Fort Lee's location on the bluffs of the New Jersey Palisades, opposite Fort Washington in Manhattan, made it a strategic position during the war.In November 1776, the Battle of Fort Lee took place as part of a British plan to capture George Washington and to crush the Continental Army, whose forces were divided and located in Fort Lee and Hackensack.In 1852, the Erie Railroad began operating major rail services from Jersey City on the Hudson River to points north and west via leased right-of-way in the county.This became known as the Erie Main Line, and is still in use for passenger service today.In the 17th century, the Dutch considered the area comprising today's Bergen and Hudson counties as part of New Netherland, their colonial province of the Dutch Republic.The Dutch claimed it after Henry Hudson (sailing for the Dutch East India Company) explored Newark Bay and anchored his ship at Weehawken Cove in 1609.
Bergen County is divided into 70 municipalities, but has no large cities.
Its most populous place, with 43,010 residents at the time of the 2010 census, is Hackensack, Bergen County is one of the wealthiest counties in the United States, with a median household income of ,708 per the 2010 Census, increasing to an estimated ,677 in 2014, which was almost 18% higher than the ,919 median statewide.
The origin of the name of Bergen County is a matter of debate.
The Erie later leased two other railroads built in the 1850s and 1860s, later known as the Pascack Valley Line and the Northern Branch, and in 1881 built a cutoff, now the Bergen County Line.
There were two other rail lines in the county, ultimately known as the West Shore Railroad and the New York, Susquehanna, and Western.
