Korea (No China)

Korea is a naion in East Asia. It is bordered by the Soviet Union to the north and Mongolia to the west. Its capital and largest city is Pyongyang. Other notable cities might include Hanseong, Busan or Harbin. The name "Korea" is derived from "Goryeo", a name of the dynasty which ruled the country in the Middle Ages. Marco Polo came across the country at that time and translated "Goryeo" to his native language as "Cauli"; which got converted to "Korea" in English.

Gojoseon and Jin State
Gojoseon was the first Korean kingdom, located in the north of the peninsula and Manchuria, later alongside the state of Jin in the south of the peninsula.

Goguryeo
Goguryeo was founded in 37 BC by Jumong (posthumously titled as Dongmyeongseong, a royal given title). Later, King Taejo centralized the government. Goguryeo was the first Korean kingdom to adopt Buddhism as the state religion in 372, in King Sosurim's reign. Goguryeo (also spelled as Koguryŏ) was also known as Goryeo (also spelled as Koryŏ), and it eventually became the source of the modern name of Korea. Goguryeo reached its zenith in the 5th century, becoming a powerful empire and one of the great powers in East Asia, when Gwanggaeto the Great and his son, Jangsu, expanded the country into almost all of Manchuria, parts of Mongolia, parts of Russia, and took the present-day city of Seoul from Baekje.

Goryeo
Goryeo was founded by Wang Geon in 918 and became the ruling dynasty of Korea by 936. It was named "Goryeo" because Wang Geon, a descendant of Goguryeo nobility, deemed the nation as the successor of Goguryeo.
