Refugee Influx in Northeast India: Historical Waves and Present Challenges

The Northeast has long sat at the receiving end of some of South Asia’s largest forced migrations. Long before “refugee crisis” became a global headline, states like Assam, Tripura, Mizoram, and Arunachal Pradesh were absorbing waves of displaced people fleeing violence, persecution, and even submerged homelands. These movements did not just add numbers to a census. They reshaped languages, redrew political battle lines, and triggered debates over citizenship that remain unresolved today. Understanding the refugee story of the Northeast means tracing a chain of events that runs from the Partition era right up to the deportations making news in 2025.

How Partition set the stage 🔗

The refugee story of the Northeast begins with the violence that preceded 1947. The earliest large movement of people into the region was triggered by the Noakhali riots of October 1946, when communal violence in the Noakhali and Tipperah districts of East Bengal targeted the Hindu minority. Around 50,000 people were displaced, and many survivors eventually crossed into West Bengal, Tripura, and Assam in the years after Partition.

These were communal riots that historians often describe as a kind of rehearsal for the horrors of Partition itself. When the subcontinent was formally divided in 1947 and East Bengal became part of Pakistan, the trickle became a flood. The creation of East Pakistan turned a porous internal frontier into an international border, and people who suddenly found themselves on the “wrong” side began moving.

Why the Northeast was different 🔗

The northeastern frontier posed a problem that the Punjab border did not. The boundary here ran through rivers, forests, and hills, following traditional migration routes that had connected these communities for generations. This made population movements extremely hard to monitor or stop. Unlike the well-resourced rehabilitation programmes set up in West Bengal, the northeastern states had to manage incoming refugees with thin infrastructure and limited funds.

The first significant influx into Assam came in October 1946 following Noakhali, and by May 1949 the number of refugees in Assam had climbed to over 2.7 lakh. This early friction between the indigenous Assamese population and Bengali Hindu refugees would set a pattern of resentment that recurs throughout this story.

The 1971 turning point 🔗

If Partition opened the door, the Bangladesh Liberation War of 1971 blew it off its hinges. When the Pakistani military launched a brutal crackdown in East Pakistan, an estimated ten million people fled across the border into India. The scale was staggering, and the Northeast bore a heavy share of it.

According to figures compiled at the time, nearly 9.9 million refugees sought shelter in India between March 1971 and the war’s end. Of these, Tripura alone received over 14 lakh, Meghalaya took in roughly 6.6 lakh, and Assam recorded over 3 lakh in its official camps. For a small state like Tripura, the refugee population at one point rivalled the size of its own residents, a demographic shock few regions anywhere have faced.

The refugees who stayed 🔗

Most of these refugees were expected to return home once Bangladesh became independent. Many did. But a significant portion stayed on. Estimates suggest that around 1.5 million East Bengali refugees remained in India after the war ended. In the Barak Valley of Assam, where around 400,000 refugees arrived between March and December 1971, the largest camp at Silchar alone sheltered more than 1.5 lakh people.

This is the crux of the demographic anxiety that came to dominate Assam’s politics. The migration substantially altered the cultural and demographic balance of regions like the Barak Valley, and the Assamese-speaking population began to fear that they would be reduced to a minority in their own state.

How Assam’s demographics changed everything 🔗

The numbers tell a story of slow but relentless transformation. Studies estimate that the Muslim immigrant population from East Pakistan and Bangladesh living in Assam between 1951 and 2001 may have been around 32.5 lakh, with the bulk of it arriving in the decades surrounding 1971. Layered on top of this were the Bengali Hindu refugees and a third, older stream of Bengalis brought in by the British for clerical and professional work.

The political consequences became impossible to ignore when Assam’s number of registered voters jumped dramatically from 6.3 million in 1972 to 8.7 million in 1979, a rise that could not be explained by new eligible voters alone. Many in Assam read this as evidence that undocumented migrants were quietly being enrolled, and that fear lit the fuse.

The Assam Movement and the Accord 🔗

Between 1979 and 1985, the All Assam Students’ Union led a sustained agitation demanding the detection, deletion, and deportation of illegal immigrants. The movement caused enormous social unrest and considerable violence. It finally ended with the Assam Accord of 1985, signed between the student leaders and the Rajiv Gandhi government. The Accord fixed a crucial cut-off date: anyone who entered Assam after March 24, 1971 would be treated as a foreigner and made liable for detection and expulsion. That single date continues to govern citizenship disputes in Assam decades later.

