New York City Mayor Zohran Mamdani has publicly encouraged King Charles III to return the Koh-i-Noor diamond, a controversial jewel that has been at the center of debates over colonial artifacts. The request was made during the King's visit to New York City on Wednesday, April 29, 2026, as part of his U.S. state visit.
The Koh-i-Noor Diamond's Controversial History
The Koh-i-Noor diamond, which means "Mountain of Light" in Persian, is one of the largest cut diamonds in the world. It was originally mined in India and has passed through the hands of various rulers, including the Mughals, Persians, Afghans, and Sikhs. The British East India Company seized the diamond in 1849 during the annexation of the Sikh Empire, and it was later presented to Queen Victoria. Since then, it has been part of the British Crown Jewels, currently set in the Crown of Queen Elizabeth The Queen Mother.
Several countries, including India, Pakistan, Afghanistan, and Iran, have claimed ownership of the diamond, arguing that it was taken illegally during the colonial era. The British government, however, maintains that the diamond was acquired legally and has refused to return it.
Mayor Mamdani's Remarks
During a joint appearance at the 9/11 Memorial, Mayor Mamdani, whose parents immigrated from India, directly addressed King Charles, saying, "Your Majesty, I hope you will consider returning the Koh-i-Noor diamond to its rightful home. It is a symbol of colonial exploitation and a reminder of the injustices of the past." The King listened attentively but did not offer a public response.
The mayor's comments have reignited the global debate over the repatriation of cultural artifacts. Many activists and historians support the return of the diamond, while others argue that it is part of British heritage and should remain in the United Kingdom.
King Charles's Visit
King Charles and Queen Camilla are on a multi-day state visit to the United States, which includes meetings with President Donald Trump and First Lady Melania Trump. The visit has been marked by both ceremonial events and discussions on bilateral issues. The King's schedule also includes a farewell event with the Trumps on the last day of the visit.
The Koh-i-Noor diamond is not the only controversial artifact in the British Crown Jewels. Other items, such as the Cullinan diamonds, have also been subject to claims for repatriation. However, the British government has consistently resisted these demands, citing legal and historical reasons.
Mayor Mamdani, a progressive politician known for his advocacy on social justice issues, has previously called for the return of other colonial artifacts. His latest comments are likely to intensify the pressure on the British monarchy and government to address the issue.
