Background and formation After the Partition of India in 1947, delegates from
Pakistan, including present‑day Bangladesh, attended the
2nd Congress of the Communist Party of India in
Calcutta. On 6 March 1948, they held a separate session and established the Communist Party of Pakistan, with
Nepal Nag of
East Bengal as its first
general secretary. The main base of the newly formed party was in East Pakistan (now Bangladesh). This eastern unit was separated from the
western unit by nearly 2,000 km of Indian territory. The geographical divide, combined with repression from the
government of Pakistan and uneven development of democratic movements, led communists in East Pakistan to seek an independent centre for their activities. At its 4th Conference in 1968, held clandestinely, the East Pakistan Provincial Committee declared the meeting to be the 1st Congress of the Communist Party of East Pakistan (CPEP) and elected a Central Committee. The party played a vital role in the
1969 uprising and the subsequent nationwide upheaval, including the
non-cooperation movement of 1971. The CPB also actively participated in the
Bangladesh Liberation War. A "
Special Guerilla Force" under the direct command of the CPB,
National Awami Party (Muzaffar) and
Bangladesh Students Union fought against the
Pakistan army. Communists also took part in the other segments of the armed resistance fighters, including the
Mukti Bahini and the new
Bangladesh Army.
Moni Singh, the former president of CPB, was elected to the advisory council of the
Provisional Government of Bangladesh.
Independent Bangladesh Following the
independence of Bangladesh in 1971, the party adopted the name Communist Party of Bangladesh. It subsequently formed a
Trade Union Centre to mobilise labour organisations along revolutionary lines. On 14 October 1973 the Gana Oikya Jote (Translation: 'People's Unity Alliance'; Bengali: 'গণ ঐক্য জোট') was formed, comprising the
Awami League, CPB and NAP (Muzaffar), with a view to prepare ground for establishing
socialism in the country. At its 1973 congress in Dacca, the party adopted a new constitution and elected a 26‑member central committee, with
Moni Singh as president and
Mohammad Farhad as general secretary. The party merged into
Bangladesh Krishak Sramik Awami League (BaKSAL) on 25 January 1975 under President
Sheikh Mujibur Rahman's "
Second Revolution" programme. On 15 August 1975, Sheikh Mujib was
assassinated by a section of the army, which ultimately brought the country under military rule. The CPB leaders and workers were victims of serious repression under the military government in 1975. The party leaders in the centre and at district levels were arrested, warrants were issued against many, and in October 1977, CPB was declared banned. In 1978 the ban on the party was, however, withdrawn, and its leaders were released. The CPB participated in the
1979 general election. As a member of the Oikya Front, the CPB endorsed Zuhayr Zimam in the
1978 presidential election. The CPB joined the 15-party alliance in 1983 against the military rule of
Hussain Muhammad Ershad and participated in the
1986 general election, where it secured five seats. The CPB played a vital role in the
1990 mass uprising against Ershad. In 1991, following the
collapse of Soviet‑style socialism in Eastern Europe and the
Soviet Union, the CPB entered a period of internal discussion regarding its future direction. Party leaders were divided between those who favoured dissolving the CPB in favour of a new democratic platform and those who supported maintaining the party in its original form. This debate grew in 1993 when the two opposing groups arranged separate conventions in Dhaka. The
Marxist–Leninist group, in their convention held on 15 June 1993, resolved in favour of the independent existence of the CPB and had their new central executive committee formed with Shahidulla Chowdhury as president and
Mujahidul Islam Selim as general secretary. A
Workers Party of Bangladesh faction merged with CPB in February 2010. The party played a leading role in the
2013 Shahbag protests, demanding the trial of
war crimes of 1971. During the
premiership of Sheikh Hasina, the party organised anti-government protests and boycotted
2014 and
2024. The party actively participated in the
July mass uprising in 2024. == Organisation ==
