Chams in the context of "Matriarchy"

The Vietnamese people (Vietnamese: người Việt, lit. 'Việt people') or the Kinh people (Vietnamese: người Kinh, lit. 'Metropolitan people'), also known as the Viet people or the Viets, are a Southeast Asian ethnic group native to modern-day northern Vietnam and southern China who speak Vietnamese, the most widely spoken Austroasiatic language.

Vietnamese Kinh people account for 85.32% of the population of Vietnam in the 2019 census, and are officially designated and recognized as the Kinh people (người Kinh) to distinguish them from the other minority groups residing in the country such as the Hmong, Cham, or Mường. The Vietnamese are one of the four main groups of Vietic speakers in Vietnam, the others being the Mường, Thổ, and Chứt people. Diasporic descendants of the Vietnamese in China, known as the Gin people, are one of 56 ethnic groups officially recognized by the People's Republic of China, residing in the Guangxi Zhuang Autonomous Region.

Nam tiến (Vietnamese: [nam tǐən]; chữ Hán: 南進; lit. "southward advance" or "march to the south") is a historiographical concept that describes the historic southward expansion of the territory of Vietnamese dynasties' dominions and ethnic Kinh people (Đại Việt) from the 11th to the 19th centuries. The concept of Nam tiến has differing interpretations, with some equating it to Vietnamese colonization of the south and to a series of wars and conflicts between several Vietnamese dynasties and Champa Kingdoms, which resulted in the annexation and Vietnamization of the former Cham states as well as indigenous territories. The nam tiến became one of the dominant themes of the narrative that Vietnamese nationalists created in the 20th century, alongside an emphasis on non-Chinese origin and Vietnamese homogeneity. Within Vietnamese nationalism and Greater Vietnam ideology, it served as a romanticized conceptualization of the Vietnamese identity, especially in South Vietnam and modern Vietnam.

The Vietnamese domain gradually expanded from its original heartland in the Red River Delta into southern territories, which were controlled by the Champa kingdoms. In a span of some 700 years, the Vietnamese domain tripled the area of its territory and more or less acquired the elongated shape of modern-day Vietnam. Beginning in the 20th century, modern Vietnamese historiography, under the auspices of nationalism and racialism, coined the term Nam tiến for what they believed to be a gradual, inevitable southern expansion of Vietnamese domains. According to the 20th-century Vietnamese scholars who constructed the Nam tiến as a continuous historical phenomenon, the 11th to the 14th centuries saw battle gains and losses as frontier territory changed hands between the Viet and the Chams during the early Cham–Viet wars. In the 15th, 16th and 17th centuries, following the Fourth Chinese domination of Vietnam (1407–1427), the Vietnamese defeated the less centralized state of Champa and seized its capital in the 1471 Cham–Vietnamese War. From the 17th to the 19th centuries, Vietnamese settlers penetrated the Mekong Delta. The Nguyễn lords of Huế wrested the southernmost territory from Cambodia by diplomacy and by force, which completed the "March to the South".

Champa (Cham: ꨌꩌꨛꨩ, چمڤا; Khmer: ចាម្ប៉ា; Vietnamese: Chiêm Thành 占城 or Chiêm Bà 占婆; modern Vietnamese Chăm Pa) was a collection of independent Cham polities that extended across the coast of what is present-day central and southern Vietnam from approximately the 2nd century AD until 1832.

According to earliest historical references found in ancient sources, the first Cham polities were established around the 2nd to 3rd centuries AD, in the wake of Khu Liên's rebellion against the rule of China's Eastern Han dynasty, and lasted until when the final remaining principality of Champa was annexed by Emperor Minh Mạng of the Vietnamese Nguyễn dynasty as part of the expansionist Nam tiến policy. The kingdom was known variously as Nagaracampa (Sanskrit: नगरचम्प), Champa (ꨌꩌꨛꨩ) in modern Cham, and Châmpa (ចាម្ប៉ា) in the Khmer inscriptions, Chiêm Thành in Vietnamese, Campa in Malay, Zhànchéng (Mandarin: 占城) in Chinese records, and al-Ṣanf (Arabic: صَنْف) in Middle Eastern Muslim records.
