This is a wide-ranging study of vernacularization in East Asia - not only China, Japan, Korea, and Vietnam, but also societies that no longer exist, such as the Tangut and Khitan empires. Peter Kornicki takes the reader from the earlycenturies of the common era, when the Chinese script was the only form of writing and Chinese Buddhist, Confucian, and medical texts spread throughout East Asia, through the centuries when vernacular scripts evolved, right up to the end of the nineteenth century when nationalism created new roles for vernacular languages and vernacular scripts.
