Question: What, in regards to women voting, happened in the 71st year of the 20th century?

Some Swiss cantons approved this in 1959, while at the federal level it was achieved in 1971 and, after resistance, in the last canton Appenzell Innerrhoden (one of only two remaining Landsgemeinde) in 1990.
