Shia Islam in Bangladesh

The oldest Shia imambara in the country was the Bibi Ka Rauza in Farashganj, Dhaka, constructed in 1608 by Amir Khan. The building is not fully extant though.[7] During the reign of emperor Jahangir, a Shi'ite by the name of Ibrahim Khan Fath-i-Jang was given the Subahdari (governorship) of Bengal in 1617 and so he set off for Dhaka, bringing many fellow Shi'ites alongside him.

The Sunni governor of Mughal Bengal Shah Shuja's mother, two wives and teacher were all Shi'ites. So many of Shuja's courtiers were Shia such that a saying became prevalent in Dhaka that Shuja had brought with him 300 Shi'ites whom he got settled in different parts of Bengal. Although a staunch Sunni, his rivals in Delhi even started to spread rumours that Shuja had converted to Shi'ism. It was during his term in 1642, that the naval chief Sayyid Murad constructed the Hussaini Dalan in Dhaka.

The next governor of Mughal Bengal, Mir Jumla II also belonged to Shia faith

Mir Sayyid Shakrullah al-Husayni of Najaf was one of the Shia noblemen brought by Shuja, and he was the ancestor of Nawab Sayyid Chottan Saheb, who had a large estate in Abul Hasnat Road in Dhaka. The estate contains the Mohammadi Begum Imambara, which was built in 1707.[8]

From 1717 until 1880, three successive Nawab dynasties – the Nasiri, Afshar and Najafi – ruled over Bengal, and all belonged to the Shia faith.[9]

Murshid Quli Khan was originally born into a poor Deccani Hindu family, before being sold into slavery and bought by Haji Shafi, a Persian merchant from Isfahan who had converted him to Shia Islam. He later worked his way up, eventually becoming the first of the Nawabs of Bengal and founding the Nasiri dynasty. He transferred Bengal's capital from Jahangirnagar (Dhaka) to Murshidabad in present-day India.

The second dynasty, the Afshar, ruled from 1740 to 1757 and was founded by the Shia-born Alivardi Khan. Siraj ud-Daulah, the last of the Ashfar and the most well-known of the Nawabs, was killed in the Battle of Plassey in 1757 by the British East India Company.[10] He was succeeded by Shia-born Mir Jafar who founded the third and final Nawab dynasty of Bengal, the Najafi.[11]

Mir Ashraf Ali (d. 1829), a devout Shi'ite from Shiraz, migrated to Dhaka in the 18th century, where, he gained prominence as a landlord and courtier to the Naib Nazims of Dhaka. With properties spreading across Dhaka, Comilla, Barisal, Mymensingh and Chittagong; Ali became the wealthiest person in eastern Bengal in his time, with hundreds of employed farmers and numerous charitable donations towards the city of Dhaka. In response to Shah Abdul Aziz's famous criticism on the Twelver ideology, Ali sent a large sum of money to Iraq in return for a response to the criticism by the senior Shi'ite clerics there. It is unknown whether a response was given.[12]

In 1799, Agha Muhammad Reza, a Mughal Shia nobleman in Sylhet of Iranian origin rebelled against the East India Company. Gaining support from thousands of peasants after claiming to be a Sufi saint, Reza successfully invaded the nearby Kachari Kingdom. Later proclaiming himself as the Mahdi (promised messiah) and twelfth imam, he was captured and imprisoned in Calcutta.[13][14]

In 1861, the Bibi Ka Rauza Imambara in Farashganj, Dhaka was renovated by RM Doshanji. In the 19th century, descendants of the Shia zamindar family of Sitalpur in Purnia, Bihar migrated to the village of Sindurna in Thakurgaon in modern-day Bangladesh. Shaykh Muhammad Raj of this family built the Shalbari Mosque for the Shia community in the village in 1888, and the site remains a popular tourist attraction.[6] In 1891, the Mir Yaqub Imambara was constructed in 1 Hussaini Dalan Road, Dhaka. It was refurbished in 2004 by the Shia Anjuman-e-Husayni.
