This map differentiates between states and territories that remained a part of the Union during the Civil War and those that seceded, both before and after the onset of war.

The map key delineates between states that seceded before and after "the outbreak of war." Confederate troops had bombarded Charleston's Fort Sumpter on April 12, 1861, marking the official beginning of the Civil War.

Public Domain is a copyright term that is often used when talking about copyright for creative works. Under U.S. copyright law, individual items that are in the public domain are items that are no longer protected by copyright law. This means that you do not need to request permission to re-use, re-publish or even change a copy of the item. Items enter the public domain under U.S. copyright law for a number of reasons: the original copyright may have expired; the item was created by the U.S. Federal Government or other governmental entity that views the things it creates as in the public domain; the work was never protected by copyright for some other reason related to how it was produced (for example, it was a speech that wasn't written down or recorded); or the work doesn't have enough originality to make it eligible for copyright protection.
