By the turn of the century, a whole generation of Vietnamese had grown up under French control. The people continued, as in precolonial times, to look to the scholar-gentry class for guidance in dealing with French imperialism and the loss of their country's independence. A few scholar-officials collaborated with the French, but most did not. Among those who refused was a group of several hundred scholars who became actively involved in the anticolonial movement. The best known among them was Phan Boi Chau, a scholar from Nghe An Province, trained in the Confucian tradition under his father and other local teachers. In 1885 Phan Boi Chau observed at close range the actions of French troops in crushing scholar-gentry resistance to the colonial overlords. For the next decade he devoted himself to his studies and finally passed the regional examination with highest honors in 1905. During the following five years, he traveled about the country making contacts with other anticolonial scholars and seeking out in particular the survivors of the Can Vuong movement, with whom he hoped to launch a rebellion against the French. He also sought to identify a member of the Nguyen ruling family sympathetic to the cause, who would serve as titular head of the independence movement and as a rallying point for both moral and financial support. Chosen to fill this role was Cuong De, a direct descendant of Gia Long.

In 1904 Phan Boi Chau and about twenty others met in Quang Nam to form the Duy Tan Hoi (Reformation Society), the first of a number of revolutionary societies he organized. The following year, he went to Japan to meet with Japanese and Chinese revolutionaries and seek financial support for the Vietnamese cause. The Japanese defeat of the Russian fleet at Tsushima the month before his arrival had caused great excitement among the various Asian anticolonialist movements. Phan Boi Chau brought Cuong De, along with several Vietnamese students, to Japan in 1906. That same year he convinced the other great Vietnamese nationalist leader of the period, Phan Chu Trinh, to visit him in Tokyo. After two weeks of discussions, however, they were unable to resolve their basic tactical differences. Whereas Phan Boi Chau favored retaining the monarchy as a popular ideological symbol and a means of attracting financial support, Phan Chu Trinh wanted primarily to abolish the monarchy in order to create a base on which to build national sovereignty. Furthermore, he was greatly influenced by the writings of French political philosophers Rousseau and Montesquieu, and he believed that the French colonial administration could serve as a progressive force to establish a Western democratic political structure through peaceful reform. Phan Boi Chau, conversely, wanted to drive out the French immediately through armed resistance and restore Vietnamese independence.

In 1907 Phan Boi Chau organized the Viet Nam Cong Hien Hoi (Vietnam Public Offering Society) to unite the 100 or so Vietnamese then studying in Japan. The organization was important because of the opportunity it provided fo 2000 or the students to think and work together as VietnamÍÍÍÍÍÍÍÍese, rather than as Cochinchinese, Annamese, or Tonkinese, as the French called them. The following year, however, the Japanese, under pressure from the French, expelled the students, forcing most of them to return home. In March 1909, Phan Boi Chau was also deported by the Japanese. He went first to Hong Kong, later to Bangkok and Guangzhou. Even during his years abroad, his writings served to influence nationalist activities in Vietnam. In 1907 the Dong Kinh Nghia Thuc (Free School of the Eastern Capital [Hanoi]) was founded to educate nationalist political activists. Phan Boi Chau's writings were studied and Phan Chu Trinh gave lectures at the school. Suspecting that Phan Boi Chau was associated with the school, however, the French closed it in less than a year. The French also blamed Phan Boi Chau for instigating antitax demonstrations in Quang Nam and Quang Ngai provinces and in Hue in early 1908. As a symbol of the movement, the demonstrators forcibly cut off men's traditional long hair. An abortive Hanoi uprising and poison plot in June 1908 was also blamed on Phan Boi Chau. In response to the uprising, the French executed thirteen of the participants and initiated a crackdown on Vietnamese political activists, sending hundreds of scholar-patriots, including Phan Chu Trinh, to prison on Poulo Condore (now Con Dao). A major expedition was also launched in 1909 against De Tham, a resistance leader who was involved in the Hanoi uprising. De Tham, who had led a thirty-year campaign against the French in the mountains around Yen The in the northeastern part of Tonkin, managed to hold out until he was assassinated in 1913.

Stimulated by the Chinese Revolution led by Sun Yat-sen in 1911, Phan Boi Chau and the other Vietnamese nationalists in exile in Guangzhou formed a new organization in 1912 to replace the moribund Duy Tan Hoi. The main goals of the newly organized Viet Nam Quang Phuc Hoi (Vietnam Restoration Society) included expulsion of the French, recovery of Vietnamese independence, and establishment of a "Vietnamese democratic republic." Phan Boi Chau had by this time given up his monarchist position, although Cuong De was accorded presidential status within the organization's provisional government. In order to gain support and financial backing for the new organization, Phan Boi Chau organized a number of terrorist bombings and assassinations in 1913, to which the French responded harshly. By 1914 the counterrevolutionary government of Yuan Shi-kai was in charge in China, and, by French request, Phan Boi Chau and other Vietnamese exiles in that country were imprisoned.

