As Confucianism spread and matured on the Korean Peninsula, family precepts for Confucian education were developed in the Joseon dynasty (1392-1897). Initial statistics have yielded 296 family precepts dated from the Yeongnam area. They were penned by some 139 authors writing in different formats and genres, including letters, prose, verse, mottos, and inscriptions. This paper is an exploration of the genres and construction of Yeongnam family precepts. It also analyzes how the content of Confucian classics served as foundations for family precepts that were intended to be handed down to later generations. This practice was an important boost for Confucianism to become national value of the Korean people.
