Let's see, we have Civil War, or War between the States, or the War of Northern Aggression. Take your pick, I can even supply you with a list of soldiers and units. And some very famous battles also.
Of course there are the wars after that one which also need their warriors added.
Like Native American Studies? The three main nations in AR were Caddo, Quapaw, and Osage. Cherokee came later. There are mounds that date back 6,000 years or more. Some are kept secret to prevent looting.
Notables... Arkansas is full of famous people. Some only on a local level, some on the national level. Johnny Cash and Hazel Walker, just to name a couple. Oh yeah, and a president. And two Miss USA's.

Of course I think there should be a Politicians of AR project.

And the population still needs to be found or created.
