Since the Vedic era, the State's primary role has been to defend life and protect the people, despite the many shifts in government structure. Criminal justice and the internal security system's structure are intertwined with religious, ethical, and political institutions of all kinds. Since the police are responsible for protecting the public from the dangers of public accidents and criminal acts, the term "police" can be used to refer to them. Ancient, Medieval, British, Pre-Independence, Post-Independence, and Ancient times have all contributed to the development of police forces (320-1200 A.D). To say that the Indian police force was founded by the British is to misrepresent the country's history and the contributions of the people who lived and worked there throughout the colonial period. The East India Company was inspired by the Napier police to establish a uniform police force modelled after the Irish Constabulary. The British Indian Government established a police commission in 1860 following the first war of the uprising in 1857. Though the tasks of the police should be solely civil, not military, the organisation and discipline in which they perform their duties should be similar to those found in a military organisation, according to one of the Commission's guidelines. We have a police system based on this charter. With slight changes, the Police Act of 1861 established the essential foundations of police organisation in India. As a result, police departments at the state and local levels are distinct and have varying levels of resources and equipment. Despite their striking resemblance in organisational structure and operation, each state police force has its own purpose, vision, and history. In this paper we have tried to trace the history of police in India, theoretical perspective and evolution of the modern police system in the world to know how it will help in police reforms and community policing.
