You sort of brush by a fairly significant point: the right to vote granted in 1776 was rescinded. Why? Research shows that in political developments preceding the civil war, women voted nearly overwhelmingly conservative. That suggests a political bias to exclude their votes. That’s an important piece of women’s history.
Actually, that is referred to in the timeline of women’s suffrage on this site. The rescinding of the right was pretty quickly, and according to available information, few women actually did vote in those early years.
