Windsor is a town in Windsor County, of the Southern Windsor County region, and is known as the birthplace of Vermont, where the state constitution was signed.

Before joining the United States as the 14th state, Vermont was an independent republic known as the Vermont Republic. Windsor was the capital of the Vermont Republic from 1777 to 1791, and acted as the first capital place for the State of Vermont until 1805 when Montpelier became the official capital.

Windsor is known in Vermont history as the location of the framing of the constitution of Vermont, which was unique in a number of ways: it was the first to prohibit slavery, the first to establish universal manhood suffrage without requiring ownership of property, and the first to establish a system of public schools.
