[1] The original Belarusian Militsiya was founded on 4 March 1917 during the events of the February Revolution, when prominent Bolshevik leader and politician Mikhail Frunze was appointed temporary police chief of the local Minsk civilian militia.

In Belarus, as well as in newly formed Russian SFSR as a whole, the Militsiya replaced the previous Tsarist police services such as the Okhrana.

1917, days after the October Revolution took place, the People's Commissariat for Internal Affairs (NKVD) issued a decree on the first normative act defining the creation of the Soviet Militsiya.

On 1 March 1991, the Supreme Soviet of Belarus enacted the Law "On the Police", which is the main legal act regulating the activities of the internal affairs bodies of an independent republic.

On 17 July 2007, the National Assembly of Belarus adopted a law effectively making the Belarusian police a fundamental and flagship agency of the MVD/MUS.
