Early history (to the 9th century)
Prehistory
About 1500 BCE, people in the region were turning copper into bronze, growing rice, and domesticating chickens and pigs; they were among the first people in the world to do so. By 500 BCE, iron-working settlements emerged in an area south of present-day Mandalay. Bronze-decorated coffins and burial sites filled with earthenware remains have been excavated. Archaeological evidence at Samon Valley south of Mandalay suggests rice growing settlements that traded with China between 500 BC and 200 CE. During the Iron Age, archaeological evidence also out of Samon Valley reveal changes in infant burial practices that were greatly influenced by India. These changes include burying infants in jars in which their size depict their family status.
Pyu city-states
The Pyu entered the Irrawaddy valley from present-day Yunnan, c. 2nd century BCE, and went on to found city states throughout the Irrawaddy valley. The original home of the Pyu is reconstructed to be Qinghai Lake in present-day Qinghai and Gansu. The Pyu were the earliest inhabitants of Burma of whom records are extant. During this period, Burma was part of an overland trade route from China to India. Trade with India brought Buddhism from South India. By the 4th century, many in the Irrawaddy valley had converted to Buddhism. Of the many city-states, the largest and most important was the Sri Ksetra Kingdom southeast of modern Pyay, also thought to once be the capital city. In March 638, the Pyu of Sri Ksetra launched a new calendar that later became the Burmese calendar.Eighth-century Chinese records identify 18 Pyu states throughout the Irrawaddy valley, and describe the Pyu as a humane and peaceful people to whom war was virtually unknown and who wore silk cotton instead of actually silk so that they would not have to kill silkworms. The Chinese records also report that the Pyu knew how to make astronomical calculations, and that many Pyu boys entered the monastic life at seven to the age of 20.
It was a long-lasting civilisation that lasted nearly a millennium to the early 9th century until a new group of "swift horsemen" from the north, the Bamars, entered the upper Irrawaddy valley. In the early 9th century, the Pyu city states of Upper Burma came under constant attacks by Nanzhao (in modern Yunnan). In 832, the Nanzhao sacked Halingyi, which had overtaken Prome as the chief Pyu city-state and informal capital. Archaeologists interpret early Chinese texts detailing the plundering of Halingyi in 832 to detail the capturing of 3000 Pyu prisoners, later becoming Nanzhao slaves at Kunming.
While Pyu settlements remained in Upper Burma until the advent of the Pagan Empire in the mid 11th century, the Pyu gradually were absorbed into the expanding Burman kingdom of Pagan in the next four centuries. The Pyu language still existed until the late 12th century. By the 13th century, the Pyu had assumed Bamar ethnicity. The histories/legends of the Pyu were also incorporated to those of the Bamars.
Mon kingdoms
According to the colonial era scholarship, as early as the 6th century, another people called the Mon began to enter the present-day Lower Burma from the Mon kingdoms of Haribhunjaya and Dvaravati in modern-day Thailand. By the mid 9th century, the Mon had founded at least two small kingdoms (or large city-states) centred around Bago and Thaton. The earliest external reference to a Mon kingdom in Lower Burma was in 844–848 by Arab geographers. But recent research shows that there is no evidence (archaeological or otherwise) to support colonial period conjectures that a Mon-speaking polity existed in Lower Burma until the late 13th century, and the first recorded claim that the kingdom of Thaton existed came only in 1479.Read More...
