(1) The History of Bhulua- The kingdom of Bhulua was ruled by Kayastha Sur kings, the descendants of Adisur. Its capital was kalyanpur and its patron deity was Varahi. Biswambhar Sur was the founder of this dynasty and he was succeeded by 2. Ganapati 3. Surananda 4. Debananda 5. Madhab Chandra 6. Rajballav 7. Lakhsman Manikya. Lakshman Manikya was the last independent king of this dynasty. The kingdom had rivals like the Portuguese, the Maghs, the Tripura Rajas, Chandradweep kings and the Muslims. The father of Lakshman Manikya gave parts of his kingdom to his two powerful generals in exchange of military help against the Magh Pirates. The Magh Pirates always disturbed the local Hindu population, and if they walked through anyone's residence or touched anyone, that person with his family was declared "fallen" by the Hindu society. Due to the fear of the Maghs of Arakan, the Hindus always resided in safe quarters, and it was due to their disturbances that the population of lower Bengal, including deltoid region and Sundarbans, decreased after 15th Century. During the 16th Century, Bhulua covered the Greater Noakhali district, washed by Meghna River and it controlled some important routes. This resulted in its rivalry with Chandradweep and was ultimately conquered by Ramchandra. Lakshman Manikya was captured and killed. His son Ananta Manikya unsuccessfully fought the Mughals for sometime and then fled to Arakan after his defeat in 1611 A.D. With Ananta Manikya, the royal line of Sur kings came to an end.
(2) King Lakhsman Manikya of Bhulua and his rivalry- Lakshman Manikya was famous for his bravery and knowledge. He was the author of two Sanskrit plays. These are, Vikhyata-vijay, based on the battle of Karna and Arjuna as related in the Mahabharata and Kuvalayasva-charita, based on the story of Madalasa and Kuvalayasva as related in the Mahabharata. His rivalry with Kandarpanarayan of Chandradweep and his son Ramchandra are still famous in folktales. The rivalry grew due to border disputes and due to a Tantrik Brahman named Digvijay Bhattacharya who was the kulaguru of Chandradweep Basu Dynasty.
(3) Digvijay Bhattacharya and Bhuluai Loot- The father of Digvijay Bhattacharya was a Tantrik Brahman from Srihatta and his disciple was king Lakshman Manikya. They later settled in khapura village, within the borders of Chandradweep and the Basu kings of Chandradweep accepted them as kulagurus. But as Digvijay Bhattacharya was also respected by Lakshman Manikya, so the Manikya wanted him to settle in Bhulua. This resulted in a bitter rivalry between two kingdoms. One night the Bhulua king surrounded khapura village with 5000 men, then within Ramchandra's territory and carried off Digvijay's family and other people forcefully to Bhulua. This came to be known as Bhuluai Loot. The surrounded villagers informed Ramchandra about this. The enraged king sent a letter to Manikya asking him to return his kulaguru. Manikya replied-"balak rajar eto spardha bhalo noy" ( The boy king must not be so ambitious ).
(4) Ramchandra marched towards Bhulua- Ramchandra declared in royal court-"Now Lakhsman Manikya will witness the power of boy-king". He ordered generals Rammohan Mal, Rameshwar Dutta, Bhagavan Das, Madan Singha, Garie and Fernandes to march. Among five divisions of army, one division was left to protect the capital Madhabpasha, other 1 div of Bengali army, 1 div buxari, and 2 div Portuguese-4 divs were ordered to march. They crossed kalijira river and surrounded bhulua at night.
(5) Defeat and Capture of Lakhsman Manikya- Lakhsman Manikya was astonished by sound of cannons from battleships at night. He fought bravely next morning but was captured by Rammohan Mal who tied him with iron chains and led to royal ship. Bhulua army fled in confusion. Ramchandra became victorious. Accompanied by Rameshwar Dutta and Bhagwan Das, he returned to Madhabpasha. The rest of the army and navy under Fernandes, Garie and Madan Singha was left to follow.
(6) Trail and Execution- A special court was summoned at Madhabpasha. It gave verdict that Bhulua king should be hanged. But Ramchandra's mother advised him not to do so. Hence manikya was imprisoned. Once king ramchandra was messaging oil before bath and talking with others, Bhulua king was brought before him on his mother's advice. The bhulua king put weight on a coconut tree and it fell near ramchandra. Seeing this his mother ordered the guards to kill manikya. The guards beheaded him.
