Bergen County, NJ

History

On November 30, 1675, the settlement Bergen and surrounding plantations and settlements were called Bergen County in an act passed by the province's General Assembly. In 1683, Bergen (along with the three other original counties of East Jersey) was officially recognized as an independent county by the Provincial Assembly.

Initially, Bergen County consisted of only the land between the Hudson River and the Hackensack River, extending north to the border between East Jersey and New York. In January 1709, the boundaries were extended to include all of the current territory of Hudson County (formed in 1840) and portions of the current territory of Passaic County (formed in 1837).

In 1837, Passaic County was formed from parts of Bergen and Essex counties. In 1840, Hudson County was formed from Bergen. These two divisions took roughly 13,000 residents (nearly half of the previous population) from the county's rolls.
