There is evidence of occupation through hunter-gatherer and burial sites from this period, such as at Tongsamdong (in southeastern Korea near present day Pusan), along with pottery, stone agricultural tools, and cereal cultivation of millet. D., Korea has been developing as a distinct people for 5,000-6,000 years. Distinct Korean style tools first began appearing in “Wae” (Japan), when Korean weapons (Dagger culture) emerged. Chariot fittings have been found near Pyongyang and the Taedong River basin (that flows from northeast to southeast through Pyongyang). After the schism in the Buddhist religion in northeast India in the first century A. the Chinese colony of Lolang was established near Pyongyang. Iron was exported from the lower Naktong River in southeastern Korea to Wae (Japan) and Lolang. Cultural elements from China, northern nomadic tribes, Lolang, and the Buddhist religion were incorporated during this period of Koguryo dominance.The spread of rice farming reached northern areas of the Peninsula by 1500 B. Iron Age culture became widespread in southern Korea by the second century B. Confucianism, a learning and social philosophy rooted in a series of particular relationships among and between family, friends, and rulers, became prominent from the third century B. D., the Mahayana Buddhism that offered universal salvation (versus the more conservative Theravada Buddhism) arrived in China and Korea where it began to be shared with Confucianism and Daoism. C., Korea (except in the southeast area around present day Pusan) came under the domination of the Chinese Han empire. The Kingdom of Koguryo established the first native Korean state near the Yalu River (separating present day China from northern Korea) in the north in 37 B. by the Maek Tribe, even while still in the Han empire. Iron technology in this period became stronger and sharper as it was incorporated into weapons and agricultural tools.A peninsula 600 miles long, north-south, with an average width of 150 miles, it is separated from China by as little as 130 miles on the west by the Yellow Sea (and Korean Bay, a northern section of the Yellow Sea) while sharing a 500 mile northern boundary with China marked by the great Yalu River.It also shares an 11 mile northeast boundary with Russia marked by the Tumen River.Traces of the earliest ancestors of modern humans have been discovered in tropical eastern sub-Sahara Africa as early as 5 million years ago. Koguryo expanded its territory well into eastern Manchuria (present day northeast China) in the north, as far south near the Han River (flows through present day Seoul) in proximity of where the other two major kingdoms emerged, Paekche (c. D.) in the in the southwestern portion of the Peninsula, and the more powerful Silla (c. D.) in the southeastern portion in and around the Naktong River valley.
And since there were no Eurocentric or New World societies until after the Conquest of the original Indigenous societies that occurred from the late 1400s through the 1700s, the longest period of organized society we in the West possess is no more than 500 years old.
The Yi dynasty created a new capital at Seoul, established Confucianism as the official religion, and developed a Korean phoenetical alphabet.
Japanese warrior Toyotomi Hideyoshi won control of most of geographically close-by Japan in 1590, and two years later invaded Korea with 160,000 men seeking to conquer China after subduing Korea.
In 1231 Mongol forces invaded from China and eventually the Koryo kings accepted Mongol rule.
In 1392, Yi Songgye, with the aid of the Ming dynasty (which had replaced the Mongols in China), seized power.
