Ware was first settled on Equivalent Lands in 1717 and was officially incorporated in 1775. It is named after the English town of Ware, Hertfordshire.

In 1716 a tract of land which was a little more than 11,000 acres (45 km²) in size was granted to John Read. He named it "The Manour Of Peace" and had it in mind to develop it in the style of an English manor anticipating that it would later become a very valuable country estate. He leased out the land and did not sell 1-acre (4,000 m²) until after his death when he gave a gift of 200 acres (0.81 km²) to serve as a ministry lot. As time passed, the town of Ware grew up around the old Congregational meeting house and later became a small center of local manufacturing and commerce.

The actual origin of the name, Ware, is thought to be derived from a translation of the Native American word "Nenameseck," meaning fishing weir (pronounced Ware). The weirs were used to capture salmon that were once abundant in New England waterways.

In 1729, the first grist and saw mills were built on the banks of the Weir River by Jabez Olmstead. During the American Revolution there were at least eight taverns and several inns in the area. Two of the most famous were Ebenezer Nye’s tavern and John Downing’s. After town meetings were held they would often adjourn to the latter establishment. By the 1830s it was not uncommon to see textile mills dotted along the various local rivers. At this point Ware community was making the transition from an agrarian economy to an industrially based society. The post Civil War era (1850s - 1900s) brought a new prosperity to the now established textile mill town. "Ware factory village," as it was known, sprung up overnight and formed the basis for new growth and development.
