City of Greater New York

The City of Greater New York was the consolidation of the City of New York with Brooklyn, western Queens County, and Staten Island, which took effect on January 1, 1898. New York had already annexed the Bronx (west of the Bronx River in 1874, east of the Bronx River in 1895), so the consolidated city sprawled across five counties, which became the five Boroughs of modern New York. Eastern Queens County was excluded and later became Nassau County.
