A scarce separately issued broadside map produced at the beginning of the American Civil War. This map shows the new territories that were made after southern states seceded. As the trans-Mississippi region developed during the 1850s, there was a call to break up the very large territories into smaller ones. However, every newly created territory had an impact on the power struggle in Congress over the issue of slavery, so between 1854, with its Kansas-Nebraska Act, and 1860, no new territories were created. After secession, the northerners in Congress were able to act quickly and create three new territories: a large Dakota Territory, Territory of Nevada, and Colorado Territory- all present on this map. Another feature of this map is the depiction of a never-existent horizontal border between the free territory of New Mexico and slave territory of Arizona. On August 1 1861, the Confederacy established Arizona Territory, consisting of the southern half of the Union's New Mexico Territory; the Union still claimed the whole territory. The region was sometimes called Arizona before 1863, despite the fact it was still part of the Territory of New Mexico until 1912. Two large inset maps show County map of Virginia, and North Carolina and County map of Pennsylvania, New Jersey, Maryland, and Delaware. Smaller inset maps show Hampton Roads, Washington, D.C., Pensacola Bay, Charleston Harbor, New Orleans, Louisiana, Baltimore and Richmond.
