Vasai Through the Ages: From Ancient Sopara to Portuguese Baçaim and Beyond
Introduction
The Vasai-Virar region has undergone enormous change, particularly since the 1980s, when a rapid influx of people was encouraged by the availability of housing that was generally more affordable than in Mumbai, formerly known as Bombay.
Yet beneath today’s rapidly growing urban landscape lies a history that stretches back many centuries. The wider region around Vasai was part of an important network of settlements and ports on India’s western coast. Ancient Sopara, nearby, was an important trading centre, while Kalyan and Thane also played significant roles at different periods. Archaeological remains, including Buddhist rock-cut sites in the Salsette region, provide evidence of communities living in the area from at least the first millennium BCE.
Among all the periods in Vasai’s history, the two centuries of Portuguese rule left perhaps the most visible and enduring legacy. From 1534 to 1739, the Portuguese transformed Baçaim into the political and religious centre of their Northern Province. They built a fortified city, churches, convents, administrative buildings and residences, while incorporating the surrounding villages and agricultural lands into their colonial system.
Today, the ruins of Vasai Fort and its churches remain among the most remarkable surviving examples of Portuguese urban and religious architecture in India.
Vasai Before the Portuguese
Long before the arrival of the Portuguese, the region was connected to the wider maritime trade of western India.
The nearby ancient port of Sopara, identified with present-day Nalasopara, was an important centre of trade and religious activity. Kalyan and Thane also played significant roles at different times. By the beginning of the Portuguese period, however, Thane had declined in importance relative to Baçaim, which had emerged as an important political centre in the region.
The territory was associated with the Sultanate of Gujarat when the Portuguese began their expansion along the western coast. Baçaim itself enjoyed a considerable degree of local autonomy within the Sultanate.
The origin and evolution of the name Vasai are subjects of historical discussion. The Portuguese called the settlement Baçaim; English sources subsequently used forms such as Bassein, while Vasai became the modern Marathi and English name.
The region’s geographical position made it valuable. Its resources included fertile agricultural land, rice, coconut and other crops, timber, salt, fisheries and stone. Its proximity to the sea also made it strategically important for maritime commerce and military operations.
The Portuguese Arrive
When the Portuguese began establishing their power on India’s western coast, the region was under the authority of Bahadur Shah, Sultan of Gujarat.
Portuguese naval expeditions attacked settlements along the coast in the early 1530s. These attacks were part of a larger Portuguese effort to control maritime trade and establish strategic bases along the western coast of India.
In 1533, Portuguese forces under Diogo de Silveira conducted a major campaign along the coast, including the area around Thane and Baçaim. Contemporary accounts describe extensive destruction and the taking of captives. Such accounts should be read in the context of the violent military and commercial expansion of the Portuguese Estado da Índia.
The Portuguese were particularly interested in securing Diu, a strategically important port, and in establishing control over the approaches to Gujarat and the Arabian Sea.
The Treaty of Baçaim — 1534
The decisive turning point came on 23 December 1534, when Sultan Bahadur Shah of Gujarat entered into a treaty with the Portuguese and ceded Baçaim and its dependencies to Portugal.
The territory transferred included Baçaim and a number of surrounding islands and settlements, including Salsette and the islands associated with present-day Mumbai. This gave Portugal control over a strategically important portion of the western coast.
The acquisition of Baçaim was enormously important to the Portuguese Estado da Índia. Baçaim became the centre of a large territory and developed into the principal Portuguese settlement of the Northern Province.
The Portuguese presence in the region ultimately lasted approximately 205 years, from 1534 until 1739.
The Rise of Portuguese Baçaim
Following the Portuguese acquisition of Baçaim, the settlement developed into an important administrative, commercial and religious centre.
Garcia de Sá became one of the earliest Portuguese captains of Baçaim and later served as Governor of Portuguese India. Jorge Cabral, who succeeded him, also later became Governor of Portuguese India.
During the sixteenth and seventeenth centuries, the Portuguese expanded their control over surrounding villages and agricultural lands. Existing settlements and landholding systems were incorporated into the Portuguese colonial administration, while new forts, churches and other structures were established. Modern historical research has emphasized that Portuguese Baçaim was not simply a military fort but a substantial urban and territorial centre.
