Aga Bakar, Mirza  an 18th century Persian noble and zamindar of parganas Buzurg Umedpur and Salimabad constituting major part of modern greater Barisal district. He was the son-in-law of murshid quli khan ii (Rustam Jang). Famous for his firmness and courage, Aga Bakar had an adventurous role in the conflict between Rustam Jang and alivardi khan over the possession of Orissa.

Alivardi became the nawab of Bengal after the fall of sarfaraz khan, but Orissa continued to be held by Rustam Jang. Mirza Bakar accompanied his father-in-law and proceeded towards Balasore from Cuttack to face Alivardi with the object of re-conquering Bengal and encamped at Phulwari (December 1740). The Mirza launched the attack, but was wounded and defeated on 3 March 1741. Rustam Jang fled with the wounded Mirza to Masulipatam. Their family members were saved from being captured by Alivardi's men through the timely aid of a friend of Rustam Jang, who was the zamindar of Khurda. Rustam Jang's general Shah Murad safely conducted them to Mirza Bakar. They had to spend their days in the Deccan in a destitute condition. Alivardi left Orissa for Murshidabad leaving his nephew and son-in-law Sayed Ahmad as naib nazim of Orissa.

After his recovery Mirza Bakar, along with Mir Habib, reached Cuttack with a batch of Maratha infantry in August 1741, held Sayed Ahmad with his family, kept them confined and captured Midnapore and Hijli. Alivardi, hearing of this discomfiture, marched against the Mirza, inflicted a defeat upon him at Raipur on the southern bank of the Mahanadi (December 1741) and compelled him to return to the Deccan with his Maratha allies.

Aga Bakar seems to have surrendered to Alivardi Khan sometime at the beginning of 1742 and was granted a fief in the Buzurg Umedpur and Salimabad parganas which he held till his death in 1754 AD. He established a big ganj (mart) in Buzurg Umedpur, which was named Bakarganj after him. Bakarganj grew up into an important port-town where Persians, Armenians and Kashmiri Khwajas used to trade in salt and hide. Perhaps Aga Bakar controlled his estate through a deputy, himself residing in Dhaka.

Aga Bakar and his son Aga Sadeq appear to have been involved in the palace intrigue in Murshidabad and were in clear alignment with sirajuddaula. nawazish muhammad khan, the naib nazim of Dhaka, had two deputies named Husain Quli Khan and his nephew Husainuddin Khan. Siraj charged Husain Quli and Husainuddin with conspiracy and got Husainuddin murdered through his agent Aga Sadeq in 1754 AD. In retaliation Mirza Ali Naqi, a relation of Husainuddin and the kotwal of Dhaka, raided the residence of Aga Bakar. Aga Sadeq fled by the back door leaving his old father a victim to the infuriated mob (1754).

Aga Bakar lies buried in a tomb to the north of Aga Sadeq Maidan in Dhaka. [Muazzam Hussain Khan]
