Rakhine State occupies the northern coastline of Myanmar up to the border with Bangladesh and corresponds to the historical Kingdom of Arakan. The history of Rakhine is divided into 7 parts - the independent kingdoms of Dhanyawadi, Waithali, Lemro, Mrauk U.
Rakhine's ancient kingdoms are divided into four separate periods.
Arakanese legends claim that the history of the Rakhine people began in 3325 BC, although archaeological evidence supporting this claim is unavailable. "The presently dominant Rakhine are a Tibeto-Burman race, the last group of people to enter Arakan during 10th century and on.” (Pamela; The Lost Kingdom, Bangkok, 2002, P-5)]. Various Arakanese kingdoms stretched from the Ganges Delta to Cape Negrais on the Irrawaddy Delta.
Ancient Dhanyawadi lies west of the mountain ridge between the Kaladan and Le-mro rivers. Dhannyawadi could be reached by small boat from the Kaladan via its tributary, the Tharechaung. Its city walls were made of brick, and form an irregular circle with a perimeter of about 9.6 kilometres (6.0 miles), enclosing an area of about 4.42 km2 (1,090 acres). Beyond the walls, the remains of a wide moat, now silted over and covered by paddy fields, are still visible in places. The remains of brick fortifications can be seen along the hilly ridge which provided protection from the west. Within the city, a similar wall and moat enclose the palace site, which has an area of 26 hectares (64 acres), and another wall surrounds the palace itself.
At times of insecurity, when the city was subject to raids from the hill tribes or attempted invasions from neighbouring powers, there would have been an assured food supply enabling the population to withstand a siege. The city would have controlled the valley and the lower ridges, supporting a mixed wet-rice and taungya (slash and burn) economy, with local chiefs paying allegiance to the king.
From aerial photographs we can discern Dhannyawadi's irrigation channels and storage tanks, centred at the palace site. Throughout the history of Rakhine, and indeed the rest of early Southeast Asia, the king's power stemmed from his control of irrigation and water storage systems to conserve the monsoon rains and therefore to maintain the fertility and prosperity of the land. In ceremonies conducted by Indian Brahmins the king was given the magic power to regulate the celestial and terrestrial forces to control the coming of the rains which would ensure the continuing prosperity of the kingdom.
