The origins of the name Dhaka are uncertain. Once ''dhak'' trees were very common in the area and the name may have originated from it. Alternatively, this name may refer to the hidden Hindu goddess Dhakeshwari, whose temple is located in the south-western part of the city. Another popular theory states that Dhaka refers to a membranophone instrument, ''dhak'' which was played by order of Subahdar Islam Khan I during the inauguration of the Bengal capital in 1610.
