This article examines the significance of Buddhism in the insurgency that followed the annexation of the kingdom of Burma in 1886, demonstrating that Buddhism was a critically important part of the Burmese polity and identity. Moreover, it indicates that opposition to the British after the full colonisation of Burma was not only instantaneous, but also fuelled primarily by Buddhist sentiment. This challenges the prevailing notion that anti-colonialism in Burma – Buddhist-inspired or otherwise – was a twentieth century phenomenon. Beginning with the pre-colonial era, the article explores the intimate connection between Buddhism, the Burmese polity and the national psyche. The critical importance of the Buddhist king is emphasised in particular. When the kingdom of Burma was annexed in 1886, opposition to the British manifested itself instantaneously in the form of rebellions and insurgency. This period, sometimes referred to as the “pacification”, has been often ignored in studies. The article, using British colonial documents, shows clearly the importance of Buddhist sentiment in these uprisings as a response to the abolition of Burma's last Buddhist king. Buddhist themes present in translated rebel proclamations, as well as the widespread participation of Buddhist monks corroborate this.
