Бао Дай
Emboldened by his success, Diệm began to plot Bảo Đại's downfall. He scheduled a referendum for 23 October 1955 and pushed Bảo Đại out of the political scene, hindering the former emperor's attempts to derail the poll. In the period leading up to the vote, campaigning for Bảo Đại was banned, while Diệm's election campaign focused on personal attacks against Bảo Đại. These included pornographic cartoons of the head of state and unverified rumours claiming he was illegitimate and linking him to various mistresses. The government-controlled media launched polemical attacks on Bảo Đại, and police went door-to-door, warning people of the consequences of failing to vote. After his brother Ngô Đình Nhu had rigged the referendum, Diệm proclaimed himself president of the newly created Republic of Vietnam.
