Fan Hu Ta takes the throne of Champa and the regnal name Bhadravarman I in 380.

Also in this year, the King moves the capital to Indrapura in Quang Nam.

Fan Yang Mai, following years of internal trouble, overthrows the previous dynasty and seizes the Cham throne in 421.

Fan Yang Mai I, king of Champa, commands over one hundred boats in a looting expedition along Jih-nan’s coast in Chinese-held Tonkin.

In his absence, the Chinese retaliate by laying siege to Ch'u-su, breaking it only after severe weather compels them to withdraw.

Yang Mai’s troops, while fighting in Tonkin, attempt, unsuccessfully, to enlist the aid of Funan soldiers.

Skirmishing continues sporadically between the Chinese and the Chams until 425, when Tonkin’s new governor denounces the ongoing peace talks and lays siege to Ch'u-su, eventually reducing the city and carrying off large quantities of plunder.

His forces then advance on the Cham capital near present Hue, commandeering Champa’s gold, and taking control of the country, forcing the Cham people to pay an annual tribute.

Cham leader Rudravarman I is granted investiture by China as the first king of the fourth dynasty of Champa.

Cham king Sambhuvarman, seeing an opportunity in the anarchic conditions obtaining under China’s new Sui dynasty, ends Champa’s subjugation to the Chinese, but, when confronted by the newly vigorous empire and its soldiers, renews tribute payments to the empire.

Cham king Sambhuvarman, seeing an opportunity in the anarchic conditions obtaining under China’s new Sui dynasty, ends Champa’s subjugation to the Chinese, but, when confronted by the newly vigorous empire and its soldiers, renews tribute payments to the empire in 595.

King Indravarman II of Champa, a country located in the central region of what is now Vietnam, founds a new dynasty at Indrapura (Quang Nam).

He initiates a building program featuring the Dong Duong Style of Cham art.

Cham King Jaya Indravarman, on hearing in 1103 from a Vietnamese refugee that he could easily reconquer the three northern provinces lost to Dai Viet in the Vietnamese-Cham War of 1068-74, immediately ceases his customary tribute payments to his neighbor and launches an attack on the ceded territories.

At first successful, the Cham forces are unable to hold the provinces beyond a few months before the Dai Viet forces defeat them and drive them back into Champa proper.

Che Anan’s insurgent Cham forces, aided by the Mongols, finally defeat their Vietnamese overlords in 1326, ending Champa’s forces vassalage to Dai Viet.

Che Anan becomes king of Champa, and peace obtains between the two nations.

French gunships under Charles Rigault de Genouilly attack the port of Da Nang in 1858 under the orders of Napoleon III of France, causing significant damages yet failing to gain any foothold.

De Genouilly decides to sail south.

Nguyen Anh—the Vietnamese emperor Gia Long—had tolerated Catholicism and employed some Europeans in his court as advisors after establishing the Nguyen Dynasty in 1802.

However, he and his successors have been conservative Confucians who have resisted Westernization.

The next Nguyen emperors, Ming Mang, Thieu Tri, and Tu Duc, had brutally suppressed Catholicism and pursued a "closed door" policy, perceiving the Westerners as a threat.

Tens of thousands of Vietnamese and foreign-born Christians were persecuted and trade with the West slowed during this period.

These acts were soon being used as excuses for France to invade Vietnam.

The early Nguyen Dynasty had actually accomplished almost everything the previous great Vietnamese dynasties did (like building roads, digging canals, issuing legal code, holding examinations, sponsoring caring facilities for the sick, compiling maps and history books, exerting influence over Cambodia and Laos, etc.), except that these feats are not enough in the new age of science, technology, industrialization, and international trade and politics. (The Nguyen Dynasty is usually blamed for failing to modernize the country in time to prevent French colonization in late nineteenth century.)
