Juniata County is located in central Pennsylvania and has a rich history dating back to the early 18th century.

European settlers began arriving in the area in the early 1700s, with the first permanent settlements established around 1755.

During the American Revolution, Juniata County played a significant role. In 1776, Mifflintown, the county seat, was founded and named after Thomas Mifflin, a prominent patriot and Pennsylvania Governor. The area saw numerous skirmishes and battles during the war, as it was strategically located along the Susquehanna River.

In the 19th century, Juniata County became known for its agricultural industry, with farming and dairy becoming the main economic drivers. The county's rich soil and access to transportation through the Pennsylvania Canal and later the Pennsylvania Railroad allowed for the growth of these industries. Manually-operated gristmills and sawmills were also essential to the county's development.

Today, Juniata County remains a predominantly rural area, known for its beautiful landscapes and small-town charm.
