In its very early years, Butler County was a vast wilderness of untamed forests. The fi rst pioneers suffered insurmountable odds while scratching out an existence in this frontier west of the Allegheny River. With determination, they succeeded, and the 1800s brought the development of many towns from the scant settlements. Butler City, the county seat, was laid out in 1800, and many smaller towns followed suit. With the arrival of oil after the Civil War, the county grew. The railroads and trolley lines that expanded into the area furthered the growth and helped industries prosper. Butler County Revisited celebrates the history of the area with 200 postcards, including scenes of the Chicora Whip Factory, a Memorial Day parade in Evans City, the Buhl Trolley Trestle over Connoquenessing Creek, and a large bear wrestling his trainer on Bruin Street.
