What are the structure of pre-spanish government?

Pre-Spanish governments in the Philippines varied depending on the region and the time period. However, some common features include:

* Barangay: The barangay was the basic political unit in pre-Spanish Philippines. It was a village or settlement headed by a chieftain or datu. Barangays were often self-sufficient and had their own laws and customs.

* Datu: The datu was the leader of a barangay. Datus were chosen for their strength, wisdom, and leadership skills. They were responsible for protecting their barangay from enemies, settling disputes, and making decisions about the use of land and resources.

* Council of elders: In many barangays, the datu was assisted by a council of elders. The council of elders was made up of respected members of the community who helped the datu make decisions.

* Tribal alliance: Sometimes, barangays would form alliances with each other for protection or to wage war. Tribal alliances were often led by a powerful datu who was recognized as the chief of all the allied barangays.

* Sultanate: In some areas of the Philippines, especially in Mindanao, there were sultanates. Sultanates were larger political units than barangays and were headed by a sultan. Sultans had absolute power and were considered to be religious and political leaders.

The pre-Spanish governments in the Philippines were complex and varied and they played an important role in the development of Philippine society and culture.
