Chinsurah is the home to the new state-of-the-art 1000 KW DRM transmitter of Prasar Bharti which enables 'Akashvaani Maitree' to be broadcast across Bangladesh. This special Bangla service of All India Radio was launched in the wake of the Bangladesh Liberation Movement and played a key role during the war, broadcasting Indian news bulletins in Bangladesh. It continued till April 2010 but was discontinued thereafter due to decommissioning of the Super Power Transmitter at Chinsurah.

The 1970s (pronounced "nineteen-seventies"; commonly shortened to the "Seventies" or the "'70s") was the decade that began on January 1, 1970, and ended on December 31, 1979.

In the 21st century, historians have increasingly portrayed the 1970s as a "pivot of change" in world history, focusing especially on the economic upheavals that followed the end of the postwar economic boom. On a global scale, it was characterized by frequent coups, domestic conflicts and civil wars, and various political upheavals and armed conflicts which arose from or were related to decolonization, and the global struggle between NATO, the Warsaw Pact, and the Non-Aligned Movement. Many regions had periods of high-intensity conflict, notably Southeast Asia, the Middle East, Latin America, and Africa.

The republics in the Commonwealth of Nations are the sovereign states in the organisation with a republican form of government. As of June 2022, 36 out of the 56 member states were republics. While King Charles III is the titular Head of the Commonwealth, he is not the head of state of the republican members. The King is however, the reigning monarch in the Commonwealth realms. The Head of the Commonwealth role does not carry with it any power; instead, it is a symbol of the free association of Commonwealth members.

Except for the former Portuguese possession of Mozambique, the former Belgian trust territory of Rwanda and the former French possessions of Gabon and Togo, they are all former British (or partly British) colonies or self-governing colonies that have evolved into republics. Most of the Commonwealth's members achieved independence while keeping the British monarch as their own individual head of state (in a form of personal union) and later became republics within the Commonwealth by abolishing the monarchy. In some other instances, the countries became republics after achieving independence from other former British colonies (as, for example, Bangladesh did from Pakistan in 1971 as a result of the Bangladesh Liberation War).

The Proclamation of Bangladeshi Independence (Bengali: বাংলাদেশের স্বাধীনতার ঘোষণাপত্র), refers to the declaration of independence of East Pakistan as Bangladesh on 26 March 1971, at the onset of the Bangladesh Liberation War by Bangabandhu Sheikh Mujibur Rahman. On that day, Bangladesh Awami League leader M. A. Hannan, and the following day Major Ziaur Rahman, broadcast the message on radio on behalf of Sheikh Mujibur Rahman from the Swadhin Bangla Betar Kendra radio station in Kalurghat, Chattogram. On 10 April, the Provisional Government of Bangladesh issued a proclamation on the basis of the previous declaration and established an interim constitution for the independence movement.

Bangladeshi English is a nativized variety of the English language that has evolved since its introduction in Bangladesh primarily as a medium of administration, education, and commerce during British colonial rule in the eighteenth century.

After independence in 1971, amid nationalist efforts to decolonize institutions, Bengali was established as the sole state language. But English still retained a significant role in higher education, government documents, judicial proceedings, and mass media, alongside remaining a compulsory subject in primary and secondary education.

East Pakistan was the eastern province of Pakistan between 1956 and 1971, restructured and renamed from the province of East Bengal and covering the territory of the modern country of Bangladesh. Its land borders were with India and Burma, with a coastline on the Bay of Bengal. To distinguish this region from India's state West Bengal (which is also known as "Indian Bengal"), East Pakistan was known as "Pakistani Bengal". East Pakistanis were popularly known as "Pakistani Bengalis". In 1971, East Pakistan became the newly independent state Bangladesh, which means "country of Bengal" or "country of Bengalis" or "land of Bengalis" in the Bengali language. In standard meaning, "desh" refers to a country, but in Bangla local expressions, "desh" also means one's village or countryside, hometown, ancestral heritage, homeland, and they do not have to be a politically formed sovereign country.

East Pakistan was formed with West Pakistan at the reorganization of One Unit Scheme orchestrated by the 3rd prime minister of Pakistan, Mohammad Ali. The Constitution of Pakistan of 1956 replaced the Pakistani monarchy with an Islamic republic. Bengali politician H.S. Suhrawardy served as the Prime Minister of Pakistan between 1956 and 1957 and a Bengali bureaucrat Iskander Mirza became the first President of Pakistan. The 1958 Pakistani coup d'état brought general Ayub Khan to power. Khan replaced Mirza as president and launched a crackdown against pro-democracy leaders. Khan enacted the Constitution of Pakistan of 1962 which ended universal suffrage. By 1966, Sheikh Mujibur Rahman emerged as the preeminent opposition leader in Pakistan and launched the six-point movement for autonomy and democracy. The 1969 uprising in East Pakistan contributed to Ayub Khan's overthrow. Another general, Yahya Khan, usurped the presidency and enacted martial law. In 1970, Yahya Khan organised Pakistan's first federal general election. The Awami League emerged as the single largest party, followed by the Pakistan Peoples Party. The military junta stalled in accepting the results, leading to civil disobedience, the Bangladesh Liberation War, 1971 Bangladesh genocide and persecution of Biharis.

