The Koh-i-Noor and the Empire That Still Refuses to Let Go
When New York City Mayor Zohran Mamdani recently stated that he would urge King Charles III to return the Koh-i-Noor diamond to India, he reignited a long-standing debate about colonial plunder and historical justice. During the British monarch’s visit to the United States, Mamdani mentioned that if he had a private conversation with the King, he would likely ask him to “return the Koh-i-Noor Diamond.” His statement quickly spread across newspapers, television segments, and social media platforms because the Koh-i-Noor is more than just a jewel. It stands as a prominent symbol of Britain’s imperial conquest of the Indian subcontinent.
For many generations, Indians have seen Britain’s possession of the diamond as a reminder of colonial exploitation, humiliation, and force. The Indian government has consistently sought the return of the Koh-i-Noor, referring to it as a “valued piece of art with strong roots in our nation’s history.” However, the British establishment has shown little interest in revisiting this issue. In 2013, former British prime minister David Cameron rejected the notion of returning the gem, claiming it would not be “sensible,” adding that if Britain started returning disputed artifacts, “the British Museum would be empty.”
Cameron’s remark revealed more than he may have intended. It highlighted how deeply colonial acquisitions are still part of Britain’s identity. Yet, the story of the Koh-i-Noor is not a simple narrative of one nation stealing from another. It represents a centuries-long journey through conquest, betrayal, empire, exile, and memory. The diamond passed through Mughal courts, Persian invasions, Afghan dynasties, and the Sikh Empire before becoming part of the British Crown Jewels. Each ruler who owned it treated it as a symbol of power. Every empire that possessed it understood that the diamond signified more than just wealth.
At the heart of the modern debate is one undeniable historical fact: the British acquired the Koh-i-Noor from Maharaja Duleep Singh, the last ruler of the Sikh Empire, when he was only ten years old.
A Diamond Born in the Rivers of India
Long before it became a colonial trophy in London, the Koh-i-Noor originated from the alluvial diamond mines of the Indian subcontinent. Historians typically trace its roots to the Kollur mines in present-day Andhra Pradesh, although legends about the diamond go much further back. Some traditions link it to ancient Sanskrit tales and the Syamantaka jewel associated with Krishna, while others connect it to the treasures of medieval Indian kingdoms.
India used to be the primary source of diamonds in the world. For centuries, gemstones were not just decorative pieces in the subcontinent; they served as tools of political authority, spiritual significance, and royal legitimacy. In many Indian courts, jewels symbolized a visible hierarchy of power. Kings, nobles, and courtiers displayed gemstones based on strict codes reflecting status and rank.
The Koh-i-Noor first entered imperial history during the Mughal era. In 1526, Central Asian ruler Babur, the founder of the Mughal Empire, invaded northern India and established its reign. Over time, the Mughals amassed significant wealth through conquest, taxation, and tribute, transforming their courts into dazzling centers of art and luxury.
The diamond becomes identifiable in historical records during the reign of Mughal emperor Shah Jahan, who built the Taj Mahal. Shah Jahan commissioned the famous Peacock Throne in the seventeenth century, an opulent masterpiece adorned with emeralds, pearls, rubies, and diamonds. The Koh-i-Noor was prominently mounted on the throne, alongside another renowned gem, the Timur Ruby.
The Peacock Throne served not just as furniture but as a display of imperial power. It was designed to evoke the throne of the biblical King Solomon, linking Mughal rule to divine kingship. Court chroniclers described gem-studded peacocks, trees made of precious stones, and pillars decorated with emeralds. At the center of this spectacle sat the emperor himself.
For nearly a century, the Mughal Empire remained one of the wealthiest powers in the world. Delhi rivaled or surpassed European capitals in terms of wealth and population. But prosperity attracted invasion.
Nader Shah and the Sack of Delhi
In 1739, Persian ruler Nader Shah invaded Delhi in one of the bloodiest episodes in the city’s history. His forces killed thousands and emptied the Mughal treasury. Contemporary accounts describe caravans of loot so immense that hundreds of elephants, thousands of camels, and countless horses were needed to transport it back to Persia.
Nader Shah seized the Peacock Throne itself. According to popular accounts, he is responsible for giving the diamond its now-famous Persian name: Koh-i-Noor, meaning “Mountain of Light.” Whether this story is entirely accurate or not, the name persisted.
After Nader Shah’s assassination, the diamond traveled through the unstable political landscapes of Persia and Afghanistan. It changed hands amid coups, betrayals, and civil wars. Blinding, imprisonment, and executions accompanied many of these transfers. The Koh-i-Noor gained a reputation for misfortune and a curse, especially for male rulers who owned it.
While the diamond moved westward and northward, political power in India underwent drastic changes. The Mughal Empire was disintegrating, and regional powers were emerging. Meanwhile, a British trading company was gradually evolving into a military empire.