The Fortress of Baçaim
During the second half of the sixteenth century, the Portuguese developed the great fortress that came to dominate Baçaim.
The fortified city enclosed not only military installations but also churches, convents, residences and other buildings. It became a substantial walled urban settlement.
The fortifications contained numerous bastions and gateways, including the Porta do Mar, or Sea Gate, which opened toward the water, and the landward entrance known as the Porta da Terra.
Among the surviving features of the fort are the massive walls, bastions, gateways, churches, convents, residences and numerous stone inscriptions and tombstones.
The remains provide an unusually vivid picture of a Portuguese colonial city in India. The Heritage of Portuguese Influence in India describes Baçaim as one of the rare Portuguese-founded or Portuguese-structured cities in the East whose urban importance lasted for centuries.
Churches and Christianity
Religion played a central role in Portuguese Baçaim.
Missionaries established churches and religious institutions throughout the Northern Province, and Baçaim itself became home to several religious orders.
Within the fort today are the remains of several major religious complexes, including those associated with the Franciscans, Augustinians, Dominicans, Jesuits and Hospitallers. There was also a parish church and other religious buildings.
Outside the fort and throughout the surrounding territory, churches were established in villages including Nirmal, Manikpur, Sandor, Agashi, Nandakhal, Papdy, Pali and other settlements.
The conversion of sections of the local population to Christianity was an important part of Portuguese missionary activity. At the same time, the history of conversion was complex and involved missionaries, local communities, landholding arrangements, Portuguese political authorities and changing social conditions.
It is therefore important to view the Christian history of Vasai not simply as a story of Portuguese rule, but also as the history of local communities that developed their own traditions and identities over the centuries.
Baçaim — The Court of the North
As Portuguese power expanded, Baçaim became known as “a Corte do Norte,” or “the Court of the North.”
It became the administrative and social centre of the Portuguese Northern Province and attracted Portuguese officials, soldiers, clergy, landowners and merchants.
Contemporary descriptions portray Baçaim as a prosperous city with substantial houses, churches and religious institutions. Portuguese families of considerable wealth lived in the city, and the settlement became associated with Portuguese aristocratic culture in India.
A description from the seventeenth century refers to the city’s wealthy residents and substantial two-storey houses with balconies and large windows. Modern architectural research confirms that the residential architecture of the region developed distinctive features combining Portuguese and local traditions.
The expression “Fidalgo de Baçaim” became associated with the status and reputation of the city’s Portuguese elite.
The Economy of Portuguese Baçaim
The territory surrounding Baçaim was agriculturally productive.
Rice, coconut and other crops were cultivated extensively, while the region also benefited from fisheries, salt production, timber, stone and maritime commerce.
The Portuguese incorporated existing villages and agricultural systems into their colonial administration. Land grants and other arrangements helped create a network of estates and settlements that supported the Portuguese military and administrative presence.
Baçaim therefore served simultaneously as:
- a fortified military centre;
- an administrative capital;
- a religious centre;
- a commercial settlement;
- and the centre of a productive agricultural territory.
Research into Portuguese Baçaim has shown that Portuguese rule involved both the incorporation of existing settlements and the creation of new territorial and urban structures.
The Mint and Portuguese Coins
Baçaim also had a mint, known as the Casa da Moeda.
Portuguese coins from the period have occasionally been found in the region, and old Portuguese coins became locally associated with the term “Firgi paisa.”
The existence of a mint reflects the importance of Baçaim within the economic and administrative structure of Portuguese India.
The Catastrophe of 1618
In 1618, Baçaim suffered a series of disasters.
Contemporary accounts describe disease followed by a devastating storm on 15 May 1618. The storm caused severe damage to houses and boats and uprooted large numbers of coconut trees. Seawater entered the city, while churches, monasteries and convents suffered extensive damage.
The storm was followed by a severe failure of the monsoon, creating famine conditions.
Historical accounts describe extreme hardship, including reports that some parents resorted to selling children because of starvation. Jesuit missionaries and wealthy benefactors are reported to have provided assistance to those affected.
The scale of this disaster illustrates the vulnerability of the city and its population to extreme weather, disease and failures of the agricultural economy.
