When, in 1926, N. J. Krom published his standard study of the Hindu-Javanese period in Indonesian history, a major gap in the historiography of the Archipelago seemed to have been filled. Krom's later publications enlarged expertly upon the major themes of his great work. He seemed content to catalogue and analyze the many Indonesia inscriptions, statues, and temples, dating from the fifth to the fifteenth centuries A.D. which he regarded as the fruit of the Hinduization of Java and Sumatra. In his earlier study of Hindu-Javanese art, he brilliantly revealed the mingling of indigenous traditions with the technique of Hindu and Hinduized artisans in the Sumatran and Javanese kingdoms. The dominant note in all his writings was the great civilizing influence which he claimed had been exerted by Hindu traders and colonists over the supposedly untutored indigenous population of the Greater Sunda islands. Though willing to admit that the inhabitants of Java and Sumatra before the coming of the Hindus were not “savages” and that they possessed a certain knowledge of political organization, and agricultural and metallurgical technique, Krom emphasized that the high civilization reached by the kingdoms of Java and Sumatra between the ninth and thirteenth centuries was largely due to the infiltration of Hindu culture.
