勤王運動
Phan continued to seek support from the scholar-gentry and the bureaucracy serving the French, before shifting his focus to obtaining support from members of the imperial family. Phan had moved to Huế, claiming that he was preparing for the metropolitan imperial examinations, but in actuality, he planned on drumming up support among the various factions of royal family. Phan traveled to Quảng Nam to meet with Nguyễn Thành, a contemporary anti-colonial revolutionary activist who was involved in the Cần Vương movement. Thành suggested that a royal associate of his, Tôn Thất Toại, could help lead the revolution. Phan rejected the offer, but took Thành's advice to seek support from direct descendants of Emperor Gia Long, the founder of the Nguyễn Dynasty. These direct descendants were still highly respected by wealthy Mekong Delta landowners who Phan hoped would raise the bulk of the money needed to finance the revolution.
