The arrival of European settlers in the late 18th century brought significant changes to Onondaga County. In 1794, the area became part of the newly created Onondaga County, named after the Onondaga people. Syracuse, the county seat and current largest city, was founded in 1820 and quickly grew due to its advantageous location for transportation and industry. The construction of the Erie Canal, completed in 1825, further boosted the region's development by facilitating trade and connecting New York City with the Great Lakes.
By the mid-19th century, Onondaga County became an industrial hub, with a booming salt industry, manufacturing, and trade. The county's salt reserves were highly valuable, earning Syracuse the nickname "Salt City." The region also played a significant role in the abolitionist movement, with notable figures such as Harriet Tubman and Gerrit Smith actively involved in the Underground Railroad.
In the 20th century, Onondaga County continued to thrive, embracing innovation and industry. The area witnessed the growth of Syracuse University, established in 1870, as well as the development of various manufacturing sectors including automobiles, electronics, and defense. Today, Onondaga County remains a vibrant and diverse community, blending its rich history with modern advancements in education, technology, and cultural heritage.
