Old Allegany County Courthouse

Located in western New York, Allegany County has a rich history that dates back thousands of years. The area was originally inhabited by Native American tribes, most notably the Seneca Nation. European colonizers, such as French and British explorers, began to arrive in the 17th century to trade with the indigenous peoples.

In the late 18th and early 19th centuries, the area underwent a significant transformation with the arrival of pioneers and settlers from the east. Allegany County was officially established in 1806 and named after the Allegheny River, which flows through much of the county. The construction of the Genesee Valley Canal in the 1830s further stimulated the region's economic growth, as it provided a vital transportation route for trade and commerce.

Allegany County played a role in the Underground Railroad during the mid-19th century, as abolitionists helped enslaved individuals escape to freedom through a network of secret routes and safe houses. The county also witnessed significant industrial development during this time, with the establishment of several manufacturing and mining operations.

In the following decades, Allegany County experienced both prosperity and challenges. The decline of the canal system and the impact of the Great Depression led to economic difficulties, but the county managed to adapt and diversify its economy. Today, Allegany County continues to be known for its agriculture, manufacturing, and outdoor recreational opportunities, while also preserving its historical heritage through various museums and landmarks.
