Phan Xích Long, a leader of a messianic movement in early 20th century Vietnam, proclaimed himself the Emperor of Vietnam in a bid to resist French colonial domination. His announcement captured the imagination of many who were disillusioned with foreign rule and sought national liberation. Long organized a revolt that aimed to rally the Vietnamese populace against the colonial administration. French authorities, perceiving the growing unrest as a threat, swiftly moved to arrest him on charges of inciting rebellion. Despite his imprisonment, the fervor ignited by Long's proclamation did not wane. His supporters were determined to carry on with the revolt, believing that their leader’s vision would guide them to freedom. The following day, these supporters initiated their planned revolt, demonstrating their commitment to the cause and their belief in Long’s leadership. This act of defiance highlighted the rising anti-colonial sentiments that were circulating in Vietnam during this time.
