New York Mayor Zohran Mamdani said the United Kingdom should return the Kohinoor diamond to India this week.

The request highlights a long-standing colonial dispute regarding the ownership of the gem. By aligning with India's claim, the mayor is bringing a global repatriation debate into the spotlight during a high-profile diplomatic event.

Mamdani said this ahead of King Charles III's state visit to the U.S. The visit is scheduled to last four days [1]. The mayor's message targets the British monarchy's continued possession of the diamond, which India maintains rightfully belongs to the Indian people [3].

The Kohinoor diamond has remained a point of contention between the two nations for decades. The gem is currently part of the British Crown Jewels, but India has frequently requested its return as a symbol of colonial restitution [3].

By addressing the issue during the royal visit, Mamdani is using the presence of the British monarch in New York City to amplify the demand for the diamond's return [1, 2]. The move connects the local administration's voice to a broader international movement seeking the repatriation of cultural artifacts taken during imperial rule [3].

The mayor's stance echoes official positions previously held by the Indian government. The call for the return of the Kohinoor is part of a larger trend where political leaders use diplomatic windows to press for the correction of historical grievances [3].

New York Mayor Zohran Mamdani called for the United Kingdom to return the Kohinoor diamond to India.

This action by Mayor Mamdani signals a shift where municipal leaders in the U.S. are increasingly engaging with international post-colonial disputes. By leveraging a state visit, the mayor is applying symbolic pressure on the UK to address repatriation claims, reflecting a growing global sentiment that cultural artifacts should be returned to their countries of origin.
