India-Portugal Relations Explained

India-Portugal relations are the diplomatic, economic, cultural and people-to-people ties between the Republic of India and the Portuguese Republic, shaped by nearly five centuries of Portuguese presence on India’s western coast and reset on a cooperative footing after diplomatic relations were restored in 1974. The relationship is unusual because the same history that once divided the two countries, the Portuguese colonial chapter centred on Goa, now supplies much of the warmth in the partnership through shared heritage, a large diaspora and a common interest in the European Union (EU) market.

Today India-Portugal relations rest on a treaty settlement signed in 1974, high-level visits in the 2000s and 2010s, a migration and mobility pact concluded in 2017, and growing links in trade, information technology, pharmaceuticals, maritime affairs and education. This explainer sets out how the relationship developed, what it covers today and why Portugal matters to India as a partner inside Europe.

Key Takeaways

• India-Portugal relations were severed in 1955 over Goa and restored in 1974, when Portugal’s Carnation Revolution ended the Estado Novo dictatorship.
• Portugal formally recognised Indian sovereignty over Goa, Daman, Diu, and Dadra and Nagar Haveli through a treaty signed in New Delhi in December 1974.
• Persons born in Portuguese India before 1961, and their descendants, can seek Portuguese nationality, which has given many Goans a Portuguese and therefore EU passport.
• The first India-EU summit was held in Lisbon in 2000, and Portugal hosted the India-EU leaders’ meeting in Porto in 2021 during its EU presidency.
• Portugal is a gateway for Indian firms to the EU single market, the Atlantic coast and Portuguese-speaking markets such as Brazil, Angola and Mozambique.
• Cultural overlap is deep: Portuguese loanwords, Goan cuisine, the Goa Civil Code and the churches of Old Goa all trace to the shared past.

What is the history behind India-Portugal relations?

The history behind India-Portugal relations begins in 1498, when the navigator Vasco da Gama reached Calicut (now Kozhikode) on the Malabar coast after sailing around Africa. This voyage opened the direct sea route between Europe and India and made Portugal the first European power to build a lasting maritime empire in the Indian Ocean.

In 1510 the Portuguese governor Afonso de Albuquerque captured Goa from the Bijapur Sultanate, and Goa became the capital of the Estado da India, the Portuguese state in Asia. Over time the Portuguese held trading posts and territories at several places along the Indian coast, including Cochin, Daman, Diu and the inland enclaves of Dadra and Nagar Haveli. Most of these were lost to Dutch, British and Maratha power over the following centuries, but Goa, Daman and Diu remained under Portugal.

The Portuguese presence left a mixed legacy. It introduced new crops, architecture, printing and a Catholic community, and it also brought religious conflict, notably the Goa Inquisition, and the loss of political self-rule. Historians continue to debate its balance, and a neutral reading acknowledges both the cultural exchange and the coercion involved.

How did Goa become part of India?

Goa became part of India in December 1961, when Indian armed forces entered the Portuguese territories of Goa, Daman and Diu in an operation known as Operation Vijay, after years of failed diplomacy. When the British left in 1947, India expected the remaining European enclaves, French and Portuguese, to be transferred. France negotiated a gradual handover of its territories, but Portugal, then governed by the authoritarian Estado Novo regime under Antonio de Oliveira Salazar, treated its Indian possessions as overseas provinces of Portugal and refused to negotiate.

The dispute escalated in stages:

• In 1954, local activists and volunteers took control of Dadra and Nagar Haveli, which Portugal could not easily reach by land.
• In 1955, Indian satyagrahis attempted to enter Goa peacefully and were met with force, after which India closed its legation in Lisbon and diplomatic relations ended.
• In 1960, the International Court of Justice (ICJ) gave judgment in the Right of Passage over Indian Territory case brought by Portugal, a ruling that largely supported India’s position on the passage of armed forces.
• In December 1961, the Indian armed forces moved into Goa, Daman and Diu, and the Portuguese Governor-General, Manuel Vassalo e Silva, surrendered after a short operation.

Portugal did not recognise the change for more than a decade, and the matter caused a long diplomatic freeze. India regards the event as the completion of decolonisation, while Portugal at the time protested it, and Portuguese public opinion has since become more reflective. Goa became a full state of the Indian Union in 1987, while Daman and Diu were later merged with Dadra and Nagar Haveli into a single Union Territory in 2020.

How were diplomatic relations restored in 1974?

Diplomatic relations between India and Portugal were restored in 1974 after the Carnation Revolution of 25 April 1974 overthrew the Estado Novo and brought democracy to Portugal. The new Portuguese government quickly moved to end the colonial wars in Africa and to settle the Indian question.

In December 1974, the two governments signed a treaty in New Delhi in which Portugal recognised Indian sovereignty over Goa, Daman, Diu, and Dadra and Nagar Haveli, and both sides agreed to restore diplomatic relations. Portuguese Foreign Minister Mario Soares, later Prime Minister and President of Portugal, was one of the key figures on the Portuguese side. The treaty also addressed practical matters such as the status of people affected by the transfer.

