Shin Chaeho (1880–1936), the founder of the nationalistic historiography of modern Korea and a Korean independence movement activist, published his influential book of reconstructed history "Joseon Sanggosa" ("The Early History of Joseon") in 1924–25, proclaiming that Koreans are descendants of Dangun, the legendary ancestor of Korean people, who merged with Buyo of Manchuria to form the Goguryeo people.
