Between 1775 and 1865, the United States of America fought three defining conflicts. The American Revolution (1775-1783) gave us our independence. The War of 1812 (1812-1815) secured that independence, giving notice to the monarchies of Europe that we would not allow interference in our affairs. The Civil War (1861-1865) decided just what kind of nation America would be. On this page you will find some of our best content organized into collections.
