History.
The county was first settled by Native Americans who lived there for many years. It was later found by explorer Henry Hudson when he sailed up the Hudson River in the 1600s. Soon after, many English colonists moved to the area, and formed the first towns. The county was involved in the American Revolution, and an important battle took place there. 
After America won its independence, the county remained mainly rural, meaning most of it was farms and forests. This continued until the Tappan-Zee Bridge and Palisades Parkway were opened in the 1950s. These roads connected the county to New York City, allowing people to drive there. This caused more people to move to Rockland.
