Parliamentary elections were held in Austria on 17 October 1920,[1] although they were not held in Carinthia until 19 June 1921 and in Burgenland until 18 June 1922.[2] They were the first regular elections held after a permanent constitution was promulgated two weeks earlier.
The result was a victory for the Christian Social Party, which won 85 of the 183 seats.[3] Voter turnout was 80%.[4]
Following the election, a coalition was formed between the CS and GDVP.
