Proselytism was officially frowned upon in the Indian Empire. Conversion from one religion to another was highly political and potentially explosive. The Wesleyan missionaries' teetotalism and modest stipends separated them from colonial neighbours. World War I disturbed a period of relative calm in Upper Burma. The Wesleyan missionaries were relatively ignorant about rural politics and were generally less sympathetic. The Wesleyans were perplexed because pongyis were poisoning the minds of ordinary 'Burman Buddhists'. Even the American Baptists were shaken by Buddhist truculence in the towns. The Hsaya San rebellion broke out in Lower Burma at the end of December 1930. The Marxist-dominated All Burma Students' Union (ABSU) and Dobama Asiayone (We Burmans) expanded rapidly during the 1930s. Dobama had begun as a student political movement in 1933 but quickly embraced industrial workers and cultivators.
Politics and religion were two sides of the same coin. Wesleyan missionaries went to Upper Burma for many and complex reasons but their main purpose was to convert Burmans to Christianity. Religious conversions caused bitter divisions within colonial communities. Wesleyans in Burma, for example, often suspected new converts of seeking social or political preferment. Wesleyans in Upper Burma discovered that Indian street sweepers and lepers were most easily proselytised. Winston described Buddhist Burmans as primitive, backward and crude. In 1904, despondent Wesleyan missionaries complained that the Burmese national character had been 'formed by generations of loose morality.' Wesleyan attitudes softened as the Burmans became more compliant. Many of the younger missionaries were captivated by their 'confiding, simple nature'. During the 1920s, the transformation was evident in the bazaars and backstreets of Upper Burmese towns. Spiritual confrontations between Christians and Buddhists became intensely political.
Everyone suffered some pain when Burma lurched from past into present, and the prize was plucked from old sparring partners. Democracy is the most potent issue in modern Myanmar. Many Burmans and Western liberals regard democratisation as the prerequisite for development. The survival of the Methodist Church in Buddhist Upper Burma is little short of a miracle. There were only slightly fewer members in the Mandalay District in 2006 than there were in 1900. After 1966 it became impossible for the Church to proselytise, and it has survived only by retaining existing members. Missionary voices rarely challenged government policies either in colonial times or in Independent Burma. Maitrii Aung-Thwin defines Burma's past, present and future as a complicated potion of personalities, intellectual influences, culture and political forms. Charney is right to identify Buddhist monks as the custodians of 'Burmese tradition and the core of Burmese intellectual life'.
The Wesley high schools were extraordinarily successful during the early years of the twentieth century. The Colonial Government was investing heavily in education. It encouraged mission schools generally and it was particularly impressed by the Wesley high schools. The Wesleyan schools quickly became academic powerhouses, renowned for progressive teaching, firm discipline and high moral values. In 1911 Buddhist elders requested Rev. Edgar Bradford to start a Wesleyan Anglo-Vernacular School in Salin, a prosperous town south of Pakokku. Bradford obliged and a school was opened in 1912. Wesleyan education in Upper Burma reached its zenith in 1917 when 2,216 pupils had registered in thirty schools. The student disturbances of 1938–39 damaged several successful mission schools in Upper Burma and separated them from their surrounding communities. In 1944, the exiled Governor, Sir Reginald Dorman Smith, promised that Methodist mission schools would be returned to their former glory after the war.
The Roman Catholic Convent was the only school in Mandalay that catered specifically for Eurasian girls. A.W. Bestall launched a furious campaign to persuade the Missionary Committee to provide funds for a Wesleyan Eurasian girls' school in Mandalay. The missionaries were also very interested in certain aspects of public health, but their preoccupations were extremely selective. Leprosy melted hearts in Victorian England. One other social problem was entirely new. Wayward Burmese adolescents were addicted to films. They may have picked up the bad habit from the missionaries' magic-lantern shows, where mesmerised audiences gawped at cartoon Bible stories. Although leprosy brought the lives of individual sufferers crashing down, it was not the most important health problem in Burma. It was a political issue. In 1900 the missionaries asked the Missionary Society to send a missionary doctor. In 1911 Bradford described the hospital in Pakokku, a 'congested town, which is unsanitary'.