Bihari (listen) is a demonym given to the inhabitants of the Indian state of Bihar. Bihari people can be separated into three main Indo-Aryan ethnolinguistic groups: Bhojpuris, Maithils and Magahis. They are also further divided into a variety of hereditary caste groups.In Bihar today, the Bihari identity is seen as secondary to caste/clan, linguistic and religious identity but nonetheless is a subset of the larger Indian identity. Biharis can be found throughout India, and in the neighbouring countries of Nepal, Pakistan and Bangladesh. During the Partition of India in 1947, many Bihari Muslims migrated to East Bengal (renamed to East Pakistan; later became Bangladesh). Bihari people are also well represented in the Muhajir people of Pakistan (formerly West Pakistan) because of Partition.

The Bangladesh genocide was the ethnic cleansing of Bengalis residing in East Pakistan (now Bangladesh) during the Bangladesh Liberation War, perpetrated by the Pakistan Army and the Razakars militia. It began on 25 March 1971, as Operation Searchlight was launched by West Pakistan (now Pakistan) to militarily subdue the Bengali population of East Pakistan; the Bengalis comprised the demographic majority and had been calling for independence from the Pakistani state. Seeking to curtail the Bengali self-determination movement, erstwhile Pakistani president Yahya Khan approved a large-scale military deployment, and in the nine-month-long conflict that ensued, Pakistani soldiers and local pro-Pakistan militias killed between 300,000 and 3,000,000 Bengalis and raped between 200,000 and 400,000 Bengali women in a systematic campaign of mass murder and genocidal sexual violence.

West Pakistanis in particular were shown by the news that the operation was carried out because of the 'rebellion by the East Pakistanis' and many activities at the time were hidden from them, including rape and ethnic cleansing of East Pakistanis by the Pakistani military. Although the majority of the victims were Bengali Muslims, Hindus were especially targeted. In their investigation of the genocide, the Geneva-based International Commission of Jurists concluded that Pakistan's campaign also involved the attempt to exterminate or forcibly remove a significant portion of the country's Hindu populace. The West Pakistani government, which had implemented discriminatory legislation in East Pakistan, asserted that Hindus were behind the Mukti Bahini (Bengali resistance fighters) revolt and that resolving the local "Hindu problem" would end the conflict—Khan's government and the Pakistani elite thus regarded the crackdown as a strategic policy. Genocidal rhetoric accompanied the campaign: Pakistani men believed that the sacrifice of Hindus was needed to fix the national malaise. In the countryside, Pakistan Army moved through villages and specifically asked for places where Hindus lived before burning them down. Hindus were identified by checking circumcision or by demanding the recitation of Muslim prayers. This also resulted in the migration of around eight million East Pakistani refugees into India, 80–90% of whom were Hindus.

Kazi Nazrul Islam (24 May 1899 – 29 August 1976) was a Bengali poet short story writer, journalist, lyricist and musician. He was later honored with the title of national poet of Bangladesh. Nazrul produced a large body of poetry, music, messages, novels, and stories with themes, that included equality, justice, anti-imperialism, humanity, rebellion against oppression and religious devotion. Nazrul Islam's activism for political and social justice as well as writing a poem titled as "Bidrohī", meaning "the rebel" in Bengali, earned him the title of "Bidrohī Kôbi" (Rebel Poet). His compositions form the avant-garde music genre of Nazrul Gīti (Music of Nazrul).

Born in the British Raj period into a Bengali Muslim Kazi family from Churulia in Asansol,then in Burdwan district in Bengal Presidency (now in West Bengal, India), Nazrul Islam received religious education and as a young man worked as a muezzin at a local mosque. He learned about poetry, drama, and literature while working with the rural theatrical group Leṭor Dôl, Leṭo being a folk song genre of West Bengal usually performed by the people from Muslim community of the region. He joined the British Indian Army in 1917 and was posted in Karachi. Nazrul Islam established himself as a journalist in Calcutta after the war ended. He criticised the British Raj and called for revolution through his famous poetic works, such as "Bidrohī" ('The Rebel') and "Bhangar Gan" ('The Song of Destruction'), as well as in his publication Dhūmketu ('The Comet'). His nationalist activism in Indian independence movement led to his frequent imprisonment by the colonial British authorities. While in prison, Nazrul Islam wrote the "Rajbôndīr Jôbanbôndī" ('Deposition of a Political Prisoner'). His writings greatly inspired Bengalis of East Pakistan during the Bangladesh Liberation War.
