In 1687, Wethersfield, Connecticut, was a small, burgeoning colonial settlement characterized by a tight-knit community of Puritan settlers. The town, founded in 1634, was primarily agrarian, with residents engaged in farming, livestock raising, and trade along the Connecticut River. The population was relatively small, with a focus on religious and communal values, and the local government was influenced by the Puritan faith, emphasizing moral conduct and community cohesion. Daily life revolved around agricultural cycles, church services, and community gatherings, reflecting the early colonial lifestyle of New England.
The Connecticut charter was hidden in a hollowed-out tree, known as the Charter Oak, during the late 17th century. When King James II attempted to revoke the charter in 1687, colonial leaders hid it to protect their self-governance. The tree became a symbol of freedom and resistance for the colonists. Eventually, the charter was discovered, but it remained a significant part of Connecticut's history.
