History[change | change source]
Brooklyn is named after a Dutch town called "Breukelen". Dutch people were the first people from Europe to live in the area. When they got there, there were already some Native American people living there called the Lenape. The Dutch set up the city in 1634 as part of the colony of New Netherland.
During the 19th century Brooklyn expanded and filled Kings County. It remained a separate city before the people there voted to join New York City in 1898. Today, many parts of Brooklyn are home to people who are mostly from one culture or ethnicity, and other parts are mixed.