The settlement allowed both countries to reopen embassies and begin building a relationship free of the territorial dispute. Soares took a continuing personal interest in India, and his successors continued the effort to place ties on a modern footing.

What does the India-Portugal relationship cover today?

The India-Portugal relationship today covers political dialogue, trade and investment, migration and mobility, education, culture, science, maritime cooperation and multilateral coordination. The two governments hold regular foreign-office consultations and maintain agreements on matters such as the avoidance of double taxation, cultural exchange and technical cooperation.

The relationship gained momentum in the 2010s. Antonio Costa, then Prime Minister of Portugal and a politician of Goan descent, visited India in January 2017 and was the chief guest at the Pravasi Bharatiya Divas convention in Bengaluru. Prime Minister Narendra Modi visited Lisbon later in 2017, and the visits produced a package of agreements, including the migration and mobility pact discussed below. The two leaders met again at the India-EU leaders’ meeting in Porto in May 2021, held during the Portuguese presidency of the Council of the EU.

Portugal also takes part in EU-level discussions about India, including trade and investment negotiations, connectivity and technology partnerships. Because Portugal is a member of the EU, much of its India policy is coordinated with Brussels, but the bilateral track remains important for specific agreements.

Key areas of cooperation

• Political and diplomatic consultations, including foreign-office dialogue and parliamentary exchanges.
• Trade, investment, tourism and start-up links.
• Migration, mobility, student and professional exchanges.
• Culture, language teaching and heritage conservation, especially in Goa.
• Science and technology, space, renewable energy and pharmaceuticals.
• Maritime affairs, ports and shipping.

What is the India-Portugal migration and mobility pact?

The India-Portugal migration and mobility pact is a 2017 arrangement between the two governments designed to make legal movement of students, professionals and workers between the two countries easier and to discourage irregular migration. The pact was signed during the high-level visits of 2017 and reflected a shared view that people-to-people links are a main strength of the relationship.

The pact matters for several reasons. It gives a legal framework for skilled workers, researchers and students; it supports cooperation against human trafficking and illegal migration; and it provides a channel for dealing with consular matters affecting Indian nationals in Portugal. Portugal has an ageing population and labour shortages in sectors such as agriculture, tourism, construction and information technology, while India has a large pool of skilled and semi-skilled workers.

The pact operates alongside Portugal’s own immigration rules and EU law. Indian nationals in Portugal include professionals in technology and finance, students in Portuguese universities and workers in agriculture, notably in southern Portugal. Both governments have stated that safe, orderly and regular migration is a mutual interest, and implementation continues to evolve with changes in Portuguese visa and residence policy.

Why do so many Goans hold Portuguese passports?

Many Goans hold Portuguese passports because Portuguese nationality law allows people born in Portuguese India before 1961, and their descendants, to register as Portuguese citizens. Under the rules developed after 1974 and consolidated in the Portuguese Nationality Act, persons who were Portuguese subjects before the transfer of territory could keep a route to citizenship, provided they met documentary requirements such as a birth record from the Goa civil registry and registration in Portugal.

A Portuguese passport is also an EU passport, which gives the holder the right to live and work across the EU and, before Brexit, the United Kingdom. This explains why large Goan communities exist in Portugal, the United Kingdom and other European countries. Many Goans entered the UK in the 1990s and 2000s using Portuguese citizenship, and the Goan diaspora is a significant link between India, Portugal and Britain.

Indian law does not permit dual citizenship, so Goans who acquire a Portuguese passport generally give up Indian citizenship but may apply for Overseas Citizen of India (OCI) status, which gives long-term residence and work rights in India without full citizenship. Portugal has revised the eligibility and procedure for nationality claims at various points, so applicants need to check the current rules. The question has attracted debate in both countries, and it remains one of the most visible features of the relationship.

Who are the Indian-origin communities in Portugal?

The Indian-origin communities in Portugal include Goan Catholics and Hindus, Gujarati families who arrived from Mozambique, Daman and Diu, and newer migrants from Punjab, Nepal and other parts of South Asia. They form a small but visible part of Portuguese society and have become part of its political and business life.

Several groups can be distinguished:

• Goan-origin Portuguese: descendants of families from Goa who moved within the Portuguese world, to Lisbon, Mozambique, Angola and elsewhere. Antonio Costa, whose father, the writer Orlando da Costa, was born in Goa, is the best-known example.
• Gujarati-origin and Daman-Diu families: many Hindu, Muslim and Ismaili families settled in Mozambique under Portuguese rule and moved to Lisbon after Mozambique became independent in 1975.
• Recent migrants: workers, students and professionals who arrived in the 2000s and later, particularly in farming, hospitality and technology.

