A New Era Begins

New York City Mayor Zohran Mamdani proclaimed a “new era” as he took the helm of the country’s largest city on New Year’s Day. The 34-year-old democratic socialist, whose star rocketed last year, was publicly sworn in on the steps of City Hall, where he addressed a crowd of thousands in a sweeping inauguration speech attended by top progressive allies.

“My fellow New Yorkers, today begins a new era,” Mamdani said.

Key Takeaways from the Inauguration

Here are five takeaways from Mamdani’s inauguration and his first hours in the mayor’s office:

Mamdani Gets to Work on NY Affordability

Mamdani, whose policy proposals for rent freezes, city-owned grocery stores, universal childcare and fare-free city buses have been criticized as unfeasible, laid out a bold vision for affordability in New York City as he rejected “small expectations” in his inaugural speech.

“Beginning today, we will govern expansively and audaciously. We may not always succeed, but never will we be accused of lacking the courage to try,” Mamdani said in his inauguration. “We will transform the culture of City Hall from one of ‘no’ to one of ‘how.’”

But the new mayor’s progressive agenda faces massive challenges in the Big Apple. Rising housing costs and historic-low vacancy rates are pushing some to leave the city, homelessness doubled between 2022 and 2024, and policy changes at the federal level are set to further squeeze New Yorkers’ pocketbooks. The city ended 2025 with a staggering budget deficit of $380 million, according to the Independent Budget Office.

He’ll also need support on some of his initiatives from New York Gov. Kathy Hochul (D), who has backed Mamdani but expressed reservations about some of his plans, such as his goal to make city buses free to ride.

Nevertheless, Mamdani is charging ahead on affordability. His first handful of executive orders moved to take action on the housing crisis, including a new Mayor’s Office to Protect Tenants and a pair of task forces that will review sites for development and identify policies for timely production and availability.

“For too long in our city, freedom has belonged only to those who can afford to buy it. Our City Hall will change that,” Mamdani promised on Thursday.

Mamdani Undoes Eric Adams’s Actions

In one of Mamdani’s first moves as mayor, he issued an order to undo directives signed by former Mayor Eric Adams since September 2024, when Adams was indicted by a federal grand jury on corruption charges.

“That was a date that marked a moment when many New Yorkers decided politics held nothing for them,” he told reporters.

Among them were a pair of Israel-related orders signed by Adams, an outspoken Israel ally who suggested last year that Jewish New Yorkers should be “concerned” in a Mamdani-led New York.

Mamdani, who is Muslim, has criticized the Israeli government but rejected accusations of antisemitism and pledged to support the Jewish community in New York, the largest outside of Israel.

He made a point at his inauguration to thank his predecessor, who was in attendance, even as he acknowledged their differences and campaign trail rivalry.

“[Adams] and I have had our share of disagreements, but I will always be touched that he chose me as the mayoral candidate that he would most want to be trapped with on an elevator,” Mamdani said, prompting laughter with the reference to Adams’s remarks in a podcast appearance last year.

Mamdani Leans Into Progressive Bona Fides

Mamdani leaned hard into his progressive bona fides as he promised a new era of politics in the city.

“To those who insist the era of big government is over, hear me when I say this: no longer will City Hall hesitate to use its power to improve New Yorkers’ lives. For too long, we have turned to the private sector for greatness while accepting mediocrity from those who serve the public,” Mamdani said.

He vowed that his office would “draw this city together” and “replace the frigidity of rugged individualism with the warmth of collectivism.” And he reiterated his aims to tax the wealthy to deliver on promises like universal childcare.

In the audience were top leaders of the progressive movement who had championed him along the campaign trail.

Rep. Alexandria Ocasio-Cortez (D-N.Y.) gave the opening remarks, in which she called the ceremony “an inauguration for each one of us” and lauded New Yorkers for choosing “historic, ambitious leadership.”

And Sen. Bernie Sanders (I-Vt.) led Mamdani’s swearing-in on the steps of City Hall after he thanked the audience for “inspiring our nation” by electing Mamdani. In his own remarks, Mamdani described Sanders as “the man whose leadership I seek most to emulate.”

Mamdani underscored that his popular though polarizing plans will not soften now that he’s in office.

“I was elected as a democratic socialist and I will govern as a democratic socialist,” he vowed.

Mamdani Stresses Unity

Mamdani’s rapid climb to political stardom rallied voters in and out of the Big Apple, but his ascent also had a deeply polarizing effect.

President Trump labeled him a “communist” before a more positive meeting at the White House this year, and the Republicans’ House campaign arm has attempted to paint him as a “socialist boss” of the Democratic Party. He’s also received criticism over his pro-Palestine positions and even earned a call-out from Israel’s Foreign Ministry for his orders on day one.

But Mamdani emphasized in his inauguration speech that he would embrace dissent and work with all sides to build a more unified New York.

“I stand alongside over 1 million New Yorkers who voted for this day nearly two months ago. And I stand just as resolutely alongside those who did not,” Mamdani said.

“I know there are some who view this administration with distrust or disdain, or who see politics as permanently broken. And while only action can change minds, I promise you this: if you are a New Yorker, I am your mayor. Regardless of whether we agree, I will protect you.”

Mamdani Makes History

Mamdani’s inauguration makes him the first Muslim and first South Asian person to serve as New York City mayor. And at 34, Mamdani also becomes the city’s youngest mayor in a century.

He took the oath during a private ceremony at an abandoned subway station near City Hall just after the ball dropped at midnight, and again publicly with Sanders, using three different Qurans. It marks the first time a NYC mayor used the Islamic holy text for the ceremony.

For the first ceremony, he used his grandfather’s Quran and another from the New York Public Library’s Schomburg Center for Research in Black Culture, according to The Associated Press. For the subsequent event, he used his grandfather’s and grandmother’s.

“To live in New York, to love New York, is to know that we are the stewards of something without equal in our world,” Mamdani said. “Where else could a Muslim kid like me grow up eating bagels and lox every Sunday?”
