Zohran Mamdani Is Inaugurated as New York City's 112th Mayor

Senator Bernie Sanders administered the public oath on the steps of City Hall, hours after Attorney General Letitia James swore Mamdani in at 12:01 a.m. in the disused City Hall subway station. He is the city's first Muslim mayor and the first of South Asian descent.

In his inaugural address Mamdani told New Yorkers "today begins a new era"^[1]
He first took the oath at 12:01 a.m. on 1 January 2026 in the old City Hall subway station, administered by Attorney General Letitia James, with his hand on a historic Qur'an from the Schomburg Center held by his wife, Rama Duwaji^[2]
His first act as mayor was to name Mike Flynn commissioner of the Department of Transportation^[2]
Public Advocate Jumaane Williams and new Comptroller Mark Levine were to be inaugurated at the same afternoon ceremony^[2]
At the public ceremony Bernie Sanders, a fellow democratic socialist, administered the oath as Rama Duwaji held the Qur'an^[5]
Mamdani told the crowd "I was elected as a democratic socialist, and I will govern as a democratic socialist", after speeches by Sanders and Rep. Alexandria Ocasio-Cortez^[3]
About 4,000 guests were invited, with a block party for everyone else in subfreezing weather^[4]; the city set up a viewing area along Broadway^[3]
Governor Kathy Hochul and former mayors Eric Adams and Bill de Blasio attended^[5]
