HistoryA character grade: shown, never part of Greenbrier’s overall grade.
Arkansas towns list more on the Register than most of the country (a typical Arkansas town has 20.5 per 10,000 residents, the U.S. 2.4), so Greenbrier’s 3.3 sits below most of its state (30% of Arkansas towns have fewer) while its 2 listings outnumber those of 60% of U.S. towns.

What stands out about Greenbrier’s past

Prior to European settlement, Native American tribes, including the Quapaw and later the Cherokee, lived in the area. Several historical figures of the Wild West such as Jim Bowie and Jesse James passed through the Greenbrier region toward Oklahoma and Texas. The Wiley brothers settled near East Fork Cadron around 1818, about 8 miles (13 km) east of today's Greenbrier. In 1837, Jonathan Hardin settled near the Wiley settlement. Also in the early 19th century, the Casharagos settled north of Greenbrier in the present community of Republican.
