Ancient Kingdoms:
The history of Indonesia is marked by the rise and fall of several powerful maritime kingdoms, including Srivijaya and Majapahit.

The Srivijaya Empire, based on the island of Sumatra, controlled maritime trade routes in Southeast Asia during the 7th to 13th centuries.
Colonial Era:

In the subsequent decades, Indonesia experienced periods of political instability, economic growth, and social change.