Modern research confirms that the 1618 catastrophe caused significant damage to Baçaim’s religious and urban infrastructure, although the precise extent of damage to individual buildings remains a subject of historical investigation.
Baçaim in the Seventeenth Century
Despite disasters, Baçaim recovered and continued to prosper.
Seventeenth-century descriptions portray a city with Portuguese families, Indian Christian communities, religious institutions and an increasingly complex social structure.
By the middle and later decades of the seventeenth century, Baçaim had become one of the most important Portuguese cities in India after Goa and Cochin. The surviving architecture reflects the wealth and influence of the Portuguese elite and Catholic religious orders.
The city’s importance was not limited to the walls of the fort. Portuguese authority extended over a much larger territory containing villages, agricultural lands, churches and smaller fortifications.
The Changing Balance of Power
During the seventeenth century, Portuguese power in western India gradually faced increasing challenges.
The emergence of the Marathas as a major regional power created a powerful land-based rival to Portuguese possessions. At sea, the Portuguese faced competition from other European powers and maritime forces, including Omani fleets.
The transfer of Bombay to the English was particularly significant.
Bombay formed part of the dowry of Catherine of Braganza, the Portuguese princess who married Charles II of England. Although the marriage treaty dates to 1661, the actual transfer of Bombay was completed in 1665. The transfer placed an increasingly powerful English presence immediately adjacent to Portuguese territory.
From this point onward, Portuguese Baçaim faced growing strategic pressure from both the Marathas and the English.
Portuguese Administration and Its Problems
Portuguese rule brought significant changes to the region, but it also had serious limitations.
Land was granted to individuals and religious institutions under various systems of tenure. The administration depended heavily on a relatively small colonial elite, while military and administrative resources were often limited.
The Portuguese also pursued an active Catholic missionary policy. Religious intolerance and conflicts with non-Christian communities contributed to tensions in parts of Portuguese India.
The establishment of the Goa Inquisition in 1560 became one of the most controversial aspects of Portuguese religious policy, although its direct effects varied considerably between territories.
The union of the Portuguese and Spanish crowns from 1580 to 1640 further complicated Portuguese administration and resources in Asia.
By the eighteenth century, Portuguese power had declined considerably compared with the previous century.
The Maratha Expansion
The rise of the Maratha state transformed the political landscape of western India.
The Marathas captured Kalyan in the early eighteenth century and subsequently expanded their control over territory surrounding the Portuguese Northern Province.
In 1737, Maratha forces captured Thane and much of Salsette. A number of smaller Portuguese forts and positions also fell.
By 1738, the Portuguese were increasingly isolated.
The remaining Portuguese possessions in the Northern Province included Baçaim and a number of smaller settlements and fortifications, including areas around Mahim, Kelve, Shirgaon, Tarapur, Asheri, Dahanu, Caranja and Daman.
The Portuguese position had become increasingly difficult to defend.
The Fall of Baçaim — 1739
The final campaign against Baçaim was led by Chimaji Appa, the younger brother of Peshwa Baji Rao I.
The Marathas first captured a series of Portuguese positions around the Northern Province before concentrating their forces against Baçaim.
The siege of Baçaim began in February 1739 and continued for several months.
The Portuguese defenders resisted strongly, while the Marathas constructed trenches and mines to approach and breach the fortifications.
The siege was particularly difficult because Baçaim was a major fortified city with substantial defensive works and artillery.
Eventually, after sustained fighting and the destruction of sections of the fortifications, the Portuguese position became untenable.
On 16 May 1739, the Portuguese commander Caetano de Sousa Pereira agreed to the terms of surrender with Chimaji Appa. The surviving surrender document is an important primary source for the final days of Portuguese Baçaim. It records the conditions under which the Portuguese garrison would leave and contains provisions concerning people, property and religious institutions.
The surrender brought approximately two centuries of Portuguese rule in Baçaim to an end. Portuguese control of the territory had lasted from 1534 to 1739.
The Portuguese Departure
The surrender terms allowed the Portuguese garrison to leave with military honours and permitted those departing to take movable property within the agreed period.
The surrender document also contains provisions concerning churches and religious objects, demonstrating that the transfer of the city was governed by negotiated terms rather than being simply an uncontrolled destruction of the Portuguese population.
The end of Portuguese rule nevertheless marked a profound transformation.
