The forgotten vote where NYC tried to leave the Union and New York State

NYC’s mayor pitched secession in 1861

Many Americans know South Carolina fired the first shots of the Civil War.

Fewer know that New York City’s mayor asked the city to leave the Union just weeks earlier — and the city council said yes.

On January 6, 1861, Mayor Fernando Wood stood before the Common Council and proposed that New York City break away from both the Union and New York State to become the “Free City of Tri-Insula.”

His reason? To keep trading cotton with the South.

The council — a notoriously corrupt group nicknamed “The Forty Thieves” — approved the proposal and had copies printed across the city.

The New York Times openly mocked it. But for a brief moment, the North’s largest port city had officially voted to side with Southern interests.

The council reversed itself only after Confederate cannons opened fire on Fort Sumter in April. Had they stuck to their vote, they would have been traitors facing the gallows.

Wood Called It Tri-Insula

Mayor Wood wanted to create a sovereign city-state called the Free City of Tri-Insula, Latin for three islands, incorporating Manhattan, Long Island, and Staten Island.

He modeled the idea after European trading cities like Hamburg, Bremen, and Frankfurt, which operated independently while maintaining commerce with surrounding nations.

Wood argued that if the Union dissolved, New York City could survive on import tariffs alone, funding its local government without taxing its people.

The pitch was simple: why should the wealthiest city in America answer to Albany or Washington when it could answer to no one?

NYC Was the True Capital of Cotton

By 1860, New York received an estimated 40 percent of all cotton revenues since it supplied insurance, shipping, and financing services. Trade with the South pumped approximately $200 million annually into the city’s economy.

New York City banks funded the plantations that spread across the Deep South, and New York merchants supplied everything from pianos to the clothing slaveholders gave their enslaved workers to wear.

Cotton made New York rich, and cotton came from slave labor.

The Entire Economy Ran on Slavery

Although New York ended slavery in 1827, the city profited massively from slave-grown cotton, which accounted for seven-eighths of the worlds supply.

Most New Yorkers did not care that the cotton was produced by enslaved people because for them it became sanitized once it left the plantation.

Wall Street financed slave purchases. Shipping magnates hauled the cotton. Insurance companies covered the cargo.

Mayor Wood himself admitted in 1859 that the citys profits depended upon products only to be obtained by continuance of slave labor.

NYC Despised Upstate New York

The citys resentment toward Albany ran deep.

Wood and his allies saw greater New York City as a polyglot, multiethnic, commercially minded, raucously tolerant society founded by the Dutch, trapped under a state dominated by Yankees of Puritan New England origin.

Upstate legislators had slashed Woods mayoral term, created a rival police force to undermine him, and meddled constantly in city affairs.

Wood declared that Albany had plundered the citys revenues, attempted to ruin its commerce, and taken away its power of self-government.

Congressman Sickles Backed the Plan

On December 10, 1860, pro-secession Congressman Daniel Sickles delivered a fiery speech on the House floor declaring that secession would not end at the South.

He told his colleagues there was no sympathy between New York City and the state, and that the imperial city would repel the hateful cabal at Albany and open its gates to the civilization and commerce of the world.

At least three members of the citys congressional delegation supported the plan, along with three daily newspapers.

Sickles later became a Union general and lost his leg at Gettysburg.

Secret Meetings at Woods Estate

Before November 1860 was out, Wood was holding private secession planning meetings at his sprawling country estate on whats now the Upper West Side.

Invitations went out to real estate tycoon William Astor, financier August Belmont, and Democratic Party leader Samuel Tilden. Financier George Law was sent to Washington to rally the citys congressional delegation.

Meanwhile, worried officials in Albany tasked Metropolitan Police Superintendent John Kennedy with gathering intelligence on the mayors schemes.

Reporters began receiving leaks that Wood might actually lead the city out of the Union.

Lincoln Got a Hostile Reception

Many New Yorkers gave Lincoln a cold shoulder when he visited on his way to the inauguration.

The anti-Lincoln vote in New York City was 62 percent, though Republican strength upstate helped Lincoln win the state and the election.

Businessmen warned their workers that if Lincoln won, the South would bolt the Union and take away jobs.

The New York Daily News, edited by the mayors brother, warned workers they would have to compete with the labor of four million emancipated negroes if Lincoln won.

2,000 Merchants Met to Back the South

In December 1860, with Lincoln elected and the threat of secession becoming reality, some 2,000 terrified New York businessmen gathered in support of the South and of secession.

Over 2,000 worried merchants showed up at 33 Pine Street near Wall Street, a veritable Whos Who of the citys commercial establishment, determined to show solidarity with the South.

Attorney Hiram Ketchum told the crowd that if conflict arose between the races, the people of the city of New York would stand by their brethren, the white race.

Fort Sumter Changed Everything Overnight

South Carolinas shocking April 12 attack on Fort Sumter, a federal military base protecting Charlestons harbor, incensed most everyone living north of the Mason-Dixon line, effectively ending the citys move for independence.

According to the New York Times, the tidal wave of support for the Union overwhelmed secessionist sentiment in the city.

What had seemed possible just weeks earlier now looked like treason. The merchants who had backed the South suddenly wrapped themselves in American flags.

100,000 New Yorkers Rallied for Union

On April 20, 1861, an estimated 100,000 people gathered in Union Square, the largest crowd that had ever assembled in the history of the nation until then.

On that day, New York, alongside the rest of the North, proclaimed its loyalty to the United States.

The New York Times reported that the Empire City spoke in tones of thunder for the Union, the Constitution, and the enforcement of the laws.

Flags flew from nearly every building, and the soldiers who had defended Fort Sumter were introduced to roaring cheers.

The Draft Riots Proved the Tensions Remained

In July 1863, violent disturbances erupted in Lower Manhattan, widely regarded as the culmination of working-class discontent with new draft laws.

The riots lasted five days and became some of the bloodiest and most destructive in American history, with Black New Yorkers often the target of the violence.

The riots remain the largest civil urban disturbance in American history.

The same racial and class tensions that had fueled secession talk exploded into the streets, proving that New York Citys loyalty to the Union was complicated at best.
