Tamil Nadu's Biggest Political 'What If': When DMK And AIADMK Almost Merged

Last Updated:May 09, 2026, 10:10 IST

As speculation grows over a possible DMK-AIADMK understanding against Vijay’s TVK, a look back at the little-known 1979 attempt to merge Tamil Nadu’s two Dravidian giants.

Speculation surrounding a possible political understanding between All India Anna Dravida Munnetra Kazhagam (AIADMK) and Dravida Munnetra Kazhagam (DMK) has revived one of the most dramatic “what if" moments in Tamil Nadu’s political history, a time when the two Dravidian rivals almost merged under the mediation of Biju Patnaik.

The fresh round of merger rumours comes amid uncertainty over government formation in Tamil Nadu after the Assembly election results. Sources told CNN-News18 that the AIADMK is exploring the possibility of leaving the BJP-led NDA if actor-politician Vijay’s TVK fails to cross the majority mark of 118 seats.

Sources further said the DMK has conveyed that any possibility of outside support to an AIADMK-led arrangement would require the AIADMK to sever ties with the BJP first.

While the current discussions remain speculative, they have triggered renewed interest in a forgotten political episode from 1979, when a formal merger between the DMK and AIADMK came surprisingly close to becoming reality.

When Biju Patnaik Tried To Unite DMK And AIADMK

The merger attempt took place during one of the most unstable phases in national politics.

It was September 1979, barely two years after the Emergency. Morarji Desai had resigned following defections within the Janata Party coalition, while Charan Singh had become caretaker Prime Minister after Congress (I), led by Indira Gandhi, withdrew support to his government within weeks.

In Tamil Nadu, MG Ramachandran, popularly known as MGR, was serving his first term as chief minister. His party, the AIADMK, was supporting the Charan Singh government at the Centre.

At the time, MGR was also exploring political possibilities with Indira Gandhi ahead of the looming general elections. But after a scheduled meeting between Indira Gandhi and MGR reportedly failed to materialise on September 6, Biju Patnaik, late father of former Odisha CM Naveen Patnaik, stepped in with a far more ambitious political idea.

Biju Patnaik, then a senior Janata Party leader and former Union Steel Minister, shared a close rapport with former DMK chief M. Karunanidhi. He believed a reunited Dravidian movement could prevent Congress from regaining dominance nationally.

On September 12, 1979, Patnaik met Karunanidhi at his residence in Madras and floated the idea of a merger between the DMK and AIADMK. When Karunanidhi asked whose proposal it was, Patnaik reportedly told him that MGR himself wanted the merger and wished to know the DMK leader’s conditions.

What Were Karunanidhi’s Conditions?

The conditions proposed by Karunanidhi reflected how serious the negotiations had become.

Karunanidhi reportedly agreed that MGR could continue as chief minister if the merger went through. He also agreed to retain the AIADMK’s flag, carrying the image of CN Annadurai.

However, Karunanidhi wanted the merged party to retain the DMK name because of its historical association with Annadurai, popularly known as Anna, who founded the DMK and became one of the central figures of the Dravidian movement. He also proposed that he himself would serve as president of the merged party.

The response reportedly surprised Patnaik. According to The News Minute, Patnaik hugged Karunanidhi after hearing the terms and remarked that he had expected “impossible terms".

The negotiations then moved quickly.

Patnaik arranged a meeting between Karunanidhi and MGR at the Chepauk Guest House in Madras the following day. While senior leaders including DMK general secretary K Anbazhagan and AIADMK leaders VR Nedunchezhian and Panruti Ramachandran were present in the building, MGR and Karunanidhi held a one-on-one discussion in a separate room.

The broad contours of the merger were reportedly agreed upon. Both parties were expected to convene emergency executive council meetings to formally pass resolutions approving the merger.

For a brief moment, Tamil Nadu’s Dravidian rivalry appeared close to ending.

Why The Merger Suddenly Collapsed

The proposed merger collapsed almost as suddenly as it emerged.

The day after the Chepauk meeting, MGR addressed a public gathering in Vellore. Instead of announcing the merger, ministers from the AIADMK attacked the DMK openly. The proposal was effectively dead.

Over the years, several explanations emerged regarding what changed MGR’s mind.

More than three decades later, Karunanidhi publicly suggested that AIADMK minister Panruti Ramachandran had played a key role in discouraging MGR from proceeding.

Recalling the episode at an awards function in Chennai, Karunanidhi said his meeting with MGR had been cordial. “He left for Vellore after the meeting. I do not know what happened in the car," Karunanidhi said, while hinting that an “undesirable" person accompanying MGR may have influenced the final decision.

But beyond individual personalities, political observers have long argued that the merger failed because both parties ultimately recognised the importance of remaining rivals.

Although the AIADMK had emerged from a split within the DMK, the rivalry between the two parties had by then become central to Tamil Nadu’s political identity. The DMK needed the AIADMK as its principal challenger, while the AIADMK relied on opposition to the DMK to preserve its own political identity and emotional connection with cadres.

How The Failed Merger Shaped Tamil Nadu Politics

The collapse of the 1979 merger attempt ended up shaping Tamil Nadu politics for decades.

For nearly half a century afterwards, the DMK and AIADMK dominated the state through a stable bipolar structure. Despite fierce political battles, both parties operated within the broader ideological framework of the Dravidian movement.

That political equilibrium is now facing a new challenge with the rise of Vijay and his party, TVK.

Unlike earlier phases of Tamil Nadu politics, Vijay is entering a political landscape shaped by social media-driven narratives, weaker ideological loyalties among younger voters and growing anti-establishment sentiment.

This has intensified speculation over whether traditional rivals could consider tactical cooperation to prevent a major political realignment.

Why The 1979 Episode Is Being Discussed Again

The renewed discussions around a possible DMK-AIADMK understanding are not merely about arithmetic. They have reopened larger questions about the future of Tamil Nadu’s political order.

In 1979, the merger attempt failed despite both leaderships reportedly agreeing on power-sharing terms. The fear then was that organisational unity could weaken political identity.

Today, the anxiety appears different.

The rise of Vijay has triggered concerns within established political circles about the possibility of a generational shift outside the traditional DMK-AIADMK axis. That is why even speculative conversations about tactical cooperation between long-time rivals have generated enormous attention.

Whether the current rumours materialise politically remains uncertain. But the very discussion has brought back memories of the moment when Biju Patnaik nearly achieved what still remains one of the most extraordinary unrealised political realignments in Tamil Nadu’s history.
