A referendum abolishes the monarchy in Bulgaria.

A referendum on becoming a republic was held in Bulgaria on 8 September 1946. Official results showed 96% in favour of the change against only 4% in favour of retaining the monarchy, with voter turnout reported to be 92%. The monarchy had effectively ended soon after the coup of 9 September 1944, which saw the Fatherland Front seize power. At that time, the regency council for the head of state, Tsar Simeon II, was replaced by a new council made up entirely of members of the Bulgarian Communist Party, the dominant force of the Fatherland Front.
