Srivijaya (Indonesian: Sriwijaya), 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 AD. 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.
The earliest reference to it dates from the 7th century. A Tang dynasty Chinese monk, Yijing, wrote that he visited Srivijaya in 671 for six months. The earliest known inscription in which the name Srivijaya appears also dates from the 7th century in the Kedukan Bukit inscription found near Palembang, Sumatra, dated 16 June 682. Between the late 7th and early 11th century, Srivijaya rose to become a hegemon in Southeast Asia. It was involved in close interactions, often rivalries, with the neighbouring Mataram Kingdom, Khmer Empire and Champa. Srivijaya's main foreign interest was nurturing lucrative trade agreements with China which lasted from the Tang to the Song dynasty. Srivijaya had religious, cultural and trade links with the Buddhist Pala of Bengal, as well as with the Islamic Caliphate in the Middle East.
