers (38,690 square miles). The country shares a land border with North Korea to the north, while its coastline borders the Yellow Sea to the west, the Korea Strait to the south, and the Sea of Japan (East Sea) to the east.

South Korea’s landscape is predominantly mountainous, with the Taebaek Mountains running along the eastern coast and lower hills and plains extending westward. The highest peak, Hallasan (1,947 meters or 6,388 feet), is a dormant volcano located on Jeju Island, a UNESCO World Heritage Site known for its unique ecology and scenic beauty.

The Han River flows through Seoul, providing a vital water source and shaping the capital’s geography, while the Nakdong River, the country’s longest, winds through the southeastern region. The west and south coasts feature numerous islands and inlets, contributing to rich marine ecosystems and a thriving fishing industry.

South Korea experiences a temperate climate with four distinct seasons. Winters (December–February) are cold and dry, especially in the northern and inland areas, while summers (June–August) are hot and humid, influenced by the East Asian monsoon. Spring and autumn are mild and short, often considered the most pleasant times of the year.
