Unlike other multi-ethnic nations, such as Myanmar and India, where official language policy has sparked bloody clashes, Thailand has maintained relative stability despite its eighty languages. In this study of the relations among politics, geography, and language, William A. Smalley shows how Thailand has maintained national unity through an elaborate social and linguistic hierarchy.

Smalley contends that because the people of Thailand perceive their social hierarchy as the normal order, Standard Thai, spoken by members of the higher levels of society, prevails as the uncontested national language. By examining the hierarchy of Thailand's diverse languages and dialects in light of Thai history, education, culture, and religion, Smalley shows how Thailand has been able to keep its many ethnic groups at peace.

Linguistic Diversity and National Unity explores the intricate relationship between language and power and the ways in which social and linguistic rank can be used to perpetuate order.

In February of 1971, in the Laotian village of Nam Chia, a forty-one year old farmer named Shong Lue Yang was assassinated by government soldiers. Shong Lue claimed to have been descended of God and given the mission of delivering the first true Hmong alphabet. Many believed him to be the Hmong people's long-awaited messiah, and his thousands of followers knew him as "Mother (Source) of Writing."

An anthropological linguist who has worked among the Hmong, William A. Smalley joins Shong Lue's chief disciple, Chia Koua Vang, and one of his associates, to tell the fascinating story of how the previously unschooled farmer developed his remarkable writing system through four stages of increasing sophistication. The uniqueness of Shong Lue's achievement is highlighted by a comparison of Shong Lue's writing system to other known Hmong systems and to the history of writing as a whole.

In addition to a nontechnical linguistic analysis of the script and a survey of its current use, Mother of Writing provides an intriguing cultural account of Shong Lue's life. The book traces the twenty-year-long struggle to disseminate the script after Shong Lue's death, first by handwriting, then by primitive moveable type, an abortive attempt to design a wooden typewriter, and finally by modern wordprocessing. In a moving concluding chapter, Smalley discusses his own complex feelings about his coauthors' story.
