The History of Korea presents a chronological account of Korea from ancient days, over 2000 B. C, to modern 20th century Korea. Hulbert said that Korea and Japan have the same two racial types, but Japan is mostly Malay and Korea is mostly Manchu-Korean. He claimed that Korea is physically mostly of the northern type, but also said that the nation, being physically mostly of the northern type, did not disprove Hulbert's claim that the Malay element developed Korea's first civilization, although not necessarily originating Korea's first civilization, and the Malay element imposed its language in its main features in the entire peninsula.
