More can be written -- indeed, I found only one previous answer, but maybe that's because I have bad search terms. Anyway, you might like to start with "In the United States, why did women in western states get the right to vote before women in eastern states did?" by /u/sunagainstgold .

But this is not to discourage discussion. More questions, data, and debate are welcome.
