India’s engagement with terrorism stretches back to the colonial period, long before the nation gained independence in 1947. Understanding this historical journey is essential to grasping the complex nature of terrorism that the country continues to face today. From politically motivated violence during British rule to contemporary challenges across different regions, the origins and evolution of terrorism in India reveal a multifaceted problem shaped by political, ethnic, religious, and socioeconomic factors.

Terrorism under British rule: the genesis
The roots of political violence in India can be traced to the early twentieth century when groups of educated, middle-class revolutionaries began using violent methods to challenge British colonial authority. These individuals, whom the British termed “gentleman terrorists” due to their high caste status and education, planted bombs, conducted assassinations, and attacked British officials and infrastructure. Inspired by revolutionary movements in Russia, France, America, and Ireland, these activists believed that immediate armed resistance was necessary to end colonial rule.
The violent nationalist movement included organizations like the Anushilan Samiti and Yugantar, which operated primarily in Bengal. Notable incidents include the Chittagong Armory Raid of 1930, modeled after the Irish Easter Rising, which sparked renewed terrorist activity. The British responded with stringent anti-terrorism legislation, indefinite detention powers, and detention camps, which created significant controversy both internationally and within India.
These revolutionary terrorists maintained complex relationships with the broader independence movement. Although Mahatma Gandhi and the Indian National Congress officially disavowed violence, they utilized the detention and martyrdom of these revolutionaries to mobilize resistance against the British. Gandhi himself acknowledged that while he disagreed with their methods, he viewed them as committed patriots.
Post-independence terrorism: new forms emerge
After independence in 1947, terrorism in India evolved into several distinct forms based on different motivations and regional contexts. The Ministry of Home Affairs identifies terrorism as a significant threat, with India facing a wider range of terror groups than most countries. The three primary categories include Islamist terrorism, ultranationalist terrorism, and left-wing terrorism.
Politico-ethnic terrorism in the Northeast
The northeastern states have experienced sustained insurgency since the 1950s, driven primarily by ethnic identity and demands for autonomy or independence. Organizations like the United Liberation Front of Asom (ULFA), formed in 1979, sought to establish a sovereign state for indigenous Assamese people. The National Socialist Council of Nagaland (NSCN), emerging from the Naga nationalist movement, has fought for Naga independence since the 1940s.
These insurgent groups have maintained extensive cross-border networks, establishing training camps in neighboring Myanmar, Bangladesh, and Bhutan. The ULFA maintained contact with Pakistani intelligence and received arms from Thailand and Cambodia through complex trafficking networks. Multiple insurgent groups formed alliances, with ULFA and NSCN coordinating logistics and training since the 1980s.
The northeastern insurgency has claimed approximately 20,000 lives since the 1950s, with civilians accounting for roughly 40 percent of fatalities. However, recent years have seen significant decline, with a 70 percent reduction in insurgency incidents and an 80 percent drop in civilian deaths between 2013 and 2019.
Politico-religious terrorism in Kashmir
The Kashmir insurgency began in 1989, rooted in longstanding territorial disputes between India and Pakistan dating back to partition. Islamic separatist groups like Hizbul Mujahideen, Lashkar-e-Taiba, and Jaish-e-Mohammed have carried out attacks seeking either independence or merger with Pakistan. The insurgency transformed over time from externally supported militancy to a more domestically driven movement, though cross-border support continues.
Pakistan’s Inter-Services Intelligence (ISI) has played a controversial role, with reports alleging active support for militant groups operating in Kashmir. While Pakistan officially ended support for insurgents in 2004 and labeled them terrorists, questions remain about the ISI’s activities. Major attacks like the 2016 Uri attack and the 2019 Pulwama attack demonstrated the continuing threat, while the 2025 Pahalgam attack killed 26 civilians.
Socioeconomic terrorism: the Naxalite movement
Left-wing extremism, commonly known as the Naxalite or Maoist insurgency, originated in 1967 with an uprising in Naxalbari, West Bengal. Led by activists inspired by Maoist ideology, the movement advocated for violent revolution to overthrow existing socioeconomic structures and fight exploitation of marginalized tribal and rural communities.
The Communist Party of India (Maoist), formed in 2004 through the merger of two major factions, became India’s largest armed group operating internally. Former Prime Minister Manmohan Singh called it the single biggest internal security threat facing the country. The insurgency has been most active in central and eastern states including Chhattisgarh, Jharkhand, Odisha, Andhra Pradesh, and Bihar, areas rich in mineral resources but characterized by underdevelopment and tribal populations.
Between 2000 and 2025, the conflict resulted in more than 12,000 deaths, including over 4,000 civilians, 2,700 security personnel, and nearly 5,000 Naxalites. The Naxalites have employed guerrilla warfare tactics, targeting local officials, police stations, and infrastructure to create governance vacuums. However, the movement has seen significant decline in recent years, with the affected area shrinking from nearly 180 districts in the late 2000s to just 12 districts by 2025.
External linkages and transnational dimensions
A significant complexity in Indian terrorism involves external support networks. Pakistani intelligence agencies have been repeatedly accused of supporting various terrorist groups operating in India, from Kashmir to the Northeast. Chinese intelligence services have also been implicated in providing weapons and training to northeastern insurgent groups through intermediaries in Myanmar.
Arms trafficking routes typically run from Southeast Asian markets through Myanmar and Bangladesh into India’s northeastern corridor. The ISI has reportedly facilitated arms shipments from Cambodia through Bangladesh to insurgent groups in Tripura, Assam, and Manipur. These international dimensions make addressing terrorism particularly challenging for Indian security forces.
The multifaceted challenge
The diverse origins of terrorism in India create unique challenges for counterterrorism efforts. In the Northeast, ethnic identity and demands for autonomy drive insurgency. In Kashmir, religious identity and territorial disputes fuel separatist violence. In central India, socioeconomic marginalization and tribal exploitation underpin Maoist insurgency. Each requires different approaches beyond purely military solutions.
The Indian government has employed varied strategies including security operations, peace accords, development initiatives, and political dialogue. Notable successes include the Mizo Peace Accord (1986), which ended insurgency in Mizoram, and the Bodo Peace Accord (2020), which led to the surrender of over 1,500 militants. However, addressing root causes such as economic underdevelopment, political alienation, and social exclusion remains essential for sustainable peace.
What do you think? How can India balance security measures with addressing the underlying socioeconomic and political grievances that fuel different forms of terrorism? What role should development and inclusive governance play alongside military approaches in counterterrorism strategy?