The Rise of the Sikh Empire
By the early nineteenth century, the diamond had returned to India and fell into the hands of Maharaja Ranjit Singh, the founder of the Sikh Empire.
Ranjit Singh was among the most formidable rulers India produced in the nineteenth century. Under his rule, the Sikh Empire expanded across Punjab and into parts of present-day Pakistan and Afghanistan. Lahore became a thriving imperial capital. Unlike the declining Mughal state and the expanding British East India Company, the Sikh Empire represented a native political force capable of resisting colonial control.
For Ranjit Singh, the Koh-i-Noor was not just a gem. It was a political symbol. Recovering it from Afghan ruler Shah Shuja represented the reversal of previous invasions into India. The diamond became linked with Sikh sovereignty and Punjabi pride.
Accounts from that period indicate that Ranjit Singh wore the Koh-i-Noor publicly and regarded it as a visible emblem of kingship. However, the Maharaja’s death in 1839 led to instability within the Sikh Empire. Succession struggles, assassinations, and factional rivalries weakened the state.
Within a decade, the British East India Company had decisively moved against Punjab.
The Child Maharaja and the British Annexation
The modern story of the Koh-i-Noor starts with a child. After the assassinations and deaths that followed Ranjit Singh’s reign, the Sikh throne eventually went to his youngest son, Maharaja Duleep Singh. He was the last Maharaja of the Sikh empire. At the time of the British victory over the Sikh Empire in the Anglo-Sikh Wars, he was just a boy.
In 1849, the British East India Company formally annexed Punjab. The Treaty of Lahore forced the surrender of the kingdom and required the Koh-i-Noor to be given to Queen Victoria. The crucial detail often hidden in legal jargon is that Duleep Singh was only ten years old.
He had already been separated from his mother, Maharani Jind Kaur, who the British considered politically dangerous. They imprisoned her and later exiled her. The young ruler was isolated, surrounded by British officials and stripped of any political power.
British accounts described the transfer of the diamond as a formal surrender due to treaty obligations. However, many historians argue that calling the handover voluntary strains credulity. A colonized child monarch, under military occupation and separated from his mother, signed away not just a diamond but an empire.
Even in Britain, some people recognized the moral issues around the acquisition. Duleep Singh himself became one of the most tragic figures of the British Empire. Taken to Britain, converted to Christianity, and made a favored aristocratic exile under Queen Victoria, he spent much of his adult life grappling with questions of identity, loss, and betrayal. As an adult, he tried but failed to reconnect with Sikhism and reclaim parts of his heritage.
Meanwhile, the Koh-i-Noor became a symbol of imperial propaganda.
When the diamond arrived in Britain, it was shown as a sign of imperial victory. The Queen received it with great fanfare. The Koh-i-Noor was displayed at the Great Exhibition of 1851 in London, where crowds lined up to see the famous jewel from India. Many visitors, however, found it surprisingly dull. Unlike modern brilliant-cut diamonds, the original Koh-i-Noor had a flatter Mughal cut that didn’t meet European standards for sparkle.
Prince Albert ordered the diamond to be recut by European jewellers. The process significantly reduced its size, from around 186 carats to just over 105 carats, while also changing its brilliance to fit Victorian tastes.
This transformation was symbolic in many ways. The British Empire had not only taken the diamond but also reshaped it. Over time, the Koh-i-Noor became a part of the British Crown Jewels. It appeared in the crowns of Queen Alexandra, Queen Mary, and eventually the Queen Mother. During her funeral in 2002, the crown containing the diamond sat atop her coffin, watched by millions around the world.
To many in Britain, the diamond became part of royal heritage. To many in South Asia, it remained stolen property.
The debate over the Koh-i-Noor cannot be separated from broader discussions about colonial theft. For decades, India has demanded the diamond's return. Governments from various political backgrounds have occasionally raised the issue diplomatically. Public sentiment in India is deeply emotional. The Koh-i-Noor is seen not merely as a gemstone, but as a reminder of the economic and cultural exploitation that came with colonial rule.
Yet the issue becomes more complex when asking a challenging question: if the diamond were returned, where should it go? India claims it because the diamond originated in the subcontinent and the British took it during the annexation of Punjab. Pakistan also claims it since Lahore, the capital of the Sikh Empire from which the British seized the gem, now lays within Pakistan.
Afghanistan has sometimes argued that the diamond belonged to Afghan rulers before Ranjit Singh acquired it. Iranian narratives occasionally link it to treasures taken by Nader Shah.
The history of the Koh-i-Noor reflects the shifting nature of pre-modern empires and borders. Modern nation-states often try to impose present political identities onto a past where boundaries were much less fixed. Still, one fact complicates the British defense the most: the final transfer happened under colonial occupation.
This is why comparisons with Nazi-looted art often come up in discussions about restitution. Historians like William Dalrymple and journalist Anita Anand argue that Britain cannot easily dismiss the ethical questions related to objects obtained during the empire. Their book ‘Koh-I-Noor’ challenged many myths that earlier British historians repeated. They showed how much of the accepted story of the Koh-i-Noor was shaped by imperial narratives meant to justify British possession.
