Cần Vương movement
Tường and his colleagues then installed the 37-year-old Hiệp Hoà. However, the new emperor was aware of their faults, so he decided to steer clear of them. As a result, they wanted to dispose of him. Hiệp Hoà then made a deal with the French so that they would protect him, fearful of the regents. However, when the French were absent, the regents put Hiệp Hoà to death. They then replaced him with Kiến Phúc. Kiến Phúc caught Tường with Học Phi and vowed to kill them for their conduct. Học Phi poisoned Phúc's medicine and he died the next day. Hàm Nghi was eventually installed as the emperor, and Thuyết decided to launch the Cần Vương movement, an uprising against the French. Thuyết took Hàm Nghi to a mountain base at Tan So, and then went to China to hide and seek reinforcements. In the meantime, the French installed Đồng Khánh on the throne.
