The worship of Hung Kings originates from Hung Kings dynasty in the belief that all Vietnamese people have the same origin “Dragon’s children and Fairy’s grand-children”; and also expresses Vietnamese philosophy “When drinking water, remember the source” and the spirit of great national unity.
According to legend, Lac Long Quan – son of Kinh Duong Vuong Loc Tuc got married with Au Co – daughter of King De Lai and gave birth to 100 sons. After that, 50 sons followed Au Co and 50 others followed Lac Long Quan to settle. The first son followed his mother to arrived in Phong Chau Land (now Phu Tho Province) and established Van Lang Nation and became King Hung.
Van Lang was the first nation in Vietnamese history and ruled by 18 kings. Hung Kings taught local people to grow rice and selected Nghia Linh Mountain, the highest mountain in the region to perform the religious rituals of the agricultural population as worship of rice god and sun god for the good weather, good crops.
To remember the great merit of Hung Kings, the people set up the temple (Hung Kings Temple Relic Site) at the center of Nghia Linh Mountain and chose the 10th day of the third lunar month as Ancestral Anniversary day. From this first temple, the worship of Hung Kings has gradually spread and reaches a national level, and now it is practiced at temples in Northern, Central and Southern and also by Vietnamese overseas.
According to historical documents, the worship of Hung Kings has strongly developed for a long time before officially honored in Le Dynasty (1428 – 1788). It was acknowledged by the imperial dynasties of the Le (1428–1788), Tay Son (1778–1802), and Nguyen (1802–1945) by means of codified legends, royal conferment, and provision of lands to support the worship.
Today the Government allocates a substantial budget to safeguard, restore and maintain the spaces of the worship of Hung Kings, especially at Hung Kings Temple Relic Site, and supports the efforts of local people with a role in the Hung Kings Ancestral Anniversary, publishing items (books and DVDs) on legends, rituals and the folk arts related to the worship to serve communities.
There are also initiatives to include Hung Kings legend materials in the school curriculum in order transmit the tradition to future generations. The Government also approved a public holiday on the 10th day of the third lunar month so that people nationwide participate and organize sacrificial activities. The total number of Hung Kings temples nationwide is 1,417.
