GojoseonGojoseon ( ko.dʑo.sʌn), also called Joseon ( tɕo.sʌn), was the first kingdom on the Korean Peninsula. According to Korean mythology, the kingdom was established by the legendary founder named Dangun. Gojoseon possessed the most advanced culture in the Korean Peninsula at the time and was an important marker in the progression towards the more centralized states of later periods. The addition of Go (고, ), meaning "ancient", is used in historiography to distinguish the kingdom from the Joseon dynasty founded in 1392 CE.
BusanBusan (pusan; ), officially known as Busan Metropolitan City, is South Korea's second most populous city after Seoul, with a population of over 3.4 million inhabitants as of 2017. Formerly romanized as Pusan (and Fusan before that), it is the economic, cultural and educational center of southeastern South Korea, with its port being South Korea's busiest and the sixth-busiest in the world. The surrounding "Southeastern Maritime Industrial Region" (including Ulsan, South Gyeongsang, Daegu, and some of North Gyeongsang and South Jeolla) is South Korea's largest industrial area.
Sea of JapanThe Sea of Japan is the marginal sea between the Japanese archipelago, Sakhalin, the Korean Peninsula, and the mainland of the Russian Far East. The Japanese archipelago separates the sea from the Pacific Ocean. Like the Mediterranean Sea, it has almost no tides due to its nearly complete enclosure from the Pacific Ocean. This isolation also affects faunal diversity and salinity, both of which are lower than in the open ocean. The sea has no large islands, bays or capes.
BaekjeBaekje or Paekche (, pɛk̚.t͈ɕe) was a Korean kingdom located in southwestern Korea from 18 BC to 660 AD. It was one of the Three Kingdoms of Korea, together with Goguryeo and Silla. While the three kingdoms were in separate existence, Baekje had the highest population of approximately 3,800,000 people (760,000 households), which was similar to that of Goguryeo (3,500,000 people) and much larger than that of Silla (850,000 people). Baekje was founded by Onjo, the third son of Goguryeo's founder Jumong and Soseono, at Wiryeseong (present-day southern Seoul).
History of KoreaThe Lower Paleolithic era on the Korean Peninsula and in Manchuria began roughly half a million years ago. The earliest known Korean pottery dates to around 8000 BC, and the Neolithic period began after 6000 BC, followed by the Bronze Age by 2000 BC, and the Iron Age around 700 BC. Similarly, according to The History of Korea, the Paleolithic people are not the direct ancestors of the present Korean people, but their direct ancestors are estimated to be the Neolithic People of about 2000 BC.
