In the 1860s, Americans in one part of the country went to war against Americans in another part of the country. This type of war is called a civil war. The Civil War between the northern states and the southern states lasted four years, from 1861 to 1865. The war happened after decades of arguments between the North and the South. When the fighting started, it caused terrible destruction to the country, and over 800,000 people died. After the war was over, there were more arguments about how the war should be remembered. New Hampshire played a role in all of these events, and the Civil War had a big impact on people’s lives in the Granite State.
