History
Founded in 1683
An old deed may name a county that no longer exists, or a boundary that has since moved.
Bergen County was created on 7 March 1682/1683 as one of four original counties in East New Jersey, named after Bergen Township. When the East and West Jersey Proprietors surrendered their rights to Queen Anne in 1702, the two colonies were united into the royal province of New Jersey, and Bergen became a county within it with unchanged boundaries. In 1773, King George Iii approved the boundary between New Jersey and New York as determined by a commission; Bergen lost territory to Orange County. The county was reduced further through the creation of Passaic County in 1837 and Hudson County in 1840, though it gained back some territory from Hudson in 1852.
