Something I salvaged from the original AHN. I plan on using it for some other projects, like 32nd State and the Great War battlefield. A couple of notes; Kansas was admitted as a slave State due to the Kansas-Nebraska Compromise. Durango is the only southern State to not originally be a slave State, though it was forced into the CSA. That threw off the whole free-slave balance in the Senate which led to a later Civil War. A couple have N/A in the admission date slot; those were territories first admitted as States in the CSA, and thus joined the Union after the Restoration.
