Law enforcement history dates back to ancient civilizations, where rulers appointed officials to maintain order and enforce laws. In ancient Mesopotamia, for example, the Code of Hammurabi established a system of justice, and officials known as "watchmen" were responsible for public safety. Over time, various societies developed their own policing methods, often influenced by cultural and political factors. In the United States, modern law enforcement began in the early 19th century with the establishment of the first organized police force in Boston in 1838. This was followed by the creation of police departments in other major cities, leading to the development of formal training and standards for officers. Today, law enforcement agencies continue to evolve, adapting to new challenges and technologies.
