Throughout the colonial era, many Indians arrived as soldiers, civil servants, construction workers and traders and, along with the Anglo-Burmese community, dominated commercial and civil life in Burma. Rangoon became the capital of British Burma and an important port between Calcutta and Singapore. Burmese resentment was strong, and was vented in violent riots that paralysed Rangoon on occasion until the 1930s. Some of the discontent was caused by a disrespect for Burmese culture and traditions such as the British refusal to remove shoes when they entered pagodas. Buddhist monks became the vanguards of the independence movement. U Wisara, an activist monk, died in prison after a 166-day hunger strike to protest against a rule that forbade him to wear his Buddhist robes while imprisoned.
