Socialism in India has a long tradition, emerging from the struggle against imperialism and represents a significant part of the country's historical political heritage.

The socialist movement began to develop in India with the Russian Revolution. However, in 1871 a group in Calcutta had contacted Karl Marx with the purpose of organising an Indian section of the First International. It did not materialise. The first article in an Indian publication (in English) that mentions the names of Marx & Engels printed in the Modern Review in March 1912. The short biographical article titled Karl Marx – a modern Rishi was written by the German-based Indian revolutionary Lala Har Dayal. The first biography of Karl Marx in an Indian language was written by R. Rama Krishna Pillai in 1914.

Marxism made a major impact in India media at the time of the Russian Revolution. Of particular interest to many Indian papers and magazines was the Bolshevik policy of right to self-determination of all nations. Bipin Chandra Pal and Bal Gangadhar Tilak were amongst the prominent Indians who expressed their admiration of Lenin and the new rulers in Russia. Abdul Sattar Khairi and Abdul Zabbar Khairi went to Moscow, immediately on hearing about the revolution. In Moscow, they met Lenin and conveyed their greetings to him. The Russian Revolution also had an impact on émigré Indian revolutionaries, such as the Ghadar Party in North America.

India (ⁱ/ˈɪndiə/), officially the Republic of India (Bhārat Gaṇarājya), is a country in South Asia. It is the seventh-largest country by geographical area, the second-most populous country with over 1.2 billion people, and the most populous democracy in the world. Bounded by the Indian Ocean on the south, the Arabian Sea on the south-west, and the Bay of Bengal on the south-east, it shares land borders with Pakistan to the west;China, Nepal, and Bhutan to the north-east; and Burma and Bangladesh to the east. In the Indian Ocean, India is in the vicinity of Sri Lanka and the Maldives; in addition, India's Andaman and Nicobar Islands share a maritime border with Thailand and Indonesia.

Home to the ancient Indus Valley Civilisation and a region of historic trade routes and vast empires, the Indian subcontinent was identified with its commercial and cultural wealth for much of its long history. Four of the world's major religions—Hinduism, Buddhism, Jainism, and Sikhism—originated here, whereas Zoroastrianism, Christianity, and Islam arrived in the 1st millennium CE and also helped shape the region's diverse culture. Gradually annexed by and brought under the administration of the British East India Company from the early 18th century and administered directly by the United Kingdom from the mid-19th century, India became an independent nation in 1947 after a struggle for independence that was marked by non-violent resistance led by Mahatma Gandhi.

Indira Priyadarshini Gandhi (Hindi: इंदिरा प्रियदर्शिनी गांधी Indirā Priyadarśinī Gāndhī  listen (help·info), née Nehru; 19 November 1917 – 31 October 1984) was an Indian politician who served as the third Prime Minister of India for three consecutive terms (1966–77) and a fourth term (1980–84). Gandhi was the second female head of government in the world after Sirimavo Bandaranaike of Sri Lanka, and she remains as the world's second longest serving female Prime Minister as of 2012. She was the first woman to become prime minister in India.

Gandhi was the only child of Jawaharlal Nehru, the first prime minister of independent India. She adhered to the quasi-socialist policies of industrial development that had been begun by her father. Gandhi established closer relations with the Soviet Union, depending on that nation for support in India’s long-standing conflict with Pakistan. She was also the only Indian Prime Minister to have declared a state of emergency in order to 'rule by decree' and the only Indian Prime Minister to have been imprisoned after holding that office. She was assassinated by her Sikh bodyguards in retaliation for ordering Operation Blue Star.

The Constitution of India (Hindi: भारतीय संविधान; see also names in the other official languages) is the supreme law of India. It lays down the framework defining fundamental political principles, establishes the structure, procedures, powers, and duties of government institutions, and sets out fundamental rights, directive principles, and the duties of citizens. It is the longest written constitution of any sovereign country in the world, containing 444 articles in 24 parts, 12 schedules and 97 amendments. Besides the English version, there is an official Hindi translation. Bodhisattva Dr. Babasaheb Ambedkar[bhimrao ramji Ambedkar] is Chief Architect of Indian Constitution.

The Constitution was enacted by the Constituent Assembly on 26 November 1949, and came into effect on 26 January 1950. The date 26 January was chosen to commemorate the Purna Swaraj declaration of independence of 1930. With its adoption, the Union of India officially became the modern and contemporary Republic of India and it replaced the Government of India Act 1935 as the country's fundamental governing document. The Constitution declares India to be a sovereign, socialist, secular, democratic republic, assuring its citizens of justice, equality, and liberty, and endeavours to promote fraternity among them. The words "socialist" and "secular" were added to the definition in 1976 by constitutional amendment. India celebrates the adoption of the constitution on 26 January each year as Republic Day.
