The King Who Invented an Alphabet, and the Scholars Who Tried to Stop Him | King Sejong

In 1444, seven scholars from King Sejong's own academy sent him a protest. His new letters, they wrote, were marvellous — and giving up Chinese characters for them would be like "throwing away the fragrance of storax, to take up a beetle's ball of dung." Those letters became Hangul, the Korean alphabet. This is the story of why a fifteenth-century king invented an alphabet for ordinary people, how its 28 letters were designed (consonants shaped like the organs of speech, vowels from heaven, earth and human), who fought it, and how it survived — told only from the records of his court: the Annals of the Joseon Dynasty and the Hunminjeongeum itself. Along the way: Jang Yeong-sil, a government slave who built the king's self-striking water clock, and the rain gauge that the court record credits to the crown prince.

Five Centuries Later ⓘ No fictional characters are used: every person named is real. All faces are imagined — no portrait of King Sejong from his lifetime survives. Scenes illustrate documented events; their rooms, weather and gestures are reconstructions. Every quotation comes from a real document (the Annals of the Joseon Dynasty or the Hunminjeongeum Haerye). The English translations are our own, made from the Classical Chinese originals. How much help Sejong had in designing the letters is still debated by historians, and the video says so. Illustrations are AI-generated (illustrated, not photographic reconstructions) and the narration uses a synthetic voice. Script, research and editing by the channel.
