New York City Mayor Zohran Mamdani has called for the return of the historic Kohinoor diamond to India, saying he would urge Britain’s King Charles III to hand it back during his ongoing visit to the United States. He remarked on April 30, 2026, in New York City ahead of a ceremony commemorating the victims of the September 11 attacks.

Speaking to reporters, Mamdani clarified that the issue is not part of the official agenda, but added that he would raise it if allowed a private conversation with the British monarch. His comments have once again brought global attention to the long-standing demand for the return of the Kohinoor, one of the world’s most famous diamonds.

The Kohinoor, weighing 105.6 carats, originated in India and passed through several ruling dynasties before being taken by the British East India Company in 1849 under the Treaty of Lahore. It is now part of the British Crown Jewels and is displayed at the Tower of London, remaining a powerful symbol of colonial history.

India has long maintained that the diamond was taken under duress and has repeatedly sought its return, describing it as an important part of the country’s heritage. The United Kingdom, however, continues to assert legal ownership based on historical agreements. Mamdani’s remarks have once again reignited debate around cultural restitution and the legacy of colonial-era acquisitions.
