whom were consumed by the Naga queen of an earlier king on the night following their election. Gopal, however managed to kill the queen and remained on the throne. The historical evidence indicates that Gopala was not elected directly by his citizens, but by a group of feudal chieftains. Such elections were quite common in contemporary societies of the region. Gopala's ascension was a significant political event as the several independent chiefs recognised his political authority without any struggle. Imperial expansion and consolidation Gopala's empire was greatly expanded by his son Dharmapala and his grandson Devapala. Dharmapala was initially defeated by the Pratihara ruler Vatsaraja. Later, the Rashtrakuta king Dhruva defeated both Dharmapala and Vatsaraja. After Dhruva left for the Deccan region, Dharmapala built a mighty empire in the northern India. He defeated Indrayudha of Kannauj, and installed his own nominee Chakrayudha on the throne of Kannauj. Several other smaller states in North India also acknowledged his suzerainty, as far as Jalandhara. Soon, his expansion was checked by Vatsaraja's son Nagabhata II, who conquered Kannauj and drove away Chakrayudha. Nagabhata II then advanced up to Munger and defeated Dharmapala in a pitched battle. Dharmapala was forced to surrender and to seek alliance with the Rashtrakuta emperor Govinda III, who then intervened by invading northern India and defeating Nagabhata II. The Rashtrakuta records show that both Chakrayudha and Dharmapala recognised the Rashtrakuta suzerainty. In practice, Dharmapala gained control over North India after Govinda III left for the Deccan. He adopted the title Paramesvara Paramabhattaraka Maharajadhiraja. Dharmapala was succeeded by his son Devapala, who is regarded as the most powerful Pala Emperor. His expeditions resulted in the invasion of Pragjyotisha (present-day Assam) where the king submitted without giving a fight and the Utkala (present-day Northern Odisha) whose king fled from his capital city. The inscriptions of his successors also claim several other territorial conquests by him, but these are possibly exaggerated (see the Geography section below). His oldest son, Rajyapala predeceased him, and as so Mahendrapala, his next older son succeeded him. He possibly maintained his father's vast territories and carried out further campaigns against the Utkalas and the Hunas. He passed his empire intact to his younger brother Shurapala I, who held sway over a considerably large territory encompassing Bengal, Bihar and Uttar Pradesh, proven by his Mirzapur copperplate. What happened in Gopala II's rule, the son of Surapala I, is
