The Mohawk Valley is a natural passageway connecting the Atlantic Ocean, by way of the Hudson Valley with the interior of North America. Native American Nations of the Iroquois Confederacy lived in the region, and in the 17th century immigrants of Dutch, and the 18th century German, and Scottish settled the area, joined by Italians following the rapid industrialization of the mid-19th century. During the 18th Century, the Mohawk Valley was a frontier of great political, military and economic importance. Colonists, such as Phillip Schuyler, Nicholas Herkimer, William Johnson, trading with the Iroquois set the stage for commercial and military competition between European nations, leading to the French and Indian Wars and the American Revolution. Almost 100 battles of the American Revolution were fought in New York State, including the Battle of Oriskany and defense of Fort Stanwix. A series of raids against valley residents took place during the war; led by John Johnson they were collectively known as the "Burning of the Valleys".