World War I began shortly thereafter, and some 50,000 Vietnamese troops and 50,000 Vietnamese workers were sent to Europe. The Vietnamese also endured additional heavy taxes to help pay for France's war efforts. Numerous anticolonial revolts occurred in Vietnam during the war, all easily suppressed by the French. In May 1916, the sixteen-year-old king, Duy Tan, escaped from his palace in order to take part in an uprising of Vietnamese troops. The French were informed of the plan and the leaders arrested and executed. Duy Tan was deposed and exiled to Reunion in the Indian Ocean. One of the most effective uprisings during this period was in the northern Vietnamese province of Thai Nguyen. Some 300 Vietnamese soldiers revolted and released 200 political prisoners, whom, in addition to several hundred local people, they armed. The rebels held the town of Thai Nguyen for several days, hoping for help from Chinese nationalists. None arrived, however, and the French retook the town and hunted down most of the rebels.

In 1917, Phan Boi Chau was released from prison. He spent the next eight years in exile in China, studying and writing but exerting little direct influence on the Vietnamese nationalist movement. In 1925 he was kidnaped by the French in Shanghai and returned to Hanoi, where he was tried and sentenced to hard labor for life. The sentence was later changed to house arrest until his death in 1940. Vietnamese historians view Phan Boi Chau's contribution to the country's independence as immeasurable. He advocated forcibly expelling the French, although he was not able to solve the problems involved in actually doing it. He suggested learning from other Asian independence movements and leaders, while realizing that in the end only the Vietnamese could win their own independence. His greatest weakness, according to many historians, was his failure to involve the Vietnamese peasantry, who composed 80 percent of the population, in his drive for independence. Rather than recruiting support at the village level, Phan Boi Chau and his followers concentrated on recruiting the elite, in the belief that the peasant masses would automatically rally around the scholar-gentry. Future Vietnamese independence leaders took inspiration from the efforts of the early nationalists and learned from their mistakes the importance of winning support at the local level.

An important development in the early part of the twentieth century was the increased use of quoc ngu in the northern part of the country through a proliferation of new journals printed in that script. There had been quoc ngu publications in Cochinchina since 1865, but in 1898 a decree of the colonial government prohibited publication without permission, in the protectorate areas, of periodicals in quoc ngu or Chinese that were not published by a French citizen. In 1913 Nguyen Van Vinh succeeded in publishing Dong Duong Tap Chi (Indochinese Review), a strongly antitraditional but pro- French journal. He also founded a publishing house that translated such Vietnamese classics as the early nineteenth century poem Kim Van Kieu as well as Chinese classics into quoc ngu. Nguyen Van Vinh's publications, while largely pro-Western, were the major impetus for the increasing popularity of quoc ngu in Annam and Tonkin. In 1917 the moderate reformist journalist Pham Quynh began publishing in Hanoi the quoc ngu journal Nam Phong, which addressed the problem of adopting modern Western values without destroying the cultural essence of the Vietnamese nation. By World War I, quoc ngu had become the vehicle for the dissemination of not only Vietnamese, Chinese, and French literary and philosophical classics but also a new body of Vietnamese nationalist literature emphasizing social comment and criticism.

In the years immediately following World War I, the scholar- led Vietnamese independence movement in Cochinchina began a temporary decline as a result, in part, of tighter French control and increased activity by the French-educated Vietnamese elite. The decrease of both French investments in and imports to Vietnam during the war had opened opportunities to entrepreneurial Vietnamese, who began to be active in light industries such as rice milling, printing, and textile weaving. The sale of large tracts of land in the Mekong Delta by the colonial government to speculators at cheap prices resulted in the expansion of the Vietnamese landed aristocracy. These factors in combination led to the rise of a wealthy Vietnamese elite in Cochinchina that was pro-French but was frustrated by its own lack of political power and status.

Prominent among this group was Bui Quang Chieu, a French- trained agricultural engineer, who helped organize the Constitutionalist Party in 1917. Founded with the hope that it would be able to exert pressure on the Colonial Council of Cochinchina, the governing body of the colony, the party drew its support from Vietnamese who were large landowners, wealthy merchants, industrialists, and senior civil servants. The Colonial Council, established in 1880, was controlled by French interests, having only ten Vietnamese members out of twenty-four by 1922. The demands of the party included increased Vietnamese representation on the Colonial Council, higher salaries for Vietnamese officials, replacement of the scholar-official administration system with a mode modern bureaucracy, and reform of the naturalization law to make it easier for Vietnamese to become French citizens.

When the party failed to gain acceptance of any of these demands, it turned to its most pressing economic grievance, the ethnic Chinese domination of the Cochinchinese economy. While French investors exercised almost exclusive control over industry and shared control of agriculture with the Vietnamese, the ethnic Chinese were sought out by the French to act as middlemen and came to dominate rice trade and retail business in both urban and rural areas. A boycott of Chinese goods organized by the party, however, was largely unsuccessful. By the mid 1920s, the Vietnamese entrepreneurial elite and the Constitutionalist Party had grown increasingly critical of the French. However, more progressive groups had displaced them in the Vietnamese nationalist movement.

The mid 1920s brought a period of increased activity among the growing Vietnamese worker class, and pedicab drivers, dye workers, and textile workers launched strikes with some success. In August 1925, workers belonging to an underground union struck at the Ba Son naval arsenal in Saigon-Cholon, ostensibly for higher pay but in actuality to block two French naval ships from being sent to Shanghai to pressure striking Chinese workers. The strikers were successful in their demands and, in November, held massive demonstrations in Saigon to protest the arrest of Phan Boi Chau in Shanghai.
