New York City Mayor Zohran Mamdani’s four-term term leading the nation’s largest city begins Jan. 1 with a seven-block long street party and guest appearances at his inaugural ceremony from the leading lights of the left.

The 34-year-old democratic socialist will be sworn in outside City Hall by Sen. Bernie Sanders after an introduction by Rep. Alexandria Ocasio-Cortez.

Mamdani is the 112th person — but the first Muslim and the first person of South Asian descent — to lead the nation's largest city.

In 2025, Mamdani stunned political establishment by defeating former Gov. Andrew Cuomo first in the Democratic primary and again in the November general election. He ran on a progressive platform to address affordability, reshaping a mayor’s race that resonated even in the White House with Republican President Donald Trump.

Mamdani takes over from scandal-scarred Mayor Eric Adams whose one-term administration became mired in corruption scandals.
