The Persian Gendarmerie, or Iranian Gendarmerie also called the Government Gendarmerie (Persian: ژاندارمری دولتی‎‎ Žāndārmirī-ye Daulatī), was the first modern highway patrol and rural police force in Persia. A paramilitary force, it also played a significant part in politics from its establishment in 1910 during the Qajar dynasty until the advent of the Pahlavi dynasty in 1921. It continued to serve until the end of the Pahlavi era and was modernized into the Imperial Iranian Gendarmerie. Originally established as a constitutional army, the force employed Swedish officers in command of Iranian personnel to perform both traditional police duties and conduct military campaigns against tribal forces. In 1991 the Iranian Gendarmerie was merged with other police forces to form the Law Enforcem
