named Isanavarman I. And like the Cambodian kings, he traced his ancestry to the legendary Kamma Kshtriya King from Kakatiya kingdom and the nāga-princess Soma. Later developments Subsequent kings renovated the older temples and constructed additional ones. For many centuries, the building of temples and shrines of varying sizes continued, and Mỹ Sơn served as the religious and cultural center of the Cham civilization in central Vietnam, as well as the burial place of kings and religious leaders. Most of the extant temples at Mỹ Sơn, such as the Isanabhadresvara, were built in the late 10th century and 11th century AD by king Harivarman II (r. 989–997) and later king Harivarman IV (r. 1074–1080). The inscriptions from this period have not survived, except in fragmentary form. At the beginning of the 10th century, the Cham center of power was at Đồng Dương, not far from Mỹ Sơn. By the end of the century, it had been displaced southward to Bình Định Province on account of military setbacks in wars with the Viet. However, Cham kings continued periodically to renovate the temples at Mỹ Sơn and even to build new foundations. The latest significant Cham record at Mỹ Sơn is a pillar inscription of King Jaya Indravarman V dated 1243 AD. By the early 15th century, the Cham had lost their northernmost lands, including the area of Mỹ Sơn, to the Viet. Modern scholarship Following the conquest of central Vietnam by Vietnamese emperor Le Thanh Tong which reduced the status of Champa kingdoms to autonomous subordinate regions and the decline and eventual fall of Champa, the Mỹ Sơn complex fell into disuse and was largely forgotten. Vietnamese people settled and built villages, towns, cities on conquered Cham lands. It was rediscovered in 1898 by the Frenchman . A year later, members of the scholarly society called École française d'Extrême-Orient (EFEO) began to study the inscriptions, architecture, and art of Mỹ Sơn. In 1904, they published their initial findings in the journal of the society called Bulletin de l'École française d'Extrême Orient (BEFEO). Henri Parmentier gave a description of the ruins at Mỹ Sơn, and M. L. Finot published the inscriptions that had been found there. Restoration In 1937, French scholars began to restore the temples at Mỹ Sơn. In 1937 and 1938, the main temple known as "A1" and the smaller temples surrounding it were restored. Other major temples were restored
