Zohran Mamdani’s Historic Election and the Hidden Number Behind It

When 34-year-old Zohran Mamdani won the New York City mayoral race last month, he didn’t just claim an office. He marked a turning point in the city’s political history. Born in Kampala, Uganda, and raised in Queens, Mamdani will become the first Muslim, the first South Asian, and the first Africa-born mayor of New York. His victory reflects a city evolving while staying true to its global roots.

Mamdani is scheduled to be sworn in as New York’s 111th mayor in January 2026. However, recent archival research suggests he may actually be the 112th.

A Historian’s Quiet Discovery

While studying early colonial governance, historian Paul Hortenstine found a centuries-old counting error hidden in the city’s records. He discovered that Matthias Nicolls, officially listed as the sixth mayor, served two non-consecutive terms—in 1672 and 1675.

Today, such split tenures are counted separately, just as Grover Cleveland is considered both the 22nd and 24th U.S. president. Yet, Nicolls’s second term was never listed as a separate administration. According to Hortenstine, this single oversight caused every subsequent mayor to be misnumbered by one.

Hortenstine traced the mistake to a misinterpreted 17th-century Dutch-English translation in an archival ledger. He has since contacted the mayor’s office to share his findings.

An Echo From the Past

This isn’t a new concern. In 1989, historian Peter R. Christoph raised similar questions about mayoral numbering. At the time, officials ignored the discrepancy. Civic traditions simply continued, uncorrected.

The new evidence doesn’t affect Mamdani’s authority or legitimacy. It only changes the ceremonial numbering. Yet, the historical irony is striking: a milestone election paired with a centuries-old footnote.

A City Built on Layers

Whether the city will officially update its records remains uncertain. Revising them would require changing public archives, plaques, and numerous databases. Yet for many, the revelation feels symbolic.

Mamdani’s election itself rewrites who belongs in New York’s story of power. In a city layered with immigrant stories, erased names, and forgotten records, even a misplaced number tells a truth: history is fluid. It bends, corrects, and reveals itself anew.

As Mamdani prepares to take office, this 17th-century footnote reminds New Yorkers: leadership and history are strongest when they face the past without fear.
