The Martial Heritage of the Sikh Community

The Sikh community is widely recognized for its deep-rooted martial heritage – a tradition that did not emerge overnight but was shaped over centuries through religious conviction, persistent conflict, and exceptional military leadership. From resisting Afghan invasions in the 18th century to fighting under the British flag on the Western Front in World War I, the Sikh martial identity is one of the most remarkable stories of warrior culture in modern history.

The religious roots of Sikh martial identity

To understand the Sikh martial background, it is essential to start with its spiritual foundations. Sikhism was not always a warrior faith. Its founder, Guru Nanak, emphasized equality, humility, and devotion. The shift toward an armed identity came gradually, driven by political necessity rather than religious aggression.

The turning point came in the early 17th century. After the Mughal emperor Jahangir had the fifth Guru, Arjan Dev, executed in 1606, his successor – Guru Hargobind – added the martial dimension to Sikhism, recruiting an army and training followers in cavalry and Sikh martial arts. He adopted the twin swords of Miri and Piri, representing temporal and spiritual authority, signaling that Sikhs would now defend their faith with force.

The most decisive transformation came in 1699, when the tenth Guru, Guru Gobind Singh, founded the Khalsa – a community of initiated Sikhs with a duty to protect the innocent from religious persecution. Members of the Khalsa were given a distinct identity through the Five Ks: Kesh (uncut hair), Kara (iron bracelet), Kirpan (sacred sword), Kangha (wooden comb), and Kachhera (special shorts). Every male Sikh adopted the name “Singh” (meaning lion), symbolizing courage. Guru Gobind Singh gave the Sikhs the organization and discipline to succeed as saint-warriors – individuals who balanced spiritual devotion with the readiness to fight for justice.

Crucially, the warrior ethos of Sikhism was never about conquest. The warrior ethos was rooted in the defense of righteousness and justice, not in aggression. This philosophy of the Sant-Sipahi (saint-soldier) became central to how Sikhs understood their role in the world.

The Afghan threat and the forging of a martial nation

By the 18th century, the Punjab region had become a battleground. After the decline of the Mughal Empire, the biggest menace to a united and free Punjab came from the Afghans. Since Ahmad Shah Abdali’s campaigns beginning in 1752, Afghan rulers had regarded most of northern India, including the Punjab, as part of their domain. They launched repeated invasions, disrupting Sikh-controlled territories and plundering cities including Amritsar.

The Sikhs, organized into armed confederacies called Misls, resisted wave after wave of these incursions. After Ahmad Shah’s final invasion of the Punjab in 1767, he left Lahore, which was recaptured by the Sikhs. For over three decades afterward, the Sikhs worked to consolidate power across the region, even while facing continued invasion attempts from later Afghan rulers like Timur Shah Durrani and Zaman Shah Durrani. These relentless conflicts did not weaken the Sikhs – they strengthened their collective identity and hardened their martial resolve.

Maharaja Ranjit Singh: the architect of the Sikh Empire

The scattered energy of the Sikh Misls found its unifying force in one extraordinary leader: Maharaja Ranjit Singh (1780-1839). Born in Gujranwala and raised in the tradition of Sikh martial valor, he succeeded his father as leader of the Sukerchakia Misl at the age of twelve. By the time he was a young adult, he had already begun consolidating fractious Sikh factions under his command.

In 1799, Ranjit Singh captured Lahore, the historic capital of the Punjab. He was the first Indian in a millennium to turn the tide of invasion back into the homelands of the traditional conquerors of India, the Pashtuns (Afghans), earning him the title Sher-e-Punjab – the Lion of the Punjab. In 1801, he proclaimed himself Maharaja of Punjab, and within just over a decade had unified the major Sikh Misls under centralized authority.

His military campaigns against Afghan forces were defining episodes of the era. The most significant encounters between the Sikhs under the Maharaja and the Afghans came in 1813, 1823, 1834, and 1837. Each confrontation pushed Afghan influence further back. By 1818, Afghan control over Multan had ended. By 1819, Ranjit Singh had defeated Afghan rulers and annexed the Kashmir valley. In 1834, he repulsed a 25,000-strong Afghan force that had marched on Peshawar under the banner of jihad. The Battle of Jamrud in 1837 marked the last major Afghan confrontation of his reign, cementing the western boundaries of the Sikh Empire at the Khyber Pass.

Building a modern army

Ranjit Singh’s genius was not just in battlefield courage but in institutional military reform. In 1820, Ranjit Singh began to modernize his army, using European officers – many of whom had served in the army of Napoleon I – to train the infantry and the artillery. His reorganized force combined the fierce irregular cavalry of the Nihangs (traditional Sikh warriors) with disciplined, European-trained infantry and a formidable artillery corps. French, British, and other foreign veterans were enlisted to bring technical expertise, while the Khalsa spirit provided the moral and cultural backbone of the force.

