Srivijaya was an important centre for the expansion of Buddhism from the 7th to 11th century AD. Srivijaya was the first polity to dominate much of western Maritime Southeast Asia. Due to its location, Srivijaya developed complex technology utilizing maritime resources. In addition, its economy became progressively reliant on the booming trade in the region, thus transforming it into a prestige goods-based economy.
