The history of Korea is a long and complex narrative. It began with ancient eras and the legendary Three Kingdoms, eventually leading to periods of unified dynasties. One of the nation's most significant historical achievements was the development of movable type. The Goryeo dynasty created the world's first metal-based movable type in 1234, a precursor to the Jikji, the oldest surviving metal movable type book printed in 1377.

: The oldest surviving metal movable type book, the Jikji, was printed in 1377, and Goryeo created the world's first metal-based movable type in 1234.[46]

The modern era brought significant challenges, including the Japanese occupation and the subsequent division of the peninsula. The struggle for independence was marked by pivotal moments such as the March First Movement in 1919, where protests erupted in Seoul against colonial rule.

Following the end of World War II and the establishment of the ROK (Republic of Korea) on August 15, 1948, the nation faced the devastation of the Korean War. However, from these ashes, the country underwent an unprecedented economic transformation known as the Miracle on the Han River. Between 1962 and 1994, the economy grew at an average of 10% annually, driven by a 20% annual growth in exports.
