The Khmer capital at Angkor is the center of a powerful, opulent empire that includes most of continental Southeast Asia. The Angkor period is noted for the vast number of breathtaking monuments constructed from the late ninth to the thirteenth century. Ranging from relatively small structures to the gigantic Baphuon and Angkor Wat, these temple-mountains are profusely decorated with sculptures, which are used to provide a relative chronology for other works from the same periods. Angkor hegemony is challenged in the middle of the fourteenth century with the rise of new kingdoms in Laos and Thailand. The establishment of the kingdom of Majapahit in eastern Indonesia in the thirteenth century marks one of the high points of unification in island Southeast Asia. Sculptures, many of large scale, and metalwork are the most important artistic traditions during the period.
