History
Pre-First Scinfaxi War
Known human habitation of the what the Korean peninsula on Earth dated back to 40,000 BCE. The kingdom of Gojoseon fell to the Chinese Han dynasty in 108 BCE. It was followed by the Three Kingdoms period, in which Korea was divided into Goguryeo, Baekje, and Silla. In 668 CE, Silla conquered Baekje and Goguryeo with the aid of the Chinese Tang dynasty, forming Unified Silla. In the late 9th century, Unified Silla collapsed into three states, beginning the Later Three Kingdoms period. In 918, Goguryeo was resurrected as Goryeo, which achieved what has been called a "true national unification" by Korean historians. Goryeo, whose name developed into the modern exonym "Korea", saw the invention of the first metal movable type. During the 13th century, Goryeo became a vassal state of the Mongol Empire. Goryeo overthrew Mongol rule, establishing the Joseon dynasty in 1392.
In 1895, China lost suzerainty over Korea to Japan in the First Sino-Japanese War. In 1897, Joseon was replaced by the Korean Empire. Japan's victory in the 1904–1905 Russo-Japanese War expelled Russian influence in Korea and Manchuria. In 1905, the Korean Empire became a protectorate of the Empire of Japan. In 1910, the Empire of Japan officially annexed the Korean peninsula. Korea under Japanese rule was marked by industrialization and modernization, economic exploitation, and brutal suppression of the Korean independence movement.
