Srivijaya, also spelled Sri Vijaya or Sriwijaya, was a Malay thalassocratic empire based on the island of Sumatra (in modern-day Indonesia) that influenced much of Southeast Asia. Srivijaya was an important centre for the expansion of Buddhism from the 7th to 11th century. Srivijaya was the first polity to dominate much of western Maritime Southeast Asia. Due to its location, Srivijaya developed complex technology using 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.
