One can argue about choosing the next darkest part (the genocide of Native Americans could go here), but any credible short list must include the post-slavery period that lasted from the end of the Civil War until the Civil Rights movement of the 1950s and 1960s.

Arizona will have a two-track voting system for the 2014 election, under a new state policy underpinned by an opinion from the state attorney general.
Arizonans who registered to vote using a federal form will only be allowed to vote in federal races next year. People who registered to vote using Arizona’s state form — which requires proof of citizenship — will be able to vote as usual, casting ballots in everything from local races to state contests to congressional races.
Attorney General Tom Horne’s opinion comes in the wake of a June U.S. Supreme Court ruling that struck down part of state voter-approved law that required proof of U.S. citizenship as a pre-condition to voting.
