The Kingdom of Champassak was founded in 1713 in what is now southern Laos, and its royal lineage, the House of Champassak, continues to the present. In this historical study of Champassak, Ian G. Baird explores the ways it has asserted its sovereignty across time and through monumental historical shifts, including the delineation of national boundaries for Laos, Thailand, and Cambodia in the nineteenth and twentieth centuries.

In re-creating this story, Baird draws not only on a dazzling variety of primary sources in English, French, Lao, and Thai but also on many years spent in conversation with members of the Na Champassak family, who are now spread across a wide geographical area, from Laos and Thailand to France and the United States. Each chapter treats one historical period, identifying the Champassak approach to sovereignty during that time. Through this deep history, Baird shows how sovereign power, even within one case, takes a wide range of forms, always contingent, contested, and uneven across space and time.
