The National Park Service has launched a website that provides an overview of the Civil War and a guide to more than 1,700 sites around the nation related to the war that divided the nation.
Among those 1,700 sites are more than 100 national parks with Civil War themes. The narrative on the war examines its root causes; biographies of major players, military and civilian; and places within the national park system that help illuminate the war.
The national parks included on the site range from Washington and San Juan Island National Historical Park to the Florida Keys and Fort Jefferson.
You can look up the names of soldiers, sailors and other military personnel by name, state, agency or rank.
You can also follow the adventures of a fictional Civil War-era correspondent whose daily reports are streamed to the website by Twitter.
