The army and navy fought numerous wars and for defending their kingdom against the Chinese, Khmer, and Vietnamese empires, and also thwart piracy, especially Chinese and Malay pirates. The Champa military was known for its skill and innovation in warfare, particularly in shipbuilding and naval warfare. The Champa Kingdom was located in a strategic position on the coast, which allowed them to develop a strong navy and engage in maritime trade with other kingdoms in the region.

The Champa army used cavalry and elephants in battle, which were intended to charge enemy lines and break their formations. The soldiers were armed with a variety of weapons, including swords, spears, and bows and arrows. They were also skilled in the use of siege weapons and were known to use catapults and other devices to breach enemy defenses.

The Champa navy used advanced shipbuilding techniques and innovative approach to naval warfare. The navy was composed of large warships that were crewed by skilled sailors and soldiers. The Champa navy was known for its use of fire ships, and trebuchets, which were used to launch projectiles at enemy vessels.

However, despite their regional and naval power, the Khmer and Dai Viet empires eventually defeated the Chams. After several wars, the Khmer Empire conquered Champa in the 12th century, and the Dai Viet Empire conquered Champa in the 15th century. The Chams were eventually assimilated into the Vietnamese culture, and their naval power declined. However, their legacy as skilled seafarers and shipbuilders has endured. The Champa Kingdom's military legacy continues to be felt today and is a testament to their skill and ingenuity in the field of military technology.

History The Kingdom of Champa was founded in the second century, and the kingdom faced threats from neighboring kingdoms. The Champa military was founded as a means of protecting the kingdom's borders and maintaining its independence. According to legends and oral traditions, the Champa military was initially composed of small groups of warriors who were organized into local militias. These militias were responsible for defending their local communities and were led by local leaders who were appointed by the king. As the kingdom grew and faced increasing external threats, the Champa military became more organized and centralized.

These civil wars were typically fought between rival factions or claimants to the throne, and were often sparked by political or economic grievances, and were fought between rival factions or claimants to the throne. Despite the conflicts, the Champa kingdom was able to survive for many centuries, and its legacy continues to be felt today.

The first Champa Civil War took place in the early 6th century, when a prince named Fan Hsiung rebelled against his father, the king of Champa. The rebellion was successful, and Fan Hsiung established himself as the new king of Champa.

In the 8th century, another civil war broke out between two Champa princes who were vying for the throne. The conflict lasted for several years and resulted in the weakening of the Champa kingdom.

In the 10th century, a Champa king named Jaya Simhavarman III was overthrown by a rival claimant to the throne, who established himself as the new king of Champa. The conflict resulted in the splitting of the Champa kingdom into two separate states, with one based in the north and the other based in the south.

Sino-Cham Wars The Sino-Cham Wars were a series of conflicts that took place between the Chinese and Champa kingdoms during the Tang dynasty in the 7th and 8th centuries. The wars were fought over control of the lucrative trade routes that passed through the region, particularly the maritime trade routes that linked China with Southeast Asia and the Indian Ocean.

The first Sino-Cham War began in 602 AD, when the Chinese emperor launched a naval expedition to the Champa kingdom in retaliation for Champa's support of a rebellion in Chinese-held Vietnam. The Chinese were able to capture several Champa cities and establish garrisons in the region, but were eventually forced to withdraw due to logistical difficulties.

The second Sino-Cham War began in 753 AD, when the Chinese launched another naval expedition to the Champa kingdom in response to Champa's attacks on Chinese merchant ships. The Chinese were able to capture several Champa cities and establish garrisons in the region, but were again forced to withdraw due to logistical difficulties and the outbreak of disease among their troops.

The Chinese were able to establish a presence in the region and secure their control over the trade routes, while the Champa kingdom was weakened by the conflicts and faced increasing pressure from neighboring kingdoms. However, the wars also led to the exchange of cultural and technological ideas between the two kingdoms, particularly in the areas of shipbuilding and naval warfare.

Khmer–Cham wars

The Khmer-Cham Wars were a series of conflicts that took place between the Khmer Empire and the Champa Kingdom during the 9th to 15th centuries. The wars were fought over control of the Mekong Delta region, which was a strategic area for trade and agriculture.

However, the Champa kingdom was able to regain its independence and launch counter-attacks against the Khmer Empire in the following centuries.

Trinh-Nguyen War During the Trinh-Nguyen War where the Le Dynasty was facing political instability between two powerful military families, Champa came under suzerainty by the Nguyen Lords in 1611. They revolted against the Nguyen dictatorship six times throughout but lost more territory to them.

Tây Sơn wars During the Tây Sơn wars, the rebellion thrusted the Nguyen Lords out of power. However, Champa was again torn by civil war between those who supported the Tay Son Dynasty led by Po Tisuntiraidapuran and those who supported the Nguyen Lords led by Po Krei Brei and Po Ladhuanpuguh. Eventually Po Tisuntiraidapuran was captured and executed, allowing the Pro-Nguyen Cham co-rulers to have Champa side with them turning the tide of the war against the rebellion paving the way to the Nguyen Dynasty.

Conflict with the Europeans Champa helped Cambodia during the Cambodian–Spanish War, which resulted in delivering a fiasco to the Spanish conquistadors. Governor of Manila, Luis Pérez Dasmariñas (fl. 1593–96) sent a letter to the court of king Philip II in late 1595, antagonizing the Cham king as "a vicious dangerous tyrant who was treacherous and full of evil deeds," while his second letter suggested that just around 200–300 Spanish soldiers and 500 local mercenaries would be needed to conquer Champa. During that time, the Cham were remembered by Spanish, Portuguese, and Dutch merchants and seamen as ferocious pirates of the South China Sea who numerously boarded merchant ships, plundering cargos, kidnapping crew members, and routinely took European hostages to slavery. Cham kings were described to be at least involved or actively encouraging raids against foreign ships.

Rebellions During the Nguyen Dynasty, Minh Mạng succeeded his father and enacted repressive acts against ethnic minorities, predominantly the Chams and the Montagnards. He repressed their freedom of religion banning Hinduism, Islam, and Christianity forcing them to assimilate to Vietnamese culture, and allowed Vietnamese settlers to expropriate their land. This incited armed uprisings against him and any Pro-Viet Cham official.

Ja Lidong rebellion In August 1822, Ja Lidong from Malathit (southwest of Phan Thiết) led a Cham uprising against Minh Mang's harsh mandatory levies and were advancing toward Bình Thuận, posing a threat to densely populated areas of Bình Thuận where the (Vietnamese) Kinh were majority residents. Furious with news of the rebellion, Po Klan Thu requested Minh Mang for help, and Minh Mang immediately approved. Po Klan Thu was enthroned shortly after as ruler of Champa but a "commissioner of Champa" from the eyes of the Vietnamese, still he wasn't able to restrain discontent among the Chams. After receiving the investiture, Po Klan Thu returned to Panduranga's capital Phan Rí, while Ja Lidong's forces had captured many regions and blown up a strategic fort in Thị Linh.
