TheCity of Greater New York was theconsolidation of theCity of New YorkwithBrooklyn, westernQueens County, andStaten Island,[1][2] which took effect on January 1, 1898.[3] New York had already annexedthe Bronx (west of theBronx River in 1874,[4][5] east of the Bronx River in 1895), so the consolidated city sprawled across five counties, which became thefive Boroughs of modern New York. Eastern Queens County was excluded and later becameNassau County.[6][7]
New York City had been founded in the 1620s by the Dutch asNew Amsterdam at the southern tip of the island ofManhattan. The English conquered the territory and established theoriginal twelve counties of the province of New York in 1683; one of these was the City and County of New York. A 1691 law defined New York City to be the entirety of Manhattan, while Manning's Island (nowRoosevelt Island), the Barn Islands (nowRandalls and Wards Islands), and the Oyster Islands (nowLiberty Island,Ellis Island andBlack Tom) were New York County.[8] Towns had been established in the rest of the province by 1691, and were reincorporated after theAmerican Revolution in 1788.[9]
Brooklyn had been chartered by the Dutch in 1646; the Town of Brooklyn was one of the towns incorporated by 1691[8] and reestablished in 1788.[10] It was located within Kings County,[8] another county established by the English in 1683. It was incorporated as a village in 1814 and as a city in 1834. Originally comprising what is nowDowntown Brooklyn, it annexed its surroundings through the 19th century and grew to encompass all of Kings County in 1895. By the1890 United States census Brooklyn had become the fourth-largest city in the United States.
Since the late 1820s, there had been some discussion of a unified city. In 1857, theNew York State Legislature resolved that the region surrounding New York City should become one body, to improve harbor facilities and link the systems of trade.[11] They attempted to do so by government vote, but distrust of large projects killed the plans.[12]
The consolidation movement was the work of local, city, and state politicians, most prominentlyAndrew Haswell Green, the president of the "Greater New-York Commission"[13] and "The Father of Greater New York".[14] Green was a member of the Board of Commissioners of Central Park, which provided him a platform to push his views.[15]

The next challenge to the independence of the boroughs was a self-promoted and government-appointed commission. The commission led the "Vote for Greater New York" movement.[13] Some opponents derided the effort as "Andy Green's hobby", but eventually they were proven wrong.[16] The center of the plan was the consolidation of the twin cities of New York and Brooklyn, whose fire departments had been merged into a Metropolitan Fire District in 1865.[17] The addition ofLong Island City and various rural areas anticipated future development of those areas. WithRepublicans historically more powerful in Brooklyn andDemocrats elsewhere, partisan politics played a role: each major political party hoped to dominate the consolidated city.

The plan required a referendum in all affected areas, though the organizers of the referendum clearly had a bias towards the consolidation. They even released a full-page advertisement inThe New York Times before the vote took place, urging them to vote "For Consolidation".[13] An argument for consolidation was that the unconsolidated city would soon be surpassed byChicago as the most populous city in the United States.[6]
Opposition, concentrated in Brooklyn and other outlying districts, focused on loss of local control and fears of ethnic and racial minorities. Independence-minded Brooklynites did not want their regional identity to be overtaken by New York.[18] Some newspapers such as theBrooklyn Daily Eagle argued that consolidation would destroy the mostly homogeneous,Protestant character of the city.[4]
Opposing newspapers were accused of seeking to retain the revenues of official advertising, while opposing politicians were accused ofgraft. Concerns over how Brooklyn's water supply would be maintained and how future financial backing would be possible were legitimate.[19] Considerations of finance and water supply prevailed, and the people of Brooklyn voted by a narrow margin to consolidate.[20][21][22]

The termCity of Greater New York was never a legal or official designation; both the original charter of 1898 and the newer one of 1938 use the name ofCity of New York.[4] It is used today only to refer to the time period when the consolidation took place.[23]
Each consolidated county remained a county in relation to the state, but also became aborough within the city. The Bronx reunited to form a fifth borough that shared New York County withManhattan. A separate Bronx County wasestablished in 1914, making the present New York County co-extensive with the Borough (but not the island) of Manhattan.
On December 14, 1894, the State Board of Canvassers released the official tally of the referendums, along with other races. The options listed on the ballot were "For Consolidation" and "Against Consolidation". TheNew York Times reported the results:[24]

Since the enlarged city contained the majority of the state ofNew York's population, and the enlargement increased the city's already enormous power within the state, thestate legislature established certain oversight powers within the city. For example, some issues of taxation and changes in governmental procedures require state approval or granting of specifichome rule powers.
Conversely, theState Constitution was amended to provide that no city could elect the majority of the State Assembly, a provision later struck down by theU.S. Supreme Court in 1964 as violating theFourteenth Amendment to the United States Constitution.[25] TheNew York City Board of Estimate, created in the consolidation charter with equal votes for each borough, wasstruck down on similar grounds in 1989.
Staten Island is geographically the most distant of the five boroughs, linked to the other four only bya single bridge, theStaten Island Ferry, andone NYC Ferry route. It is also not connected to theNew York City Subway. In 1993, it held a non-bindingreferendum on the issue ofseceding from New York City to become an independent city and county.[26] Many Staten Island politicians, including SenatorJohn J. Marchi and AssemblymanEric N. Vitaliano supported the movement.[27][28] Vote Yes, Inc. was formed as anonpartisan,grass-roots organization in January 1990. Its initial purpose was to secure a "yes" vote for the November 1990 referendum on Staten Island secession.[29]
Ultimately, 65% of Staten Island residents voted to secede, through the approval of a newcity charter making Staten Island an independentcity, but implementation was blocked in theState Assembly.[30][31] The Staten Island secession movement was defused by the election ofRudy Giuliani as New York City mayor, who fulfilled two of the borough's biggest demands: making the Staten Island Ferry free in 1997[32] and closing theFresh Kills Landfill in 2001.[33]
The topic of Staten Island's secession continues to be debated into the 2020s,[34] and borough presidentVito Fossella announced in 2024 that his office would conduct a study to determine whether it was feasible for Staten Island to secede from the rest of the city.[35] A study by theNew York City Independent Budget Office the same year found that, if Staten Island were to secede, it would incur annual deficits of $171–199 million.[36]
North Hempstead, Oyster Bay and the rest of Hempstead were excluded from the vote.
The area included a radius of twenty miles, with the city hall in New York as a center to circumscribe it
