more details about last Invasion by Burmese:
Bodawpaya was the sixth king of the
Konbaung Dynasty of
Burma. Born
Maung Shwe Waing and later
Badon Min, he was the fourth son of
Alaungpaya, founder of the dynasty and the Third Burmese Empire.
known as
Bodaw U Waing, he invaded
Arakan in 1784 sending his royal armies led by his son, the Heir Apparent
Thado Minsaw, across the Western Yoma range of mountains. The capital of Arakan
Mrauk U was captured on the last of 1784. The
Mahamuni Buddha image, among other treasures such as the
Khmer bronze statues, were brought back to mainland Burma; these can still be seen in
Mandalay. Also taken were 20,000 captives as slaves to pagodas and temples, and the nobility at Amarapura. Once Arakan was annexed as a province of Burma, her borders became contiguous with
British India.
You claim that British period ppl can not considered Burma's ppl when yourself invader of Arakan before British.
Such an irony. You burmese were always outsiders. Not to mention your invasion in Assam and other parts of the region. you guys were always been aggressor.
