How Ngo Van Chieu Declared the Founding of Cao Dai

A spiritualist circle of colonial civil servants in Saigon had been meeting since 1925, drawn together by seance practice that would go on to give the new religion its earliest shape and its earliest following. On 7 October 1926 that circle's practice crystallized into something formal when Ngo Van Chieu signed the Declaration of the Founding of the Cao Dai Religion, an act soon followed by official recognition centered at Tay Ninh in southern Vietnam.

Ngo Van Chieu's own signature turned a private spiritualist circle into a religion carrying a declared founding date and a declared founder, a status no informal gathering of seance participants could claim while it remained unofficial. The recognition that followed at Tay Ninh gave the new faith a geographic center to organize and grow from, rather than leaving it scattered among the civil servants who had first practiced it together in Saigon.

What the declaration changed for Cao Dai's spread was speed. Growth from that 1926 founding proved rapid enough that within fourteen years the young religion counted more than a million followers, between a fifth and a fourth of the entire population of Cochinchina, a scale reached within a single generation of the declaration that had first given the movement its formal existence and its first organized following.
