The history of Korea begins with the founding of Joseon (also known as "Gojoseon", or Old Joseon, to differentiate it with the 14th century dynasty) in 2333 BC by Dangun, according to Korea's foundation mythology.
Gojoseon expanded until it controlled the northern Korean Peninsula and parts of Manchuria.
Thus, its force was diminished and it only served as a trade center until it was conquered by Goguryeo in 313.
During the period known as the Proto–Three Kingdoms of Korea, the states of Buyeo, Okjeo, Dongye, and Samhan occupied the Korean peninsula and southern Manchuria.
in the Goryeo–Khitan War, Goryeo experienced a golden age that lasted a century, during which the Tripitaka Koreana was completed and there were great developments in printing and publishing, promoting learning and dispersing knowledge on philosophy, literature, religion, and science; by 1100, there were 12 universities that produced famous scholars and scientists.
However, the Mongol invasions in the 13th century greatly weakened the kingdom.
The name Daehan, which means "great Han" literally, derives from Samhan (Three Hans).
However, the name Joseon was still widely used by Koreans to refer to their country, though it was no longer the official name.
After Goryeo was replaced by Joseon in 1392, Joseon became the official name for the entire territory, though it was not universally accepted.Its rich and vibrant culture left 19 UNESCO Intangible Cultural Heritages of Humanity, the third largest in the world, along with 12 World Heritage Sites.Annexed into Imperial Japan in 1910, the country's current political structure dates back to 1919 when the Korean Provisional Government was organized in Shanghai, China as a government in exile and then moved to Chungking to resist the Japanese occupation of Korea.Relationships between Korea and China remained relatively peaceful during this time.Later Silla carried on the maritime prowess of Baekje, which acted like the Phoenicia of medieval East Asia, and during the 8th and 9th centuries dominated the seas of East Asia and the trade between China, Korea and Japan, most notably during the time of Jang Bogo; in addition, Silla people made overseas communities in China on the Shandong Peninsula and the mouth of the Yangtze River.
