his countrymen from Karnataka into Bengal which explains the southern origin of the Sena Dynasty. Around the 1150s the Palas lost power to the Senas. Chandra dynasty The Chandra dynasty were a family who ruled over the kingdom of Harikela in eastern Bengal (comprising the ancient lands of Harikela, Vanga and Samatata) for roughly a century and a half from the beginning of the 10th century CE. Their empire also encompassed Vanga and Samatata, with Srichandra expanding his domain to include parts of Kamarupa. Their empire was ruled from their capital, Vikrampur (modern Munshiganj) and was powerful enough to militarily withstand the Pala Empire to the north-west. The last ruler of the Chandra Dynasty, Govindachandra, was defeated by the south Indian Emperor Rajendra Chola I of the Chola dynasty in the 11th century.
