In 1791, Herkimer County was created as one of three counties split off from Montgomery (the other two being Otsego and Tioga counties) as New York State was developed after the American Revolutionary War. Its area was much larger than the present county, however, and was reduced subsequently as more counties were organized.

Part of Herkimer County was included in the Macomb’s Purchase of 1791, during the wide-scale sale of public lands after the state forced Iroquois tribes allied with the British during the war to cede their territory. Suddenly the state was selling 5 million acres (20,000 km) of land in upstate, central and western New York.

In 1794, Onondaga County was split off from Herkimer County. This county was larger than the current Onondaga County, and included the present Cayuga, Cortland, and part of Oswego counties.

In 1798, portions of Herkimer and Tioga counties were taken to form Chenango County.

Another part of Herkimer was split off to form Oneida County. It was then larger than the current Oneida County, including the present Jefferson, Lewis, and part of Oswego counties.

In 1802, parts of Herkimer, Clinton and Montgomery counties were combined to form the new St. Lawrence County.

The rural economy was first based on general agriculture and then wheat, but after the opening of the Erie Canal, Herkimer farmers found that they could not compete with grain farmers to the west. By the mid-19th century, they had begun to specialize in dairy farming and created a cheese industry that supplied the New York City market, among others.

During the American Civil War, Herkimer contributed five companies to the 34th New York Volunteer Infantry Regiment, leading to the unit’s nickname “The Herkimer Regiment”.

The Herkimer County Jail, constructed in 1834, was used to hold the murderer Chester Gillette before his trial at the Herkimer County Courthouse. The jail is now disused, except for tours by the Herkimer County Historical Society.

By the late 20th and early 21st centuries, some small farmers had begun to revive an artisan cheese industry and sustainable dairy farming here and in other parts of the central state. In 2008 New York had the third-largest milk production in the nation and was fourth-ranking in production of cheese, according to Cornell University. It has several inter-disciplinary programs related to the dairy industry.

The Herkimer County shootings took place in 2013, killing five people.
