To the north of the Chams, the country from an early period was occupied by the Lawa, a race with Mon affinities and probably of the Mon stock, who, according to their own traditions, and the beliefs and traditions of their neighbours, are the aborigines of the region stretching southwards from Yunnan, and eastwards from the Salween to the Meh Kong, and perhaps even to the China Sea. Many of the names of principalities and deserted cities are said to have been derived from the Lawa; and fierce battles were fought between them and the Shans before the former were conquered or driven into the hills. In a few years the language of this interesting race will be extinct, as the race have gradually been absorbed into the Shan and Peguan population, and Shan as well as Lawa is now being spoken in their few remaining distinct villages. To the west of the Lawa were the Mon or Mun, a Mongoloid race of Malaysian affinities, whose scattered tribes spread from Indo-China into Western Bengal and Central India, where they are now known as Kolarian. Their first kingdom in Lower Burmah was founded at Thatone, an ancient seaport on the east of the Gulf of Martaban, by an Indian dynasty from the Madras coast, in the sixth century B.C. About the end of the first century of our era, Mon tribes drove the Burmese from Prome, which had been their capital from B.C. 483. These tribes were probably descendants of the Ngu race, including the Pang, Kuei, and Miao tribes, who, with the Shan, Yang or Karen, and King or Chin tribes, formed the chief part of the population of Central and Southern China during the struggle for empire—604–220 B.C.—between the Dukes of Tsi, Dsin, Ts’in, and Tsoo, which ended in the ruler of Ts’in becoming the first Supreme Emperor of China. Some of the wars waged by Ts’in during this period seem to have been wars of extermination; and many tribes must have sought safety by moving southward and south-westward out of the area of turbulence. In one campaign 240,000 heads are said to have been cut off; in another, 140,000; and in others, 60,000, 80,000, and 82,000 heads. In A.D. 573, the Mon founded a separate kingdom at Pegu, which, with the Thatone kingdom, was destroyed by the Burmese King of Pugan in the middle of the eleventh century; from that time to 1287, when Pegu was conquered by the Shan King of Martaban, Lower Burmah remained under the Burmese. In 1540 it was reconquered by the latter, and formed part of their empire for 200 years. In 1740 the Mon, aided by the Karen and Gwe Shan, rebelled against Burmah, and, electing a Gwe Shan as their king, commenced the great fight for supremacy, which lasted till 1757, and left the Burmese supreme in the country until we annexed it.
