The Pennamite-Yankee Wars were a series of three conflicts between settlers from the colonies of Pennsylvania and Connecticut. Settlers from both states had been granted title to lands in what is now northeastern Pennsylvania. The dispute over which state governed the area led to the construction of competing forts. Tensions flared up on three separate occasions, eventually shots were fired until the state's northern boundary was established.
