Discussion of the rules, customs, and the concept of royal succession in Southeast Asia. A vital principle of Southeast Asian history, the monarchical concept, has often been explored with only passing reference to succession. In this paper the author attempts to fill in some gaps in recent scholarship, noting that "while the concept of kingship is stable and unitary, the forms and circumstances of succession vary through crisis and coincidence; some of these changes are due to the defaults and limitations of kingly power, and others, to internal weaknesses resulting from adherence to traditional principles. The moment of succession is a critical fulcrum, at a time when innovation may alter or restore the equilibrium of the realm." 13 pp.
