Main lines and branches of railroads were being built across Arkansas in the late 1880s. By 1898, two of them—the St. Louis Southwestern Railway running roughly north–south, and the Missouri and North Arkansas Railroad (M&NA) running roughly east–west—crossed. A post office with the name Fargo was established at the crossing, but it was not yet a town. In 1911, the two railways built a depot in Fargo.
At least 33 settlements formed along the railroad as the M&NA was built, including Fargo, where Leroy Mahon owned the farmland at the railroad crossing.
Leroy Mahon platted the land and created a settlement for Black families. In doing so, he created a freedmen's town.
