Korea
Hangul Day (also spelled as Hangeul Day) is a day that celebrates the creation of the Hunminjeongeum (Hangul, Korean alphabet), which was inscribed to the UNESCO Memory of the World Register in 1997. Hangul was created by Sejong the Great in 1443 and proclaimed in 1446. 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. Hangul Day was founded in 1926 during the Japanese occupation by members of the Korean Language Society, whose goal was to preserve the Korean language during a time of rapid forced Japanization. Today, both South Korea and North Korea celebrate Hangul Day as a national holiday.Sources
Memoirs of Lady Hyegyeong
By the time Lady Hyegyong had begun writing in the late 1700s, the invention of hangul had already become the voice of female narratives, which began to appear and allowed female narratives to become more and more plentiful. Haboush determines this increase to be correlated with the decrease of yangban women's inheritance rights. As family structures began to change, women turned to the pen “to bear public witness to history” and express for themselves how customs and family structures were changing at the time. Similarly, by writing her own autobiographical memoirs, Lady Hyegyong was able to express for herself insights into life at the Joseon Court during an extraordinary time.
