next few centuries. While not much information is available about them, plates and other forms of evidence obtained from the Comilla district indicate that Gopachandra ruled the area in the early 500s. The Khargas became rulers in the next century. They were followed by the Deva dynasty, Harikela kingdom, Chandras and the Varmans. They were based in different sites of the Comilla district and Dhaka district's Vikrampur. Around that time, Bengalis first ruled in Varendra. Gaur was ruled by Sasanka in the early 600s. He was based in Karnasuvarna in modern-day Murshidabad district. Contemporary Chinese reports and coinage suggest that he was a firm Shaivite who was vehemently opposed to Buddhism. Opposition to Buddhism and a commitment to Brahminism apparently continued under the Sura dynasty, founded by Adisura around 700 CE. Around the middle of the eighth century a firm Buddhist, Gopala, assumed power in Bengal, possibly supported by Buddhist chiefs who were opposed to the effects of the Suras and Sasanka's faithful Brahmanism. During this time, the kingdoms of the Bay of Bengal were trading with the nations of nearby South Asia and Southeast Asia, thereby exporting Buddhism into Sri Lanka to the south and both Hinduism and Buddhism into Indonesia, Thailand, Malaysia, Singapore and the Philippines to the east. Gauda Kingdom By the 6th century, the Gupta Empire, which ruled over the northern Indian subcontinent had largely broken up. Eastern Bengal splintered into the kingdoms of Vanga, Samatata and Harikela while the Gauda kings rose in the west with their capital at Karnasuvarna (near modern Murshidabad). Shashanka, a vassal of the last Gupta Emperor proclaimed independence and unified the smaller principalities of Bengal (Gaur, Vanga, Samatata). He vied for regional power with Harshavardhana in northern India after treacherously murdering Harsha's elder brother Rajyavardhana. Harsha's continuous pressure led to the gradual weakening of the Gauda kingdom founded by Shashanka and finally ended with his death. This burst of Bengali power ended with the overthrow of Manava (his son), Bengal descended into a period marked by disunity and intrude once more. Pala dynasty The Pala dynasty ruled Bengal until the middle of the twelfth century and expanded Bengali power to its farthest extent and supported Buddhism. It was the first independent Buddhist dynasty of Bengal. The name Pala ( pal) means protector and was used as an ending to the names of all Pala monarchs. The Palas were followers of
