From Rohingya wiki--so--Thant Myint U switched sides?

According to Thant Myint-U, historian and adviser to President Thein Sein, "At the beginning of the 20th century, Indians were arriving in Burma at the rate of no less than a quarter million per year. The numbers rose steadily until the peak year of 1927, immigration reached 480,000 people, with Rangoon exceeding New York City as the greatest immigration port in the world. This was out of a total population of only 13 million; it was equivalent to the United Kingdom today taking 2 million people a year." By then, in most of the largest cities in Burma, Rangoon, Akyab, Bassein and Moulmein, the Indian immigrants formed a majority of the population. All of Burma was officially a Province within the British Indian Empire ('the Raj') from November 1885 until 1937, when Burma became a separate Crown colony within the British Empire. The Burmese under British rule felt helpless, and reacted with a "racism that combined feelings of superiority and fear".[137] Professor Andrew Selth of Griffith University writes that although a few Rohingya trace their ancestry to Muslims who lived in Arakan in the 15th and 16h centuries, most Rohingyas arrived with the British colonialists in the 19th and 20th centuries.[138][139] Most have argued that Rohingya existed from the four waves of Muslim migrations from the ancient times to medieval, to the British colony. Gutman (1976) and Ibrahim (2016) claiming that the Muslim population dates before the arrival of ethnic Rakhine in the 9th to 10th century. Suggesting the Rohingya are descendants of a pre-Arakan population who existed for 3 thousand years and waves of Muslim who intermingled forming modern Rohingya.[140]
