Nakdong RiverThe Nakdonggang River or Nakdonggang (nakt͈oŋgaŋ) is the longest river in South Korea, and passes through major cities such as Daegu and Busan. It takes its name from its role as the eastern border of the Gaya confederacy during Korea's Three Kingdoms Era.

The river originates from the junction of the Cheolamcheon and Hwangjicheon streams in Dongjeom-dong, Taebaek city, Gangwon province.
East AsiaEast Asia is the easternmost region of Asia, which is defined in both geographical and ethno-cultural terms. The modern states of East Asia include China, Japan, Mongolia, North Korea, South Korea, and Taiwan. Hong Kong and Macau, two small coastal quasi-dependent territories located in the south of China, are officially highly autonomous but are under Chinese sovereignty.

Yamato periodThe Yamato period is the period of Japanese history when the Imperial court ruled from modern-day Nara Prefecture, then known as Yamato Province. While conventionally assigned to the period 250–710, including both the Kofun period (250–538) and the Asuka period (538–710), the actual start of Yamato rule is disputed. The Yamato court's supremacy was challenged during the Kofun period by other polities centered in various parts of Japan. What is certain is that Yamato clans had major advantages over their neighbouring clans in the 6th century.
Gaya confederacyGaya (, ka.ja) was a Korean confederacy of territorial polities in the Nakdong River basin of southern Korea, growing out of the Byeonhan confederacy of the Samhan period. The traditional period used by historians for Gaya chronology is AD 42–532. According to archaeological evidence in the third and fourth centuries some of the city-states of Byeonhan evolved into the Gaya confederacy, which was later annexed by Silla, one of the Three Kingdoms of Korea. The individual polities that made up the Gaya confederacy have been characterized as small city-states.
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.

Kofun periodThe Kofun period is an era in the history of Japan from about 300 to 538 AD (the date of the introduction of Buddhism), following the Yayoi period. The Kofun and the subsequent Asuka periods are sometimes collectively called the Yamato period. This period is the earliest era of recorded history in Japan, but studies depend heavily on archaeology since the chronology of historical sources tends to be distorted. The word kofun is Japanese for the type of burial mound dating from this era. It was a period of cultural import.
SillaSilla (; ɕiɭ.ɭa; Old Korean: 徐羅伐 Syerapel, 斯羅火 Sïrapïr; RR: Seorabeol; IPA: shʌ̹ɾa̠bʌ̹ɭ), alternatively Shilla, was a Korean kingdom that existed between 57 BCE – 935 CE and located on the southern and central parts of the Korean Peninsula.
