Hangeul

The Korean alphabet, also known as Hangul, or Chosongul (officially transcribed Han-geul in South Korea and Chosŏn'gŭl in North Korea), is the native alphabet of the Korean language. It was created during the Joseon Dynasty in 1443, and is now the official script of both South Korea and North Korea, and co-official in the Yanbian Korean Autonomous Prefecture of China's Jilin Province. In South Korea, Hangul is sometimes augmented by Chinese characters, called hanja, whereas in North Korea, hanja is virtually nonexistent.
