Three religious streams, one people
One of the most common misunderstandings about the Cham people is treating them as a single religious bloc. In reality, the Cham community in Vietnam, concentrated mainly in Ninh Thuận and Bình Thuận provinces with additional communities in An Giang, Tây Ninh and Ho Chi Minh City, is divided into three clearly distinct religious streams.
Cham Bàlamôn, also known within the community as Cham Ahiêr, is the largest stream in Ninh Thuận and Bình Thuận. Their religion formed through the localization of Brahmanic (Hindu) elements brought in during the era of the ancient Champa kingdom, deeply blended with indigenous folk belief such as the worship of mountain and sea spirits, deified kings, and historical heroes.
Cham Bàni, also called Cham Awal, is a community that adopted Islam centuries ago but localized it so thoroughly that it now retains only certain symbolic elements of Islamic teaching, without observing the full Five Pillars practiced by orthodox Muslim communities. Cham Bàni worship multiple deities, venerating earth spirits, deified kings and ancestors, and while Allah is acknowledged, Allah's place in their spiritual life remains far less central than in orthodox Islamic practice.
Cham Islam, concentrated mainly in An Giang and Tây Ninh, follows Islam in near-complete accordance with orthodox law: five daily prayers, the full Ramadan fast, pilgrimage to Mecca where possible, and wedding and funeral customs distinct from both the Bàlamôn and Bàni communities. Though sharing a common language and the historical legacy of the Champa kingdom, these three communities maintain separate religious lives, calendars and festivals, and should not be conflated when studying Cham culture.
Katê, the great festival of the Cham Bàlamôn
Katê is the largest annual festival of the Cham Bàlamôn community, held on the first day of the seventh month of the Cham calendar, usually falling in late September or early October by the Gregorian calendar. It is an occasion to honor kings, deities and ancestors who contributed to the community, while praying for favorable weather, bountiful harvests, marital harmony and the flourishing of descendants.
The festival typically spans three days, opening with a procession carrying the ceremonial garments of the goddess Po Nagar from the Cham Bàni village of Hữu Đức to the Poklong Garai tower or other temple sites. At the tower, the main rites include opening the tower doors, bathing the deity's statue with sacred water and wine, dressing it in new garments, and holding the main ceremony accompanied by traditional Cham instruments such as the Ginăng drum, the Baranưng drum and the Saranai oboe. After the tower rites, people return to their villages and households to continue honoring ancestors and celebrating, creating an atmosphere resembling a New Year for the Cham Bàlamôn community. The Katê festival in Ninh Thuận and Bình Thuận has been recognized as a National Intangible Cultural Heritage.
Ramưwan, the sacred month of the Cham Bàni
While Katê belongs to the Cham Bàlamôn, the Cham Bàni community has its own most important observance, called Ramưwan, a name derived from Ramadan. Ramưwan does not, however, fully correspond to the Ramadan fast observed by Muslim communities elsewhere in the world. Before religious dignitaries (thầy Char) enter the Bàni house of worship to begin the fasting period, the community carries out rites deeply rooted in indigenous Cham custom, including grave-sweeping, rice offerings to honor ancestors, and worship of goddesses. Ramưwan is thus both a fasting month carrying Islamic coloring and an occasion for family reunion and ancestor remembrance, regarded by the Cham Bàni as one of the most important observances of their year.
The Cham towers: living sites, not ruins
Ancient Cham tower complexes such as Poklong Garai and Po Rome in Ninh Thuận, or Po Sah Inư in Bình Thuận, are often described as remarkable brick architecture of the former Champa kingdom. But for today's Cham Bàlamôn community, these towers are not archaeological ruins; they remain active places of worship, housing statues and altars of deified kings, where religious dignitaries (thầy Cả sư, thầy Bà, thầy Kadhar) perform regular rites, and which serve as the center of the annual Katê festival. Preserving the Cham towers is therefore not simply a matter of architectural conservation, but is bound up with sustaining a religious life that the Cham Bàlamôn community continues to practice today.
