Elections in the First Czechoslovak Republic

Parliamentary elections in the First Czechoslovak Republic were held in 1920, 1925, 1929 and 1935.

The electoral system of the First Republic was based on the Czechoslovak Constitution of 1920. Parliamentary elections were regulated by Acts 123 and 208 of 1920.

The Czechoslovak parliament at the time consisted of a Chamber of Deputies (300 members) and a Senate (150 members). Parliamentarians were elected under a proportional representation system using multi-member electoral districts. The Hare quota was used in the first count, and the Hagenbach-Bischoff quota in the second count. The President of the Republic was elected by both houses of parliament.

Suffrage was universal, secret and compulsory for all citizens aged 21 years and above for elections to the Chamber of Deputies and aged 26 years and above for the Senate. Voters were required to have lived in their respective constituency for three months to be entitled to vote there. Bankrupt citizens and citizens convicted of crimes could lose their right to vote.

Candidates to the Chamber of Deputies had to be 30 years of age and Czechoslovak citizens for at least three years. Candidates to the Senate had to be 45 years of age and Czechoslovak citizens for at least ten years.

The Ministry of the Interior was charged with organizing the elections.

Initially, the republic had 23 electoral districts for elections to the Chamber of Deputies and 13 electoral districts for the Senate.
