Hangul Day
Before the creation of Hangul, people in Korea (known as Joseon at the time) primarily wrote using Classical Chinese alongside native phonetic writing systems that predate Hangul by hundreds of years, including idu, hyangchal, gugyeol, and gakpil. However, due to the fundamental differences between the Korean and Chinese languages, and the large number of characters needed to be learned, there was much difficulty in learning how to write using Chinese characters for the lower classes, who often didn't have the privilege of education. To assuage this problem, King Sejong created the unique alphabet known as Hangul to promote literacy among the common people.
Sangoku Tsūran Zusetsu
A copy of "Sangoku Tsūran Zusetsu" was brought to Europe by Isaac Titsingh (1745-1812). In Paris, the text represented the first appearance of Korean han'gŭl in Europe. After Titsingh's death, the printed original and Titsingh's translation were purchased by Jean-Pierre Abel-Rémusat (1788-1832) at the Collège de France. After Rémusat's death, Julius Klaproth (1783-1835) at the "Institut Royal" in Paris published his version of Titsingh's work. In 1832, the Oriental Translation Fund of Great Britain and Ireland supported the posthumous abridged publication of Titsingh's French translation.
