supports: Manchuria is a modern name, first created by Japanese, given to a large geographic region in Northeast Asia. Depending on the context, Manchuria can either refer to a region that falls entirely within the People's Republic of China, or a larger region divided between China and Russia. The region that falls entirely within modern China is now usually referred to as Northeast China in China, although "Manchuria" is widely used outside of China to denote the geographical and historical region. This region is the traditional homeland of the Xianbei, Khitan, and Jurchen (later called Manchu) peoples, who built several states historically, although no term for "Manchuria" exists in the Manchu language, which originally referred to the area as the "Three Eastern Provinces". The Korean Peninsula is a peninsula in East Asia. It extends southwards for about from continental Asia into the Pacific Ocean and is surrounded by the Sea of Japan (East Sea) to the east, and the Yellow Sea (West Sea) to the west, the Korea Strait connecting the first two bodies of water. Baekje or Paekche (18 BC  660 AD) was a kingdom located in southwest Korea. It was one of the Three Kingdoms of Korea, together with Goguryeo and Silla. Korea is a historical state in East Asia, since 1945 divided into two distinct sovereign states: North Korea (officially the "Democratic People's Republic of Korea") and South Korea (officially the "Republic of Korea"). Located on the Korean Peninsula, Korea is bordered by China to the northwest and Russia to the northeast. It is separated from Japan to the east by the Korea Strait and the East Sea. Goguryeo (, 37 BCE668 CE) or Goryeo, was one of the ancient Three Kingdoms of Korea, located in the northern and central parts of the Korean Peninsula and the southern and central parts of inner and outer Manchuria. Goguryeo was an active participant in the power struggle for control of the Korean peninsula and was also associated with the foreign affairs of neighboring polities in China and Japan. Goryeo, also spelled as Kory (9181392), was a Korean dynasty established in 918 by King Taejo. This kingdom later gave name to the modern exonym "Korea". It united the Later Three Kingdoms in 936 and ruled most of the Korean Peninsula until it was removed by the founder of the Joseon in 1392. Goryeo expanded Korea's borders to present-day Wonsan in the northeast (936943), the Yalu River (993) and finally almost the whole of the Korean Peninsula (1374). King Jungcheon of Goguryeo ( 224 -- 270 , r. 248 -- 270 ) was the 12th ruler of Goguryeo , the northernmost of the Three Kingdoms of Korea . The concept of the Three Kingdoms of Korea refers to the three kingdoms of Baekje (), Silla () and Goguryeo (), which was later known as Goryeo (), from which the name "Korea" is derived. The Three Kingdoms period was defined as being from 57 BC to 668 AD (but there existed about 78 tribal states in the southern region of Korean peninsula and relatively big states like Okjeo, Buyeo, and Dongye in its northern part and Manchuria). China, officially the People's Republic of China (PRC), is a unitary sovereign state in East Asia. With a population of over 1.381 billion, it is the world's most populous country. The state is governed by the Communist Party of China, and its capital is Beijing. It exercises jurisdiction over 22 provinces, five autonomous regions, four direct-controlled municipalities (Beijing, Tianjin, Shanghai, and Chongqing), and two mostly self-governing special administrative regions (Hong Kong and Macau), and claims sovereignty over Taiwan. The country's major urban areas include Shanghai, Guangzhou, Beijing, Chongqing, Shenzhen, Tianjin and Hong Kong. China is a great power and a major regional power within Asia, and has been characterized as a potential superpower. Dongye, which means the Eastern Ye, was a Korean chiefdom which occupied portions of the northeastern Korean peninsula from roughly 3rd-century BC to around early 5th-century. It bordered Goguryeo and Okjeo to the north, Jinhan to the south, and China's Lelang Commandery to the west. Today, this territory consists of the provinces of South Hamgyng and Kangwon in North Korea, and Gangwon in South Korea. It is believed to be one of the ancient tribes that were formed into the Tungusic peoples. The Three Kingdoms (AD 220280) was the tripartite division of China between the states of Wei, Shu, and Wu, following the Han dynasty and preceding the Jin dynasty. The term "Three Kingdoms" itself is something of a mistranslation, since each state was eventually headed not by a king, but by an emperor who claimed legitimate succession from the Han dynasty. Nevertheless, the term "Three Kingdoms" has become standard among sinologists. To further distinguish the three states from other historical Chinese states of similar names, historians have added a relevant character: Wei is also known as Cao Wei, Shu is also known as Shu Han, and Wu is also known as Dong (or Eastern) Wu. Silla (57 BC  935 AD) was one of the Three Kingdoms of Korea, and one of the world's longest sustained dynasties. Although it was founded by King Park Hyeokgeose, the dynasty was ruled by the Gyeongju Kim (, ) clan for most of its 992-year history. It began as a chiefdom in the Samhan confederacies, once allied with China, but Silla eventually conquered the other two kingdoms, Baekje in 660 and Goguryeo in 668. Thereafter, Unified Silla or Later Silla, as it is often referred to, occupied most of the Korean Peninsula, while the northern part re-emerged as Balhae, a successor-state of Goguryeo. After nearly 1000 years of rule, Silla fragmented into the brief Later Three Kingdoms, Silla, Hubaekje, and Taebong, handing over power to its successor dynasty Goryeo in 935.
