Sidoktaya
Sidoktaya is one of the oldest ancient towns in Myanmar. It is established by Prince Yazakumar (a. Min Zaya Khittaya or Min Thiri Khittaya) in Year 460 (Myanmar Era) (about 1098 A.D.). Now it is over 900 years of age. there are many archaeological places including Si-kyek-taung Pagoda, Aung-kyar Thiri Pagoda, and Sutaungpyi Pagoda. The ancient city wall had been found buried in some places.
Early Pagan Kingdom
However, some scholars believe that Burmans had arrived in Myanmar much earlier than the mainstream opinion holds. Htin Aung contends that the arrival of Burmans may have been a few centuries earlier, perhaps the early 7th century. Historians Michael Aung-Thwin and Matrii Aung-Thwin write that the 19 villages that first formed the city of Pagan according to the chronicles are "probably" "legendary" but "the origins of the Burmese speakers in Myanmar may well be earlier than, and had nothing to do with, the Nanzhao raid of AD 832".
