After India's independence from the
British Empire in August 1947, Portugal continued to hold a handful of
exclaves on the Indian subcontinent—the districts of
Goa,
Daman and Diu and
Dadra and Nagar Haveli—collectively known as the
State of India. Goa, Daman and Diu covered an area of around and held a population of 637,591. The Goan
diaspora was estimated at 175,000 (about 100,000 within the Indian Union, mainly in Bombay). Religious distribution was 61% Hindu, 37% Christian (mostly Catholic) and 2% Muslim.
Local resistance to Portuguese rule Resistance to Portuguese rule in Goa in the 20th century was pioneered by
Tristão de Bragança Cunha, a French-educated Goan engineer who founded the Goa Congress Committee in Portuguese India in 1928. Cunha released a booklet called 'Four hundred years of Foreign Rule', and a pamphlet, 'Denationalisation of Goa', intended to sensitise Goans to the oppression of Portuguese rule. Messages of solidarity were received by the Goa Congress Committee from leading figures in the Indian independence movement including
Rajendra Prasad,
Jawaharlal Nehru and
Subhas Chandra Bose. On 12 October 1938, Cunha with other members of the Goa Congress Committee met Subhas Chandra Bose, the President of the
Indian National Congress, and on his advice, opened a Branch Office of the Goa Congress Committee at 21, Dalal Street,
Bombay. The Goa Congress was also made affiliate to the Indian National Congress and Cunha was selected as its first President. In June 1946,
Ram Manohar Lohia, an Indian Socialist leader, entered Goa on a visit to his friend,
Juliao Menezes, a nationalist leader, who had founded the Gomantak Praja Mandal in Bombay and edited the weekly newspaper
Gomantak. Cunha and other leaders were also with him. On 18 June 1946, now celebrated as
Goa Revolution Day, the Portuguese government disrupted a protest against the suspension of civil liberties in
Panaji (then spelt 'Panjim') organised by Lohia, Cunha and others including
Purushottam Kakodkar and
Laxmikant Bhembre in defiance of a ban on public gatherings, and arrested them. There were intermittent mass demonstrations from June to November. In addition to non-violent protests, armed groups such as the
Azad Gomantak Dal (Free Goa Party) and the
United Front of Goans (UFG) conducted violent attacks aimed at weakening Portuguese rule in Goa. The
Indian government supported the establishment of armed groups like the Azad Gomantak Dal, giving them full financial, logistic and armament support. The armed groups acted from bases situated in Indian territory and under cover of Indian police forces. The Indian government—through these armed groups—attempted to destroy economic targets, telegraph and telephone lines, road, water and rail transport, in order to impede economic activity and create conditions for a general uprising of the population. A Portuguese army officer stationed with the army in Goa, Captain Carlos Azaredo, stated in 2001 in the Portuguese newspaper
Expresso: "To the contrary to what is being said, the most evolved guerrilla warfare which our Armed Forces encountered was in Goa. I know what I'm talking about, because I also fought in Angola and in Guinea (
Portuguese Guinea). In 1961 alone, until December, around 80 policemen died. The major part of the freedom fighters of Azad Gomantak Dal (AGD) were not Goans. Many had fought in the
British Army, under
General Montgomery, against the
Germans."
Diplomatic efforts to resolve Goa dispute On 27 February 1950, the government of India asked the Portuguese government to open negotiations about the future of Portuguese colonies in India. Portugal asserted that its territory on the Indian subcontinent was not a colony but part of metropolitan Portugal and hence its transfer was non-negotiable, and that India had no rights to this territory because the Republic of India did not exist at the time when Goa came under Portuguese rule. When the Portuguese government refused to respond to subsequent aide-mémoires in this regard, the Indian government, on 11 June 1953, withdrew its diplomatic mission from Lisbon. By 1954, the Republic of India instituted visa restrictions on travel from Goa to India which paralysed transport between Goa and other exclaves like Daman, Diu, Dadra and Nagar Haveli. Meanwhile, the Indian Union of Dockers had, in 1954, instituted a boycott on shipping to Portuguese India. Between 22 July and 2 August 1954, armed activists attacked and forced the surrender of Portuguese forces stationed in Dadra and Nagar Haveli. On 15 August 1955, 3,000–5,000 unarmed Indian activists attempted to enter Goa at six locations and were violently repulsed by Portuguese police officers, resulting in the deaths of between 21 and 30 people. The news of the incident built public opinion in India against the presence of the Portuguese in Goa. On 1 September 1955, India shut its consul office in Goa. In 1956, the Portuguese ambassador to France, Marcello Mathias, along with Portuguese Prime Minister
António de Oliveira Salazar, argued in favour of a referendum in Goa to determine its future. This proposal was however rejected by the Ministers for Defence and Foreign Affairs. The demand for a referendum was repeated by presidential candidate General
Humberto Delgado in 1957.
Mexico offered the Indian government its influence in Latin America to bring pressure on the Portuguese to relieve tensions. Meanwhile,
Krishna Menon, India's defence minister and head of India's UN delegation, stated in no uncertain terms that India had not "abjured the use of force" in Goa. On 24 November 1961,
Sabarmati, a passenger boat passing between the Indian port of
Kochi and the Portuguese-held island of
Anjidiv, was fired upon by Portuguese ground troops, resulting in the death of a passenger and injuries to the
chief engineer. The action was precipitated by Portuguese fears that the boat carried a military
landing party intent on storming the island. The incidents lent themselves to fostering widespread public support in India for military action in Goa. Eventually, on 10 December, nine days prior to the armed action, code named Operation Vijay, Nehru stated to the press: "Continuance of Goa under Portuguese rule is an impossibility".
Annexation of Dadra and Nagar Haveli The hostilities between India and Portugal started seven years before the annexation of Goa, when
Dadra and Nagar Haveli were invaded and occupied by pro-Indian forces with the support of the Indian authorities.
Dadra and
Nagar Haveli were two Portuguese landlocked exclaves of the
Daman district, totally surrounded by Indian territory. The connection between the exclaves and the coastal territory of Daman had to be made by crossing about of Indian territory. Dadra and Nagar Haveli did not have any Portuguese military garrison, but only police forces. The Indian government started to develop isolation actions against Dadra and Nagar Haveli already in 1952, including the creation of impediments to the transit of persons and goods between the two landlocked enclaves and Daman; the use of these
economic warfare tactics by India caused a deep economic depression in Goa with subsequent hardship for the inhabitants and, in attempt to remedy the situation and with land travel precluded, Salazar established a new airline to communicate the enclaves of
Portuguese India with its ports. In July 1954, pro-Indian forces, including members of organisations like the United Front of Goans, the National Movement Liberation Organisation, the
Communist Party of India, the
Rashtriya Swayamsevak Sangh and the
Azad Gomantak Dal, with the support of Indian Police forces, began to launch assaults against Dadra and Nagar Haveli. On the night of 22 July, UFG forces stormed the small Dadra police station, killing Police Sergeant Aniceto do Rosário and Constable António Fernandes, who resisted the attack. On 28 July, RSS forces took Naroli police station. Surrounded and prevented from receiving reinforcements by the Indian authorities, the Portuguese Administrator and police forces in Nagar Haveli eventually surrendered to the Indian police forces on 11 August 1954. Portugal appealed to the
International Court of Justice, which, in a decision dated 12 April 1960, stated that Portugal had sovereign rights over the territories of Dadra and Nagar Haveli but India had the right to deny passage to armed personnel of Portugal over Indian territories. Therefore, the Portuguese authorities could not legally pass through Indian territory. ==Events preceding the hostilities==
