Lure:
The consolidation story makes for a fascinating tale. I’ll try to sort it out for you here.
The idea for consolidating NYC (essentially Manhattan) and the City of Brooklyn was an old one. The earliest attempt I found went back to 1827. Despite a few solid attempts, the proposal never gained traction due to distrust and rivalry between the two municipalities.
To understand how it finally happened, you must be familiar with the NYC political landscape at the turn of the century. There were four important political camps that played into the 1898 consolidation picture:
Tammany Democrats (like by Boss Richard Croker),
reform Democrats (like Andrew H. Green, see more below),
regular Republicans (like by Boss Thomas Platt), and
reform Republicans (like Seth Low, Teddy Roosevelt and the Citizens Union)
My personal hero, Andrew Haswell Green – who is considered the Robert Moses of his day for having steered the creation of Central Park and many other grand public works – despised and fought the Tammany wing of his party all his life. Allied to the merchant class of NYC, and a lover of honest efficient government, he resurrected the consolidation concept in earnest in the late 1880’s. His aim was to unite the port of New York – the engine that drove the economy of the whole region – under singular control. Thus he included S.I., all of the present-day Bronx, and the present-day Queens in his plan – not just Brooklyn. But, framed only in economic and social terms, Green’s plan was thwarted by Brooklyn nativists and Manhattanites who did not want to share their tax wealth with the strapped and undeveloped hinterland municipalities.
But the stalemate broke once the idea turned political. In the mid-1890’s the NYS regular Republicans had Tammany Hall on the run following an embarassing GOP-led investigation of the Tammany-controlled NYC Police Department. State GOP Party Boss Tom Platt (who wanted a slice of the big downstate patronage pie that Tammany usually controlled) and reform Republicans (who saw consolidation as a way to root out Tammany for good and bring honest government to the entire area at once) united in favor of Green’s proposal.
It took intense pressure by Platt and his upstate followers to ram the plan through the NYS legislature despite objections from Tammany Dems, elitist Brooklynites, ungenerous Manhattanites and upstaters who feared the creation of a “monster metropolis” downstate. But, by a mere 2 votes the Greater New York Bill passed the legislature in April 1896 (to take effect January 1, 1898).
The Republican triumph faded fast, however, when the alliance between the regular wing and reform wing cracked. Each faction nominated a different mayoral candidate, splitting the GOP vote. In an ironic twist, Tammany candidate Robert Van Wyck thus became the first mayor of Greater NYC.