For Dalrymple and Anand, the diamond’s history resembles an epic tale of conquest and bloodshed spanning centuries. Beneath the spectacle lies a critical modern question: what obligations do former colonial powers have toward items taken during occupation?
Despite increasing global discussions about restitution, Britain has consistently refused to return the Koh-i-Noor. British governments contend that the ownership issue is legally tricky and diplomatically sensitive. Officials worry that returning one well-known artifact could lead to demands for many other colonial items in British museums.
That concern was clear in David Cameron’s 2013 remarks against restitution. His statement that the British Museum would be empty if Britain started returning disputed objects reflected an imperial mindset that continues to influence museum politics in Europe.
At various times, the Indian government has seemed inconsistent. In 2016, during a case in the Indian Supreme Court, government lawyers initially claimed that the diamond was not stolen but rather “gifted” to the British under treaty terms. This statement caused outrage in India, leading the government to later clarify its commitment to bringing the Koh-i-Noor back.
Such contradictions highlight the challenges of navigating colonial history within current legal frameworks. Colonialism often operated through treaties signed under coercion. The language of legality doesn’t erase the realities of military occupation and imbalanced power.
Another aspect of the debate, often overlooked in mainstream Indian discussions, is the Sikh connection to the Koh-i-Noor. The diamond came specifically from the Sikh Empire. The last sovereign owner before British annexation was Duleep Singh, the son of Ranjit Singh. For many Sikhs, the Koh-i-Noor represents not just Indian heritage but Sikh political history.
This has led some Sikh scholars, activists, and commentators to argue that any discussions about restitution should recognize Punjab and the Sikh Empire, rather than viewing the diamond only as a national symbol of India. Historically, Lahore was the capital from which the Sikh Empire ruled. Today, Lahore is in Pakistan. This geographical reality complicates any simple nationalist claim.
There have also sometimes been discussions within Sikh circles about whether institutions connected to Sikh authority, like the Akaal Takht, should be involved in future talks about the Koh-i-Noor. However, no widely accepted or officially established claim from the Akal Takht exists demanding that the diamond be handed specifically to them.
The lack of a unified Sikh stance reflects broader complexities within Sikh political life. Yet the emotional connection is strong. For many Sikhs, seeing the Koh-i-Noor within the British Crown Jewels evokes not ancient India but the violent dismantling of the Sikh Empire and the humiliation of a child Maharaja.
The Curse of the Koh-i-Noor
Like many famous jewels, the Koh-i-Noor has gathered legends over time. One of the most enduring beliefs is that the diamond carries a curse for male rulers who wear it.
This myth likely arose from the violent histories associated with its ownership. Kings who owned the gem faced overthrow, assassination, imprisonment, or exile. By the time it arrived in Britain, stories spread that only women could safely wear the stone.
Whether it stems from superstition or political folklore, the myth adds to the allure of the diamond. But perhaps the true “curse” of the Koh-i-Noor is that it compels empires to confront uncomfortable memories.
The diamond represents the contradictions of imperial history. It is both a natural beauty, a piece of immense artistic heritage, and a trophy gained through conquest.
Britain often highlights the grandeur of the Crown Jewels while downplaying the violence that led to imperial wealth. The Koh-i-Noor disrupts that narrative. Its history cannot be recounted honestly without addressing annexation, coercion, and colonial extraction.
A Question Still Unresolved
The debate over the Koh-i-Noor is unlikely to end anytime soon.
As long as the diamond remains in the Tower of London, demands for restitution will continue to surface—from Indian politicians, Sikh activists, Pakistani commentators, Afghan claimants and anti-colonial scholars.
Zohran Mamdani’s recent remarks matter not because they suddenly changed British policy, but because they show how deeply the memory of empire continues to shape global politics even today. A century and a half after the annexation of Punjab, the story of the Koh-i-Noor still provokes anger, pride and unresolved grief.
And perhaps that is because the diamond is ultimately about more than ownership.
It asks whether colonial conquest can ever truly be separated from the treasures it produced.
It asks whether museums and royal collections should continue to display objects acquired under imperial domination without fully acknowledging the circumstances of their acquisition.
And if the Koh-i-Noor were ever returned, another difficult question would immediately arise.
Should it go to India, which sees it as part of the broader civilisational history of the subcontinent?
Should it go to Pakistan, since Lahore was the capital of the Sikh Empire from which the British seized it?
Should Sikhs, whose empire lost the diamond and whose child Maharaja was forced to surrender it, have the strongest moral claim?
Or has the history of conquest, transfer and empire become so layered that no modern state can claim uncontested ownership anymore?
For now, the Koh-i-Noor remains locked behind glass in Britain.
But the argument over who it truly belongs to is far from settled.
