Hangul was created under King Sejong the Great in the 1440s as a practical writing system to help common people read and write. The project began around 1443, and the script was officially promulgated to the public in the mid-1440s, with the Hunminjeongeum document issued and Hangul adopted in that period. That timeline—development under Sejong in the 1440s—fits the spirit of the statement, which is why it’s treated as true in this context. For precision, many sources list the formal promulgation as occurring a couple of years after the creation, around 1446, but the essential fact is Sejong’s leadership and the introduction of Hangul during the 1440s.
