Zohran Mamdani was sworn in as mayor of New York City shortly after midnight on Thursday, in a brief private ceremony attended by a few dozen family members, friends and supporters.

Newly sworn-in New York City Mayor Zohran Mamdani has launched the Mayor’s Office of Mass Engagement to deepen civic participation and strengthen grassroots power in city governance.

Mamdani, a 34-year-old immigrant from Uganda, makes history as the city’s first Muslim mayor, first South Asian mayor and the youngest mayor to hold the high-profile office in more than a century.
