Cao Dai's Holy See and Private Army
At Tay Ninh, Lewis visited the Holy See of Cao Dai, a recent syncretic religion. It combined Buddhism, Taoism, Confucianism and Catholicism, had its own pope, and revered saints including Victor Hugo, with messages received through spirit séances. The sect also kept a private army and a semi-autonomous territory, and the French tolerated and armed it as a counterweight to the Viet Minh, so a colonial power ended up relying on an armed millenarian church to hold its countryside.
