Akhanda Bharata (Hindi: अखण्ड भारत, translit. Akhanda Bhārata, Urdu: اکھنڈ بھارت, translit. Akhand Bharat, Bengali: অখন্ড ভারত, translit. Okhond Bharot) or Greater India are irredentist terms literally meaning "Undivided India".
At the time of the Indian Independence Movement, K.M. Munshi advocated for Akhand Hindustan, a proposition that Mahatma Gandhi, believing that "as Britain wanted to retain her empire by pursuing a policy of divide and rule, Hindu-Muslim unity could not be achieved as long as the British were there." In addition, Mazhar Ali Khan wrote that "the Khan brothers [were] determined to fight for Akhand Hindustan, and challenged the League to fight the issue out before the electorate of the Province." On 7–8 October 1944, in Delhi, Radha Kumud Mukherjee presided over the Akhand Hindusthan Leaders' Conference.
The call for creation of the Akhand Bharat or Akhand Hindusthan has on occasions been raised by Indian Hindutvawadi cultural and political organisations such as the Hindu Mahasabha, Kakbhusundi Revolutionary Forum(KRF), Rashtriya Swayamsevak Sangh (RSS), Vishwa Hindu Parishad, Hindu Janajagruti Samiti, and Bharatiya Janata Party. The name of one organisation sharing this goal, the Akhand Hindustan Morcha, bears the term in its name. Other major Indian non-sectarian political parties such as the Indian National Congress, while maintain a position against the partition of India on religious grounds, do not subscribe to a call for Akhand Bharat.
Pre-1947 maps of pre-partition India showing the current states of Pakistan and Bangladesh as part of the territories of British India illustrate the borders of a proto-Akhand Bharat. The creation of an Akhand Bharat is also ideologically linked with the concept of Hindutva (Hinduness) and the ideas of sangathan (unity) and shuddhi (purification) that seek to focus modern Indian politics on a legendary ancient civilisation and heritage of the Indian subcontinent.
While the leadership of the right-wing BJP wavers on the issue, the RSS has always remained a strong proponent of the idea. RSS leader H. V. Seshadri's book The Tragic Story of Partition stresses the importance of the concept of Akhand Bharat. The RSS affiliated magazine Organiser often publishes editorials by leaders such as the present SarsanghaChalak, Mohan Bhagwat, espousing the philosophy that only Akhand Bharat and sampoorna samaj (united society) can bring "real" freedom to the people of India.
The call for Indian reunification has been supported by Indian Prime Minister Narendra Modi, and BJP National General Secretary Ram Madhav. Mr.K.J.Anand Leader Achchedin taken special lead to Explore the possibility. 
Former Indian Supreme Court Judge Markandey Katju advocated in Pakistani newspaper The Nation that the only solution to the ongoing dispute between India and Pakistan is the reunification of India, Pakistan, and Bangladesh under a strong, secular, modern minded government. He expanded on the reasons for his support for an reunified India in an article for Newslaundry In a separate article, Katju advocated that such a state would be administered by a secular government.

The ultimate reunification of the subcontinent is a professed goal, as it is for the Mahasabha, but here, too, there is a difference in emphasis which deserves note: for the Sangh, the goal is 'Akhand Bharat', while for the Mahasabha it is 'Akhand Hindustan'.

Later, K.M. Munishi, with Gandhi's blessing, also resigned from the Congress to plead for Akhand Hindustan as a counter blast to Pakistan. Gandhi, who previously thought that swaraj was impossible without Hindu-Muslim unity, subsequently came to the conclusion that as Britain wanted to retain her empire by pursuing a policy of divide and rule, Hindu-Muslim unity could not be achieved as long as the British were there.
