Introduction
Criminal law is a crucial part of the legal system that governs crimes, prosecution, and punishment of individuals who violate laws. It ensures justice by defining offenses, establishing penalties, and protecting both victims and accused individuals. This guide explores the fundamentals of criminal law, its key components, common types of crimes, the role of criminal lawyers, and the impact of criminal justice systems worldwide.
What is Criminal Law?

Unlike civil law, which resolves disputes between individuals or organizations, criminal law involves actions that are considered offenses against the state, society, or public welfare.
Criminal law is designed to maintain order, deter criminal behavior, and ensure that offenders face appropriate consequences. Governments enforce criminal law through law enforcement agencies, prosecutors, and the judiciary.
