The yangban were part of the traditional ruling class or gentry of dynastic Korea during the Joseon Dynasty. The yangban were mainly composed of highly educated civil servants and military officers—landed or unlanded aristocrats who individually exemplified the Korean Confucian form of a "scholarly official". They were largely government administrators and bureaucrats who oversaw medieval and early modern Korea's traditional agrarian bureaucracy until the end of the dynasty in 1897. In a broader sense, an office holder's family and descendants, as well as country families who claimed such descent, were socially accepted as yangban.

Korean is the native language for about 81 million people, mostly of Korean descent. It is the official and national language of both North Korea and South Korea. The language has notable differences in each of the Koreas, in part owing to different official standardizations of the language. They are still largely mutually intelligible, however. South Korean newspaper Daily NK has claimed North Korea criminalizes the use of the South's standard language with the death penalty, and South Korean education and media often portray the North's language as alien and uncomfortable.
