History

The area that would become Rockland County was originally inhabited by Algonquian-speaking Indians, including Munsees, or Lenni Lenape.

In 1609, Henry Hudson, thinking he had found the legendary "Northwest Passage", sailed up the river that would one day bear his name and anchored near the area that is now Haverstraw before continuing to disillusionment at Albany.

The area was originally settled by the Dutch. A number of unique Dutch-style red sandstone houses still stand, and many placenames in the county reveal their Dutch origin.

When the Duke of York (who became King James II of England) established the first twelve counties of New York in 1683, present-day Rockland County was part of Orange County. Orangetown was created at the same time, originally encompassing all of modern Rockland County. Haverstraw was separated from Orangetown in 1719 and became a town in 1788; it included the present-day Clarkstown, Ramapo and Stony Point. Clarkstown and Ramapo became towns in 1791, followed by Stony Point in 1865. Rockland County was split from Orange County in 1798.

During the American Revolution, when control of the Hudson River was viewed by the British as strategic to dominating the American territories, Rockland saw skirmishes at Haverstraw, Nyack and Piermont, and significant military engagements at the Battle of Stony Point, where General "Mad" Anthony Wayne earned his nickname. George Washington had headquarters for a time at John Suffern's tavern, the later site of the village of Suffern.

British Major John André met with American traitor Benedict Arnold near Stony Point to buy the plans for the fortifications at West Point. André was captured with the plans in Tarrytown on his way back to the British lines; he was brought to Tappan for trial in the Tappan church, found guilty, hanged and buried nearby.

The American Industrial Revolution was supplied, in part, from forests and iron mines in Rockland County. Resource utilization extracted a heavy toll on the region, especially from lumbering and agriculture, since the poor, thin soils on hillsides were easily depleted. By the early 1900s development along the lower Hudson River had begun to destroy much of the area's natural beauty.

Many unsuccessful efforts were made to turn much of the Hudson Highlands into a forest preserve. However, when the State of New York tried to relocate Sing Sing Prison to Bear Mountain in 1909, some of the wealthy businessmen who had homes in the area, led by Union Pacific Railroad president E. H. Harriman, donated land as well as large sums of money for the purchase of properties in the area of Bear Mountain. Bear Mountain/Harriman State Park became a reality in 1910, and by 1914 it was estimated that more than a million people a year were coming to the park.
