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.
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.
The Republic of the United States of America, and its Europeon antecedent communities, only go back 400 years.
There is evidence that some of the Indigenous stock in the Western hemisphere originated in portions of Asia, including the Korean Peninsula.
There are no regions in the Western world that possess a million-plus year history of human activity as does the Korean Peninsula.
The arts flourished and Buddhism became the dominant religion.
In 935 the Silla dynasty was overthrown relatively peacefully by the Koryo dynasty at which time literature was cultivated and Confucianism (from China) controlled the pattern of government even though Buddhism remained the state religion. The first Korean histories were published, using movable type, which led to the world’s first casting of metal type in 1403.
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.
By 1.8 millions years ago early hominids (walking bipedal) began spreading out from these original homelands, migrating into temperate regions as distant as East Asia. Many sites have been found of lavishly furnished tombs for the elite in Koguryo society, adorned with exquisite paintings.
It is separated from Japan on the east by the Sea of Japan.
