During the Jim Crow era, traveling in the United States for African-Americans was difficult and often dangerous. Motels and restaurants didn’t have to serve you if they didn’t want to. “Sundown towns”—places where it was unsafe to be black at night—dotted the nation’s geography. If you were driving around the country, the only way to know if you were safe was by word-of-mouth.

Drought conditions in the Western part of the United States have allowed an old Nevada town once submerged deep beneath Lake Mead to emerge from its watery grave.

When the Mormons left in 1871, outlaws — including horse thieves and cattle rustlers— moved in. The town was eventually settled by people attracted by the region’s prime farming land.

There's a map making the rounds on Facebook right now, which is being shared as if it's a map of pre-contact North America. You can find it here. But it doesn't show pre-contact North America at all — it's trying to show what the boundaries of the First Nations & Inuit would look like in 2015 if contact had never happened.

When thinking of time, realize that the US Constitution, who's ratification was ancient history when I was in school, has only been around TWO whole human lifetimes. All of US history from the Revolution till now can be contained in the life and experiences of three people.

Francis Scott Key pens a poem which is later set to music and in 1931 becomes America’s national anthem, “The Star-Spangled Banner.” The poem, originally titled “The Defence of Fort McHenry,” was written after Key witnessed the Maryland fort being bombarded by the British during the War of 1812.
