The movement to expel the Manchus, who had seized the Dragon Throne in 1644 from the expiring Ming Dynasty, was an old one. Historians are silent on the subject of the various secret plots which were always being hatched to achieve that end, their silence being due to a lack of proper records and to the difficulty of establishing the simple truth in a country where rumour reigns supreme. But there is little doubt that the famous Ko-lao-hui, a Secret Society with its headquarters in the remote province of Szechuan, owed its origin to the last of the Ming adherents, who after waging a desperate guerilla warfare from the date of their expulsion from Peking, finally fell to the low level of inciting assassinations and general unrest in the vain hope that they might some day regain their heritage.
