In a historic ceremony that marks a significant political shift, Zohran Mamdani was sworn in as the 110th mayor of New York City on Thursday, promising to usher in a "new era" for America's largest metropolis. The 34-year-old democratic socialist, flanked by high-profile allies, immediately set an ambitious tone for his administration.
A Historic Inauguration and a Defiant Pledge
The day began with a symbolic midnight swearing-in at a disused subway station, where Mamdani was flanked by New York Attorney General Letitia James and his wife, 28-year-old animator Rama Duwaji. The formal ceremony later on the steps of City Hall, on a bitterly cold January day, was introduced by Congresswoman Alexandria Ocasio-Cortez and saw Senator Bernie Sanders administer the oath of office.
Mamdani made history on multiple fronts: he is New York City's first Muslim mayor, the first of South Asian descent, and the first to be born in Africa. In another first, he took his oath of office on the Qur'an, held by his wife.
In his inaugural address, Mamdani defiantly embraced his political ideology. "I was elected as a democratic socialist and I will govern as a democratic socialist," he declared to loud cheers. "I will not abandon my principles for fear of being called radical." He rejected advice to lower expectations, vowing instead to "govern expansively and audaciously."
The Political Backing and the Policy Agenda
The presence of Sanders and Ocasio-Cortez underscored the progressive coalition that propelled Mamdani from a relatively unknown state assemblyman to mayor in just one year. Ocasio-Cortez praised the choice of "courage over fear" and "prosperity for the many over spoils for the few."
Senator Sanders, whose 2016 presidential campaign helped popularise the affordability agenda Mamdani now champions, said the new mayor was taking power "at a time when we are seeing too much hatred, too much divisiveness and too much injustice." He hailed Mamdani's victory over political establishments and "enormously wealthy oligarchs" as "the biggest political upset in modern American history."
Mamdani's platform is notably ambitious, centring on economic rights and affordability. His key pledges include:
- Free childcare for city residents.
- Free bus services across the five boroughs.
- A rent freeze for approximately one million households.
- A pilot programme for city-run grocery stores.
To fund these services, estimated to cost around $10 billion, Mamdani has vowed to raise taxes on the wealthiest New Yorkers and increase corporate taxes.
Immediate Challenges and Controversies
The new mayor faces a formidable array of challenges. As a vassal of the New York state government, he will require legislative support from Governor Kathy Hochul, who is running for re-election next year. He must also navigate a relationship with former President Donald Trump, who has labelled him a "communist" and threatened to withhold federal funding, despite a surprisingly cordial recent meeting.
Mamdani also confronts scepticism from some Jewish communities, alarmed by his past criticisms of Israel's government and his previous use of the phrase "from the river to the sea," which he has now pledged not to use. Tensions were highlighted during his transition when his director of appointments, Cat da Costa, resigned over antisemitic tweets, an error his team called "an unacceptable oversight."
In a move to ensure continuity, Mamdani has persuaded Police Commissioner Jessica Tisch to remain in her post. He inherits a city where crime, particularly homicides and shootings, has declined under outgoing Mayor Eric Adams, who reported 301 homicides in 2025—79 fewer than the previous year.
Ultimately, New York mayors are judged on basic services: trash collection, rat control, pothole repairs, and smooth subway operation. Mamdani and his wife will now trade their rent-stabilised one-bedroom apartment in Astoria, Queens, for the stately—and reportedly haunted—Gracie Mansion on Manhattan's Upper East Side.
As Mayor Adams warned him, the mansion's ghost is "friendly, as long as you’re doing right by the city." For millions of New Yorkers, the truth of that warning will be revealed in the ambitious and audacious governance Zohran Mamdani has just promised.
