The Bangladesh Police (বাংলাদেশ পুলিশ) of the People's Republic of Bangladesh is the national law enforcement agency of Bangladesh, operating under the Ministry of Home Affairs. It plays a crucial role in maintaining peace, and enforcement of law and order within Bangladesh. Though the police are primarily concerned with the maintenance of law and order and security of persons and property of individuals, they also play a big role in the criminal justice system. Bangladesh police played an important role during the Bangladesh Liberation War.
Details of policing activities during the middle age are challenging to find. However, during the periods of the great sultans, an official holding the position of Muhtasib used to perform the duties of policing. This person was the chief of police, in charge of public works, and the inspector of public ethics simultaneously. In urban areas, Kotwals were responsible for performing police duties. The policing system introduced by Sher Shah Suri was further organised during the period of Emperor Akbar: the Emperor organised his administrative structure introducing Fouzdari (the principal representative of the Emperor), Mir Adal and Kazi (the head of judicial department), and Kotwal (the chief police official of larger cities). This system was effective in maintaining the law and order in cities, and was implemented in Dhaka. Many district sadar police stations are still called Kotwali police stations. In the Mughal period, Kotwal emerged as an institution.
A Fouzdar was appointed to every administrative unit of the government (district), under whom there were some artillery and cavalry forces. There was a disciplined police system during the Mughal period, though there was no professional police force like that in the British period.
In the early stage of the Industrial Revolution, when England was facing grave crisis due to socio-economic transformation, the necessity of an effective organised police service was keenly felt.
