Abstract

• Kabaw valley was one of the territories under the Pyu kings (Myanmar) since Pyu period (from 5th century BC to 9th century AD). Besides, it was also one of the territories under the Myanmar kings since Bagan period (from 9th century AD to 13th century AD). Therefore, Kabaw valley is as part of Ancient Myanmar History. So, Kabaw valley is an important area for Myanmar History. Moreover, Kabaw valley (Kabaw Chaung in Myanmar sources) is an interesting area for researchers in history and archaeology because it has old city sites namely Kalay, Yazagyo, Khampat and Thaungdut. According to some data made by field survey research, these old cities came into existence during the Pyu period and were destroyed and then they were re-built during the Bagan period. Since then, these old cities continued to exist until Konbaung period (AD 1752 1885). Some of these old cities were very important ones for military purpose to northern part of Myanmar.
