The United Colonies of New England, commonly known as the New England Confederation, was a confederal alliance of the New England colonies of Massachusetts Bay, Plymouth, Saybrook (Connecticut), and New Haven formed in May 1643. Its primary purpose was to unite the Puritan colonies in support of the church, and for defense against the American Indians and the Dutch colony of New Netherland. It was the first milestone on the long road to colonial unity and was established as a direct result of a war that started between the Mohegan and Narragansett Indian tribes. Its charter provided for the return of fugitive criminals and indentured servants, and served as a forum for resolving inter-colonial disputes. In practice, none of the goals were accomplished.The confederation was weakened in 1654 after Massachusetts Bay refused to join an expedition against New Netherland during the First Anglo-Dutch War, although it regained importance during King Philip's War in 1675. It was dissolved after numerous colonial charters were revoked in the early 1680s. John Quincy Adams remarked at a meeting of the Massachusetts Historical Society on the 200th anniversary of the Confederation's founding: The New England confederacy was destined to a life of less than forty years' duration. Its history, like that of other confederacies, presents a record of incessant discord-of encroachments by the most powerful party upon the weaker members, and of disregard, by all the separate members, of the conclusions adopted by the whole body. Still the main purpose of the union was accomplished.

The Natchaug Trail is a Blue-Blazed hiking trail "system" which meanders through 19.5 miles (31.4 km) of forests in northeast Connecticut—primarily in Windham County. It is maintained by the Connecticut Forest and Park Association. Its southern trailhead begins in the James L. Goodwin State Forest in the towns of Chaplin, Connecticut and Hampton, Connecticut and the northern terminus is at its intersection with the Nipmuck Trail in Natchaug State Forest in Eastford, Connecticut. For much of its length the Natchaug Trail travels through two Connecticut state forests—the James L. Goodwin State Forest and Natchaug State Forest as well as the much smaller Nathaniel Lyons Memorial Park. Camping permits may be obtained by backpackers for both state forests. In addition to the Nipmuck Trail there are several smaller hiking trails which connect to the Natchaug Trail as well as several park and forest roads and the multi-use Airline State Park Linear Trail. In Natchaug State Forest the CCC Trail is a historic loop trail which was built by the Civilian Conservation Corps during the Great Depression in the 1930s. Two of the several trails inside the James L. Goodwin State Forest are connected to the Natchaug Trail have recently been blazed as official CFPA trails. According to signs at the James L. Goodwin State Forest the White Trail is being (or has been) re-blazed as a blue-white trail named the "Pine Acres Lake View Trail". A CFPA blue-orange blazed trail also intersects with the Natchaug Trail during the stretch between Pine Acres Lake and Black Spruce Pond.
