The Civil Guard is a law enforcement agency in Spain that operates under the Ministry of the Interior. Established in 1844, it is responsible for maintaining public order, preventing crime, and ensuring safety in rural areas and small towns. The agency combines military and civil functions, making it unique among police forces. Members of the Civil Guard are known as "guardias civiles" and wear a distinctive green uniform. They handle various tasks, including traffic control, border security, and counter-terrorism efforts. The Civil Guard also collaborates with other law enforcement agencies to address national and international security issues.
