Let’s go back to one of the most significant chapters in India’s political history, the formation of the All India Forward Bloc (AIFB). One of the country’s oldest left-wing nationalist parties, the AIFB was born out of the revolutionary vision of Subhas Chandra Bose. It was founded in 1939 after breaking away from the Indian National Congress and has had a long, eventful journey through the freedom struggle and post-independence politics.
Once a strong presence in states like Tamil Nadu, Andhra Pradesh, Kerala, and Assam, the AIFB today is mostly confined to West Bengal, with no current representatives in Parliament or any state assembly. G. Devarajan currently serves as its Secretary-General, but the party’s national influence has faded over time.
Building the Foundation of the All India Forward Bloc
The AIFB’s story begins with growing ideological rifts within the Indian National Congress. On 29 April 1939, Subhas Chandra Bose resigned as Congress President after clashing with Mahatma Gandhi. While Gandhi favoured a more moderate approach, Bose was determined to push for complete independence through more radical means.
Just a few days later, on 3 May 1939, Bose announced the formation of the Forward Bloc in Makur, Unnao, Uttar Pradesh. His goal was to unite the left-leaning elements within the Congress under one revolutionary platform.
In Calcutta, Bose made a dramatic appeal to his supporters, urging them to dedicate their lives to resisting British rule. Seventeen young women symbolised this commitment by signing their pledge in blood, a powerful display of devotion. Bose took charge as party president, with S.S. Kavishar as vice-president. Influential leaders from across India joined him, including Vishwambhar Dayalu Tripathi, Khurshed Nariman, Hari Vishnu Kamath, and U. Muthuramalingam Thevar.
By June 1939, the party held its first conference in Bombay, where it drafted a constitution and laid out its ideological roadmap. In August, Bose launched a newspaper called Forward Bloc to spread the party’s message. He travelled extensively to mobilise public support, positioning the AIFB as a radical alternative to the Congress.
The Story of the All India Forward Bloc
Turning socialist
In June 1940, during the first All India Conference in Nagpur, the Forward Bloc adopted socialism as its guiding principle. The party also introduced the slogan ‘All Power to the Indian People’, and 22 June was declared its official founding day. The conference passed a resolution in favour of launching an active struggle against British rule. Bose remained party president, while H.V. Kamath became general secretary.
Bose’s arrest and daring escape
The movement faced a serious blow when Bose was arrested on 2 July 1940 and imprisoned in Calcutta’s Presidency Jail. But true to his spirit, he escaped from house arrest in January 1941. He travelled through Afghanistan, hoping to gain Soviet support. When that failed, he went to Germany, where he established the Free India Centre in Berlin and formed the Indian Legion to fight alongside Axis forces against British rule.
Back in India, Forward Bloc activists continued to push for independence. While many weren’t directly connected to the INA or Bose’s operations abroad, underground groups like Azad Dasta distributed leaflets and spread revolutionary messages inspired by Bose’s ideas.
Rebuilding after the war
As World War II ended, the AIFB tried to regroup. In February 1946, R.S. Ruiker organised a national meeting in Jabalpur, which led to the formation of the FB Workers Assembly, a legal front for the then-banned party. The gathering reaffirmed its commitment to socialism, class struggle, and grassroots activism.
By June 1946, the British government lifted the ban on the party. This gave the AIFB a chance to re-enter formal politics. H.V. Kamath was elected to the Constituent Assembly, while Lila Roy and Hemantha Kumar Basu secured seats in Bengal. It marked a return to political relevance.
Early splits and internal conflicts
But unity didn’t last. At the second national conference in January 1947, held in Arrah, Bihar, S.S. Kavishar became party president and Marxist leader Sheel Bhadra Yagee was elected general secretary. This marked the beginning of ideological and organisational tensions within the party.
After India’s independence, these internal conflicts only deepened. In February 1948, Congress expelled all internal dissidents, prompting the AIFB to cut ties completely. Then came a divisive decision, to split the party into separate units for India and Pakistan. This move led to anger, especially among Bengal leaders. The Bengal committee was dissolved, and separate East and West Bengal units were created. By the end of 1948, the AIFB had split into two main factions: one led by Ruiker and Kavishar in Chandannagar, and another led by Yagee in Calcutta.
Struggles and Setbacks
In the early 1950s, the party’s electoral fortunes began to decline. It contested the 1951 electoral college elections in Tripura but failed to win any seats. At its fifth national conference in Puri in 1952, Mohan Singh was elected chairman and Dhillon became general secretary.
In 1955, Yagee and Singh unilaterally announced a merger with the Congress Party, arguing that Congress had embraced socialist policies. This move angered the AIFB’s core leadership. The Central Committee, meeting in Nagpur, expelled both leaders and appointed Hemanta Kumar Bose and R.K. Haldulkar to replace them.
New alliances and further breakaways
In 1964, the Forward Bloc briefly aligned with the Samyukta Socialist Party, taking part in joint campaigns in Delhi. However, it stopped short of a full merger. In Tamil Nadu, the death of U. Muthuramalingam Thevar in 1963 led to a power struggle. P.K. Mookiah Thevar emerged as the leader, but his rival Sasivarna Thevar broke away to form the Subhasist Forward Bloc.
In Tripura, the party joined the Progressive Front in 1965, along with CPI and other left-leaning parties. They campaigned for land reforms, nationalisation of foreign capital, and a stronger national defence. But the alliance collapsed before the 1967 elections, and the AIFB didn’t contest.
Regional turmoil and ideological conflicts
In 1968, further fragmentation occurred in Tamil Nadu. Leaders Velayudham Nayar and S. Andi Thevar accused the party of abandoning its socialist roots by working with the right-wing Swatantra Party. They left and formed the Revolutionary Forward Bloc.
That same year in West Bengal’s West Dinajpur district, violent clashes erupted between peasants aligned with CPI(M) and refugee cultivators backed by the Forward Bloc. CPI(M) leader Hare Krishna Konar criticised the violence, seeing it as a failure of agrarian unity.
Adapting to a changing political landscape
In 1969, the Congress Party split, with Indira Gandhi breaking away from the old guard. This reshaped Indian politics and left smaller parties like the AIFB struggling for space. Over time, the party’s influence shrank to a few pockets, particularly in West Bengal.
Legacy and Present-Day Status
The All India Forward Bloc’s journey reflects the challenges of maintaining a revolutionary legacy in changing times. Founded on Subhas Chandra Bose’s bold vision of militant socialism, the party was once a strong force in India’s freedom movement and early post-independence years. But internal splits, shifting alliances, and electoral setbacks weakened its national presence.
Today, under G. Devarajan’s leadership, the AIFB is a marginal player with limited regional influence. Despite this, the party’s history, shaped by Bose’s defiance, his dramatic escape, and his unwavering commitment to justice, remains a source of inspiration. Even as its political strength has faded, the Forward Bloc continues to symbolise the enduring power of radical ideas in Indian politics.
