Srivijaya was a Malay Buddhist thalassocratic empire based on the island of Sumatra, which influenced much of Southeast Asia. Srivijaya was an important centre for the expansion of Buddhism from the 7th to the 12th century AD. Srivijaya was the first unified kingdom to dominate much of the Malay Archipelago. The rise of the Srivijayan Empire was parallel to the end of the Malay sea-faring period. Due to its location, this once-powerful state 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.
The earliest reference to it dates from the 7th century. A Tang dynasty Chinese monk, Yijing, wrote that he visited Srivijaya in year 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 Java, Khmer and Champa.
