The foreign culture brought by these traders then underwent a process of adjustment to the local indigenous culture.

The following will describe the historical relics of the Hindu-Buddhist period in various fields, including:

1. Religious Affairs

Before Hindu-Buddhist religion and culture entered the archipelago, people had the belief to worship the spirits of their ancestors called animism and dynamism.

Animism is the belief in objects that are thought to have a soul that inhabits them. While dynamism is a belief that every object has luck or supernatural abilities. danthe elite around the palace was the first group known to have embraced the Hindu-Buddhist religion, from there the wider community began to embrace the religion as well.

2. Politics

The royal system of government was introduced by the Indians. This system is formed from small groups of people who are united with the ownership of a large area. The chief of the tribe who is considered the best and strongest is considered entitled to the royal throne. The leader is then determined based on descent and inheritance rights in accordance with the applicable caste law. From there, the kingdoms as we know it began to emerge, namely Kutai, Tarumanegara, Hindu Mataram, Singosari, and so on.

3. Social Affairs

The entry of Hindu religion and culture brought caste rules that determine class in society, namely: Brahmin caste (priests and scholars), Kshatriya caste (leader of soldiers, nobles, and officials), Vaisya caste (traders, farmers, landowners, and soldiers). , the Sudra caste (the commoners and manual laborers).
