The Albanian State Police is the national police and law enforcement agency which operates throughout the Republic of Albania. The collapse of the Communist system and the establishment of political pluralism post-1991 brought important changes to the structure of the Albanian Police. The Ministry of Public Order and the General Directorate of Police was established in April 1991, and the new law of July 1991 established the Public Order Police. Nearly 80% of police manpower, i.e. personnel who had served under the previous system, were replaced by new recruits. On November 4, 1991, the Albanian Police was accepted as a member of INTERPOL. The emergency number is 129.
