Dhaka, formerly known as Dacca, is the capital and largest city of Bangladesh. It is the ninth-largest and seventh-most densely populated city in the world. Dhaka is a megacity, and has a population of 10.2 million residents as of 2022, and a population of over 22.4 million residents in Dhaka Metropolitan Area. It is widely considered to be the most densely populated built-up urban area in the world. Dhaka is the most important cultural, economic, and scientific hub of Eastern South Asia, as well as a major Muslim-majority city. Dhaka ranks third in South Asia and 39th in the world in terms of GDP. Lying on the Ganges Delta, it is bounded by the Buriganga, Turag, Dhaleshwari and Shitalakshya rivers. Dhaka is also the largest Bengali-speaking city in the world.

Muslin, a Phuti carpus cotton fabric of plain weave, was historically hand woven in the areas of Dhaka and Sonargaon in Bangladesh and exported for many centuries. The region forms the eastern part of the historic region of Bengal. The muslin trade at one time made the Ganges delta and what is now Bangladesh into one of the most prosperous parts of the world. Of all the unique elements that must come together to manufacture muslin, none is as unique as the cotton, the famous "phuti karpas", scientifically known as Gossypium arboreum var. neglecta. Dhaka muslin was immensely popular and sold across the globe for millennia. Muslin from "India" is mentioned in the book Periplus of the Erythraean Sea, authored by an anonymous Egyptian merchant around 2,000 years ago, it was appreciated by the Ancient Greeks and Romans, and the fabled fabric was the pinnacle of European fashion in the 18th and 19th century. Production ceased sometime in the late 19th century, as the Bengali muslin industry could no longer compete against cheaper British-made textiles.
