In 1675, rumors of unrest among the indigenous peoples began to surface. The rumors proved accurate, and in the summer, King Philip's War began, a war between a number of tribes and the New England settlers. The war extended through parts of four colonies, with Simsbury on the western edge of the conflict. At the time, it was seen as a frontier settlement. The conflict was largely over by August 1676, although it did not formally end until a treaty was signed in 1678.
