Slovenia: women allowed to vote in municipal elections
After WWI, on May 15, 1920 the Slovenian People’s Party granted universal suffrage for men and women at the municipal level.

The opponents of universal suffrage, local liberals and leaders in Belgrade managed to dismiss the right just two months before the local elections in 1921.