The community has built institutions that sustain cultural life, including Hindu temples in the Lisbon area and the Ismaili Centre in Lisbon, inaugurated in 1998. These institutions, together with Goan associations, host festivals such as Diwali and Ganesh Chaturthi and provide a bridge to India for Portuguese society.

How strong is trade and investment between India and Portugal?

Trade and investment between India and Portugal is modest in scale compared with India’s trade with larger European economies, but it has grown and has potential beyond the current level. Portugal is a relatively small economy, and the bilateral trade figure has typically been counted in the low billions of US dollars at most.

The strategic case rests on three points. First, Portugal offers lower costs than many Western European capitals, a skilled workforce and a growing start-up ecosystem centred on Lisbon and Porto, which draws Indian technology firms and entrepreneurs. Second, Portuguese ports on the Atlantic seaboard, such as Sines, offer routes into Europe and the Atlantic. Third, Portugal’s language and historical links with Brazil, Angola and Mozambique give Indian companies a possible route into Portuguese-speaking markets.

Wider trade rules are set largely at EU level. India and the EU have been negotiating a trade and investment framework, and Portugal has generally supported closer EU-India economic ties. Tourism is another channel, since Indian travellers visit Lisbon, Porto and the Algarve, and Portuguese visitors come to Goa for heritage and beaches.

What is the role of defence, maritime and strategic cooperation?

Defence, maritime and strategic cooperation between India and Portugal is limited in scale but growing, and it focuses on maritime security, naval exchanges, training and dialogue. Both countries are maritime nations with long coastlines, and both have an interest in the freedom of navigation across the Atlantic and Indian Oceans.

Portugal is a founding member of the North Atlantic Treaty Organization (NATO), while India follows a policy of strategic autonomy and is not a treaty ally of any bloc. This difference shapes the character of defence ties, which lean toward dialogue, port calls, exchanges and cooperation in areas such as maritime domain awareness rather than formal alliances. Portugal also sits at the Atlantic edge of Europe and has an interest in space, ocean science and the blue economy, areas where Indian institutions have capabilities.

The agreements signed in 2017 and in later years opened the way for cooperation in science and technology, including space applications, and for dialogue on cyber security. Both sides see room for further work on counter-piracy, fisheries monitoring and ocean research, and the relationship is expected to stay low-key but steady.

How do culture and heritage connect India and Portugal?

Culture and heritage connect India and Portugal through language, food, architecture, law and religion, with Goa as the central link. The churches and convents of Old Goa, including the Basilica of Bom Jesus, were inscribed on the UNESCO World Heritage List in 1986 and attract visitors from both countries.

Examples of the exchange include:

• Language: Indian languages contain Portuguese loanwords such as almirah (from armario), verandah (from varanda), batata (potato) and balde (bucket), while Konkani and Portuguese have influenced each other in Goa.
• Food: the Portuguese brought chilli, potato, tomato, cashew, pineapple and papaya from the Americas to India, and Goan dishes such as vindaloo derive from the Portuguese vinha d’alhos.
• Law: the Goa Civil Code, rooted in the Portuguese Civil Code, remains in force in Goa and is often cited in debates on a uniform civil code.
• Education and institutions: Indian studies and Indian languages are taught at Portuguese universities, and Portuguese institutions such as the Fundacao Oriente maintain a presence in Goa.

Cultural diplomacy also includes film, music and literature. Lisbon hosts Indian film events, and Portuguese-language scholarship on Goa and the Indian Ocean world continues to develop.

What are the main milestones in India-Portugal relations?

The main milestones in India-Portugal relations run from the arrival of Vasco da Gama in 1498 to the high-level engagement of the 2010s and 2020s. The timeline below gives the key dates.

What is the future of India-Portugal relations?

The future of India-Portugal relations is likely to be defined by closer economic ties through the EU, deeper people-to-people links and cooperation in technology, energy and the blue economy. Several trends support this view.

• EU-India convergence: as the EU and India deepen trade, technology and connectivity ties, Portugal can serve as a supportive voice and a practical hub.
• Green energy: Portugal has a high share of renewable power, particularly wind, hydro and solar, and Indian firms are expanding in green hydrogen and solar manufacturing, creating potential for joint work.
• Digital economy: Lisbon’s start-up scene and India’s digital public infrastructure offer a basis for exchange.
• Diaspora: the Goan and Gujarati communities provide trust, networks and political goodwill on both sides.
• Ocean affairs: shared interests in shipping, fisheries and marine science.

The relationship also faces limits: it is small in economic terms, Portugal’s attention is split across Europe, Africa and Latin America, and migration policy on both sides can change. The challenge is to turn goodwill into concrete projects.

Bottom Line

India-Portugal relations have moved from a contested colonial past to a stable partnership built on the 1974 treaty, strong diaspora ties and shared interests within the EU framework. The relationship is modest in economic weight, but its cultural depth, the Goan link and Portugal’s position as an Atlantic and EU gateway give it lasting value.
