Lower Myanmar Lower Myanmar Lower Burma (, also called Outer Myanmar) is a geographic region of Burma (Myanmar) and includes the low-lying Irrawaddy delta (Ayeyarwady, Bago and Yangon Regions), as well as coastal regions of the country (Rakhine and Mon States and Tanintharyi Region). In the Burmese language, people originating from Upper Burma are typically called "a-htet-tha" for men and "a-hiet-lhu" for women, whereas those from Lower Burma are called "auk tha" () for men and "auk thu" for women. While "a-nya tha" () refers to interior inhabitants of the country. Historically, Lower Burma referred to the part of Burma annexed by
Bago, Negros Occidental under which a native prince Mapagic died according to the writings of a Spanish historian, Diego de Povedano. Another version, however, noted that the name came from the shrub, "bago-bago" that grew abundantly in the riverbanks. Around the 17th and 18th Centuries, settlers from Molo, Iloilo formed a little village at the mouth of Bago River, presently a rich source of sand and gravel. The village grew into a large settlement prompting its elders to pass a petition for its conversion into a town or "pueblo", which was granted in 1800. Its history has its beginning on September 6, 1571