At its zenith, Ranjit Singh’s reorganized army kept at bay any British, Afghan, or Russian threat for four decades, consolidating a rich empire roughly the size of modern-day Germany. His approach was notably inclusive: all his conquests were achieved by Punjabi armies composed of Sikhs, Muslims, and Hindus, and his commanders and ministers were drawn from multiple religious communities. This multicultural statecraft, combined with the Khalsa’s martial backbone, made the Sikh Empire one of the most formidable powers on the Indian subcontinent.

The collapse of the empire and British annexation

After Ranjit Singh’s death in 1839, internal divisions weakened the empire. After the death of Maharaja Ranjit Singh, the empire was weakened by the British East India Company stoking internal divisions and political mismanagement. The two Anglo-Sikh Wars of 1845-46 and 1848-49 ended with British annexation of the Punjab – making it the last kingdom in India to be taken over by the British. However, the British did not simply dismantle the Sikh military tradition – they eventually co-opted it.

Sikhs and the British army: from adversaries to allies

Following annexation, the British disbanded the old Sikh army and confiscated over 120,000 weapons. Yet they quickly recognized the military value of the Sikh soldier. The colonial doctrine of “martial races” – a contested but operationally influential British theory – cultivated Punjabis as a “loyal military race”, and Sikh recruitment into the British Indian Army expanded steadily through the latter half of the 19th century.

The Battle of Saragarhi in 1897 became a defining symbol of this Sikh military legacy under British command. 21 soldiers of the 36th Sikhs fought against 6,000-10,000 Pashtun tribesmen in what military historians regard as one of the greatest last stands in history. All 21 soldiers chose to fight to the death rather than surrender. Each was posthumously awarded the Indian Order of Merit – the equivalent of the Victoria Cross.

World War I: the Sikh contribution on the global stage

When war broke out in Europe in 1914, Sikh soldiers were among the first Indian troops to reach the Western Front. Their contribution to the British war effort was extraordinary – both in scale and in sacrifice.

At the beginning of the war, Sikh military personnel numbered around 35,000 men of the 161,000 troops of the Indian Army – approximately 22% of the armed forces, despite Sikhs making up less than 2% of the total Indian population. By the end of the conflict, 100,000 Sikh volunteers had joined the British Armed Forces, with some even serving in the French Air Service and the American Expeditionary Force.

Over 138,000 Indian troops fought in Belgium and France, many of them Sikh, and more than one-quarter became casualties. At the Battle of Neuve Chapelle in March 1915, Sikh regiments suffered catastrophic losses – some standing at only 16% of their original strength by the battle’s end. In the Gallipoli campaign, the 14th Sikh regiment lost 379 officers and men in a single day’s fighting on 4 June 1915, with casualties reaching 82% of all men engaged that day.

Fighting under the turban, not the helmet

What made the Sikh presence on the battlefield particularly striking was that these soldiers fought without steel helmets – their religious identity required them to wear the turban. The British found it necessary to allow Sikhs to set up temporary Gurdwaras, observe the birthdays of Sikh Gurus, and use traditional weapons such as Sikh quoits and the sabre. The Sikh Holy Scripture was sometimes carried before marching battalions and even onto the front lines. Faith and martial duty were inseparable.

Known as the “Black Lions” by Arab forces in Mesopotamia, Sikh soldiers became a byword for fearlessness. One soldier, Indar Singh, wrote from the Somme in 1916 that he expected to die but saw it as a warrior’s death – approaching martyrdom in an almost religious spirit, as dying in the warrior’s clothes. Across both World Wars, 83,005 Sikh soldiers gave their lives, and 109,045 were wounded – a sacrifice that remains a defining chapter in the history of the British armed forces.

A legacy written in valor

The martial heritage of the Sikh community is not simply a historical footnote. It is a thread woven through the community’s religious identity, political history, and collective memory. From Guru Gobind Singh’s founding of the Khalsa in 1699, through the wars of Maharaja Ranjit Singh against Afghan invaders, to the trenches of the Western Front and the shores of Gallipoli, the Sikh warrior tradition has demonstrated a consistent ethic: fighting not for conquest, but for justice, honor, and the protection of the vulnerable.

The Sikh Regiment of the Indian Army is today the most highly decorated regiment in the Indian Army, and Sikh soldiers continue to serve in armed forces around the world. The tradition Maharaja Ranjit Singh built, and that thousands of nameless soldiers carried into two world wars, endures.

What do you think? How much does a community’s historical experience of conflict shape its collective identity over generations? And does the concept of the saint-soldier – combining spiritual devotion with a duty to fight for justice – offer a model that is still relevant in the modern world?
