Did anything good come out of the Civil War?

the long version

In addition to putting an end to the inhumane institution of slavery, the Civil War also spurred important inventions that improved people s lives, such as canned food, pocket watches, federal paper currency, and standard sizes for shoes. Although medical technology lagged behind the development of new weapons that could kill and maim more soldiers than ever, there were advances in amputation techniques and anesthesia delivery. Additionally, the railroad and telegraph systems were hugely beneficial to the war effort and became far more entrenched in daily life after the end of hostilities. Timelines and fun facts help illuminate these innovations of the Civil War. Detailed Table of Contents, Full-color photographs, For Further Information Section, Glossary, Index, Web Sites.
