Cham-Quenminese War of 1274
The Cham-Quenminese War of 1274, also known as the Second Cham-Kiếm Hoà War, was a military conflict between Chamia and the Kiếm Hoà Dynasty. The conflict was instigated by attempted Chamian expansions further north and west into the dynasty's territories, with Kiều Thạc Nhu immediately retaliating. The conflict existed for approximately four months, from 6 May to 20 August.
The current Chamian king Jaya Vikrantavarman II desired to defy the stipulations laid out by the Treaty of Visrayan, which he saw as detrimental to the Kingdom's sovereign power and economic prosperity. On 6 May, the Chamian armies lead by generals Indrapramati, Vrisaparvan and Pratibahu invaded lands consisting of the present-day Hoang Thái, Vũ Bá and Cao Lãnh provinces, respectively. Receiving news of the incursions, Nhu marched south to drive back Vrisaparvan and Pratibahu, leaving one of her generals Ngô Bạch Xí to deal with Indrapramati. Facing the superior military ability of Nhu, Vrisaparvan and Pratibahu retreated eastward to their kingdom, resulting in Nhu regaining lands conquered by them by mid-July. On the other hand, Xí initially faced struggles encountering Indrapramati, but was able to rejuvenate and push him back across the My Hoa Strait at the end of July. In August, Nhu ordered all armies to push towards the Chamian capital Panduranga, and authorized the ransacking of any major settlement they reach. In 20 August, Nhu faced Vikrantavarman in the Battle of Gopalpathar where she won a decisive victory. Rather than continue fighting and let his capital fall, Vikrantavarman declared his surrender the day after, which was then formalized in the Treaty of Piriyavayoor.
The dynasty's victory in the conflict left Nhu to vassalize the Kingdom, opening the opportunity for her and her successors to raise troops for the dynasty's future conflicts. Moreover, the Treaty demanded that the Kingdom pay a war indemnity totaling Ѧ9.76 billion in today's currency.