The Chakmas and Hajongs: refugees of a dam 🔗

Not every refugee group in the Northeast fled a riot or a war. The Chakmas and Hajongs were displaced by an engineering project. Originally residents of the Chittagong Hill Tracts of East Pakistan, these communities were uprooted in the 1960s when the Kaptai dam on the Karnaphuli River submerged their land. The Chakmas are mostly Buddhist and the Hajongs mostly Hindu, and both also reported religious persecution.

They entered India through the Lushai Hills district of Assam, which is now Mizoram. To avoid friction with the local population there, the central government resettled them in the sparsely populated areas of what was then the North East Frontier Agency, now Arunachal Pradesh. Around 14,888 were settled between 1964 and 1969 in relief camps in districts like Changlang.

Decades of contested belonging 🔗

What followed was a long battle over whether these settlers belonged. Until the 1980s, Chakmas and Hajongs could access ration cards, trading licences, and government support much like other residents. But in the 1990s their rights were stripped away and they were branded illegal migrants. The All Arunachal Pradesh Students’ Union spearheaded movements demanding their resettlement elsewhere, and in 1994 the community was even served “Quit Arunachal Pradesh” notices that triggered mass agitations.

The judiciary became their lifeline. In its 1996 judgment in the NHRC versus State of Arunachal Pradesh case, the Supreme Court protected the community, and in 2015 it directed the government to grant citizenship to eligible Chakmas. The proposed solution was a “limited citizenship” that withheld land ownership rights and Scheduled Tribe status, an attempt to balance the refugees’ rights against the fears of indigenous tribes like the Tangsa, Singpho, Khampti, Nocte, and Mishmi. The population had grown from the original settlers to around 65,000, and the underlying tension between settlement and indigenous identity has never fully eased.

The Rohingya: a refugee crisis without a refugee law 🔗

The most recent chapter involves the Rohingya, a stateless Muslim minority who fled genocidal violence in Myanmar’s Rakhine state, with the largest exodus occurring after 2017. An estimated 40,000 reached India, and roughly 22,500 are registered with the UNHCR. Their story exposes a fundamental gap in Indian policy: the country has never signed the 1951 Refugee Convention and has no domestic refugee law. As a result, the Rohingya are treated as foreigners under the Foreigners Act rather than as protected refugees.

The Northeast has also become a frontline for a separate Myanmar refugee flow. After the military coup of February 2021, Mizoram became the epicentre of refugee arrivals, with over 9,000 people from Myanmar crossing in during 2022 alone. Crucially, the Mizoram government chose to welcome and assist Chin refugees, who share ethnic roots with the Mizos, even though this defied directions from the central government to seal the borders.

A hardening stance 🔗

Government policy on the Rohingya has grown noticeably tougher. Human Rights Watch has reported that since May 2025, Indian authorities expelled scores of Rohingya refugees to Bangladesh and Myanmar, including some registered with the UNHCR, and detained several hundred more. Critics argue this violates the principle of non-refoulement, the idea that refugees should not be returned to places where they face grave danger. The government’s position is that the Rohingya are illegal immigrants who pose a security and resource burden, a framing that places humanitarian obligations and national security concerns in direct conflict.

The unfinished business of citizenship 🔗

All these waves eventually collide in the question of who counts as a citizen. In Assam, this took concrete form through the National Register of Citizens. The final NRC, published in August 2019 and using the 1971 cut-off from the Assam Accord, excluded over 19 lakh people from a list of roughly 3.3 crore applicants, leaving them facing the prospect of statelessness.

The picture grew more complicated with the Citizenship Amendment Act of 2019, which offered a path to citizenship for non-Muslim migrants from Bangladesh, Pakistan, and Afghanistan. In Assam, a notable share of those excluded from the NRC were reportedly Bengali Hindus, and the interaction between the NRC and the CAA created a tangle that indigenous organisations, refugee communities, and the courts are still working through. The deeper irony is that decades of accepting refugees on humanitarian grounds eventually produced one of India’s most polarising debates over national identity.

What do you think? Should a country that has absorbed refugees for over seven decades finally adopt a formal refugee law, or does the absence of one give India useful flexibility? And how should the rights of displaced communities be weighed against the genuine anxieties of indigenous populations who fear becoming minorities in their own homeland?
