The dialect differs from Standard Urdu as it takes a number of loanwords from the Bengali language, which the dialect's source of origin is geographically surrounded by. The intonations and tone of the language is also shifted closer to Bengali than Standard Urdu. It is described to be a fairly simpler language than Standard Urdu.
History
During the Mughal era, the Bengal Subah was famed for being the wealthiest and industrially the most developed place in the world and having waved the proto-industrialization, its economy showed signs of Industrial revolution. The city of Jahangirnagar was the province's capital in the mid-eighteenth century, and Urdu-speaking merchants from North India started pouring in. Eventually residing in Dhaka, interactions and relationships with their Bengali counterparts led to the birth of a new Bengali-influenced dialect of Urdu. The descendants of these settlers came to be known as Khusbas which meant the happily settled. The Bais and Bara panchayets, as well as the Nawabs of Dhaka, used to converse in this language. Their Urdu language also influenced the language of the Bengali Muslims in Old Dhaka which came to be known as the Dhakaiya Kutti language. Shortly after the Bengali Language Movement of 1952, Urdu culture decreased significantly with many Urdu-speaking families switching to speaking Bengali to avoid controversy. During the Bangladesh Liberation War of 1971, a number of Urdu-speaking families subsequently migrated to Pakistan. As a result, the use of Urdu has become very limited to a few families and a community south of the Dhaka railway line. Described as a wealthy but very closed-off community, the speakers of the dialect honour the Dhakaiya Urdu poets of the past in their own private mushairas. Other modern examples of usage include the University of Dhaka's dwindling Urdu department as well as the Urdu sermons and Islamic lectures given in Dhaka.
Literature and media
The late 18th-century in Dhaka hosted the migration of Mirza Jan Tapish and other Urdu poets from Delhi migrating to the urban hub after an invitation from Shams ad-Daulah, the Naib Nazim of Dhaka. Poetry and literature in Urdu grew popularity in Dhaka with the presence of organisations such as the Anjuman-i Taraqqi-i Urdu and the patronising of it by Dhaka's Nawabs, Sardars and Zamindars such as Khwaja Abdul Ghani and Mir Ashraf Ali. The 19th-century poet Mirza Ghalib of Agra was a close friend of Dhaka's poet Khwaja Haider Jan Shayek. The collaboration between Ghalib and Shayek was collected and compiled by Hakim Habibur Rahman, a later Urdu poet of Dhaka, in his book Inshaye Shayek. Habibur Rahman was a prominent Dhakaiya physician and litterateur whose most famous books include Asudegan-e-Dhaka and Dhaka Panchas Baras Pahle. He was the editor of Bengal's first Urdu magazine, Al-Mashriq in 1906. He later collaborated with Khwaja Adil in 1924 to found another monthly journal called Jadu. His works are celebrated for preserving Urdu, Persian and Arabic literature, compiling them into his Thulatha Ghusala. The language flourished in the media during the 20th century cinema. Khurshid Alam and Sabina Yasmin sang a song, Matiya Hamar Naam, in this dialect for the Bangladeshi filmJibon Niye Jua which released in 1975 after the Independence of Bangladesh.
