Lee Seong-gye (October 27, 1335 (October 11, 1335) to June 18, 1408 (May 24, 1408) was the first king to be a shaman, politician, and founder of Joseon.

Lee Seong-gye became famous for his distinguished military service in the war against Japanese pirates and the Red Turban Invasion of Korea at the end of the Goryeo Dynasty. The Yuihwado Rebellion eliminated King Wu and Choe Yeong and took political and military power in one hand.

In conjunction with emerging political forces, the new Dynasty 'Joseon' was founded to replace Goryeo. He was reigned for seven years from 1392 to 1398, and was succeeded by King Jeongjong, the second king, in the wake of the prince's rebellion.

The Tripitaka Koreana Tripitaka Correana, or the Tripitaka Koreana in Hapcheon, South Gyeongsang Province, began its first edition in 1236 (the 23rd year of King Gojong's reign) in Ganghwa County, Korea, in order to prevent the invasion of Mongolia by force in Haeinsa Temple, Hapcheon County, South Gyeongsang Province.

On December 20, 1962, it was designated as the 32nd National Treasure of the Republic of Korea, and changed to the current name on August 25, 2010.

The Tripitaka Koreana, which is considered to be the oldest of the existing world's great wonders and the most complete of its stay and contents, was designated as a World Heritage Site in 2007.

Goryeo porcelain was a pottery made during the Goryeo Dynasty, which refers to celadon made during the Goryeo Dynasty, such as celadon, white porcelain, black yuja, and iron yuja, but has generally been recognized as a reference to Goryeo celadon.

Goryeo celadon was developed under the influence of pottery from the Song Dynasty and its techniques were much better than those of the Song Dynasty, so the Song Dynasty people praised it as the best in the world.

The excellence of Goryeo celadon can be attributed to its beautiful color. Some are yellowish or yellowish brown, but others are especially beautiful.

There is National Treasure No. 115 of the celadon Sanggamdang First Gate Wan, which represents the period.

Bulguksa Temple is a temple belonging to the Jogye Order of Korean Buddhism on Mount Toham in the east of Gyeongju, North Gyeongsang Province. It was reconstructed on a large scale during the reign of King Gyeongdeok of Silla and King Hyegong of Silla.

Since the Silla Dynasty, it has been contracted several times from Goryeo to the Joseon Dynasty, and was burned down during the Japanese Invasion of Korea in 1592. It is the headquarters of the 11th Diocese of the Jogye Order of Korean Buddhism and was designated as a UNESCO World Heritage Site in 1995.

Joseon Baekja is the most widely known pottery in Korea, along with Goryeo Cheongja(celadon porcelain).

Baekja(White porcelain) and Buncheongsagi(powdered blueware) are representative ceramics of Korea. Baekja was continuously produced and used throughout the Joseon Dynasty, while Buncheongsagi were produced for 150 years.

The white porcelain, which shows the beauty of purity and moderation, was used by new Dynasty and the noblity who pursued Confucian philosophy, so it contains their thoughts and preferences.

The Baekja of National Treasure No. 258 is considered one of the most representative white porcelain bottles of the time in a state in which the bold and tasteful pictures of bamboo show the spirit of the Sunbi people at that time.

Taejo (r. 918-943 CE), previously known as Wang Geon or Wang Kon, was the founder and first king of the Goryeo (Koryo) kingdom which unified and ruled ancient Korea from 918 CE to 1392 CE. Wang Geon was given the posthumous title of Taejo meaning 'Great Founder.' His Dynasty would oversee an unprecedented flourishing of Korean culture, and its name is the origin of modern Korea's English name.

The Fall of Silla
The Unified Silla Kingdom (668- 935 CE) had held sway over the Korean peninsula for three centuries, but the state was in a slow decline. Rebellions from the peasantry and the aristocracy were rife, and there followed a period of political turmoil referred to as the Later Three Kingdoms period (889-935). Gyeon Hwon, a peasant leader, took advantage of the political unrest in 892 CE and formed a revival of the old Baekje kingdom in the south-west portion of the peninsula. Meanwhile, an aristocratic Buddhist monk leader, Gung Ye declared a new Goguryeo state in the north in 901 CE, known as Later Goguryeo. Gung Ye was assisted by his first minister and general Wang Geon, the son of a wealthy merchant and local headman at Gaeseong in the Silla kingdom.

Jeong Do-jeon (1342~1398) was a civil official, politician, Confucian scholar, and revolutionary during the late Goryeo and early Joseon Periods.

At the end of the Goryeo Dynasty, he criticized the corrupt politics of the Gwon Mun-se people and the Buddhism that was parasitic on them, and made a key contribution to the establishment of the Joseon Dynasty, a centralized bureaucracy based on Neo-Confucianism.

As the first meritorious retainer and supreme power of the Joseon Dynasty, he laid the foundation for the 500th anniversary of the Joseon Dynasty by laying the foundation for the ideological foundation of the Joseon Dynasty, and named the buildings and streets of downtown Hanyang by himself.

Jeong Do-jeon, a revolutionary comrade of Yi Seong-gye, was killed by Bang Won (the third king of Joseon), the fifth son of Yi Seong-gye.
