The Sultanate of Mataram was the last major independent Javanese kingdom on the island of Java before it was colonised by the Dutch. It was the dominant political force radiating from the interior of Central Java from the late 16th century until the beginning of the 18th century. Mataram reached its peak of power during the reign of Sultan Agung Anyokrokusumo (r. 1613–1645), and began to decline after his death in 1645. By the mid-18th century, Mataram lost both power and territory to the Dutch East India Company. It had become a vassal state of the company by 1749.
