History.
The history of Bandar spans several centuries, and it became a principal port ("bandar") not far from the medieval capitals of Sonargaon and Jahangirnagar. In 1481 AD, the Bandar Shahi Mosque was constructed which became a focal point for Islam in Bandar. A Muslim preacher and Bengal Sultanate officer by the name of Haji Baba Saleh migrated to a village in Bandar where he invited the locals to Islam. The village then came to be known as Salehnagar, or the "city of Saleh". A mosque and mazar (mausoleum) was later built and named after him in 1504 AD. 
After the fall of the Bengal Sultanate in the late sixteenth century, independent chieftains formed a confederacy known as the Baro-Bhuiyans to defend Bengal from Mughal integration. Numerous battles were fought in Bandar between the Mughal forces and Baro-Bhuiyans such as Musa Khan, Dawud Khan, Abdullah Khan and others. Musa's grandson, Dewan Munawwar Khan, later moved his residence to what came to be known as Dewanbagh (or Munawwar Khan Bagh) in Bandar, where he also built the Qadam Rasul monument and was buried east of the historic Dewanbagh Mosque. Historians suggest that the Sonakanda Fort in Bandar was built by Mughal governor Mir Jumla II to protect against pirates.
Bandar was established as a thana in 1964. During the Bangladesh Liberation War of 1971, a mass killing was conducted in Sirajdoullah Club playground leading to the death of 54 people on 3 April. On 22 November, a brawl took place between the Pakistan Army and the Bengali freedom fighters at the banks of the Shitalakshya in Dhamgar. Another battle took place 5 days later in which a Pakistan Army gunboat was destroyed and numerous Pakistan Army soldiers killed. Defeated again on 12 December, the Pakistan Army fled to the western side of the Shitalakshya. A direct encounter took place in Bandar Railway Station where many soldiers were killed or wounded and were forced to surrender. Bandar Thana became liberated on 15 December. In 1993, Bandar Thana's status was upgraded to upazila.
