The research was conducted based on original documents, such as letters, archives, and monographs from the French-Spanish alliance invaded Vietnam until the signing of the agreement dated October 1, 1888. The results show that, from 1858, with the plot to annex and establish a colony in Vietnam, the French colonialists allied with Spain to attack Da Nang. After defending the Nguyen dynasty, the French colonialists quickly planned and setted up concessions in the Tonkin and Central of Vietnam. Da Nang from a provincial administrative unit under the Nguyen dynasty became a concession area with its own legal, administrative and regulatory system of the French colonial government. Based on the research results, the article will contribute to clarifying the difficulties and challenges of the French colonialists in the early invasion of Vietnam. In addition the article will point out the French colonialists' attempts to force the Nguyen dynasty to sign treaties to turn Da Nang into a concessions area.