Baçaim ceased to be the centre of Portuguese power in the Northern Province, and the city gradually lost much of its former political and commercial importance.
From Baçaim to Vasai
After the Maratha conquest, the region entered a new political era.
Some Portuguese buildings and churches were damaged, abandoned or repurposed, while other religious sites continued to serve local Christian communities.
Stories concerning church bells removed from Baçaim and later installed at temples elsewhere in Maharashtra have become part of local historical tradition. Such stories are important elements of Vasai’s cultural memory, although individual bells and their histories should be documented separately before specific identifications are presented as established fact.
The former Portuguese city gradually became a place of ruins, agricultural settlement and local pilgrimage rather than the major political centre it had once been.
The British and the Changing Political Landscape
The British became increasingly influential in western India during the eighteenth century.
Bassein changed hands during the conflicts between the British and the Marathas associated with the First Anglo-Maratha War. British military forces occupied the fort in 1774, and the political circumstances surrounding the occupation and subsequent Maratha restoration need to be understood within the wider Anglo-Maratha conflict.
The British again captured Bassein in 1780, after a campaign led by Colonel Thomas Goddard during the Second Anglo-Maratha War.
The changing ownership of Bassein reflected the larger transformation taking place throughout western India as the East India Company expanded its military and political influence.
The Treaty of Bassein — 1802
Perhaps the most famous event in Bassein’s later history occurred in 1802.
Peshwa Baji Rao II was defeated by the forces of Yashwantrao Holkar and sought British assistance.
On 31 December 1802, Baji Rao II signed the Treaty of Bassein with the British East India Company.
This treaty was a major turning point in Indian history.
Under its terms, the Peshwa accepted a permanent British military force of approximately 6,000 troops and agreed to provide territory whose revenues would support the force. He also accepted restrictions on his ability to conduct independent foreign relations and warfare.
The treaty restored Baji Rao II to Poona under British protection in 1803.
The Treaty of Bassein contributed directly to the expansion of British influence over the Maratha Confederacy and played a major role in the events leading to the Second Anglo-Maratha War.
It is important to distinguish this 1802 Treaty of Bassein from the 1534 Treaty of Baçaim, even though both are associated with the same historic city.
The Railway Era
The nineteenth century brought another transformation.
As Bombay developed into a major commercial and industrial centre, the surrounding region became increasingly connected to the city.
Railway development transformed the movement of people and goods through the Vasai-Virar region. Stations serving the area included Naigaon, Bassein, Nalasopara and Virar.
The expansion of railway and steamship connections strengthened the integration of the region into the economic life of Bombay.
By the twentieth century, the old Portuguese city of Bassein had become increasingly overshadowed by the rapidly expanding Bombay metropolitan region.
The Legacy of Portuguese Baçaim
Today, Vasai Fort stands as one of the most important surviving monuments of the Portuguese period in India.
Within its walls are the remains of churches, convents, residential buildings, defensive walls, bastions, gateways, wells, inscriptions and tombstones.
The ruins provide an extraordinary record of the meeting of Portuguese and Indian cultures.
The architectural legacy is particularly significant. Portuguese churches and houses were adapted to the local climate and materials, while local communities incorporated elements of Portuguese architecture, language, religion and culture into their own traditions.
Modern research has identified Baçaim as one of the most important Portuguese urban centres in India and emphasizes the lasting impact of the Portuguese territorial system on the later development of the Mumbai metropolitan region.
Vasai Today
Modern Vasai is very different from the fortified Portuguese city of Baçaim.
The Vasai-Virar region has become a major urban and residential area, connected closely to Mumbai by road and rail. New housing, commercial development and population growth have transformed the landscape dramatically.
Yet the older layers of history remain visible.
The churches, villages, traditional houses, agricultural landscapes and ruins of Vasai Fort preserve memories of a region shaped successively by ancient Indian communities, regional kingdoms, the Sultanate of Gujarat, the Portuguese, the Marathas and the British.
For the people of Vasai, this history is more than a record of political changes. It is part of the cultural identity of the region.
The Portuguese period, in particular, left a legacy that can still be seen in architecture, surnames, food, music, language, religious traditions and village life.
A Living Historical Heritage
Vasai should therefore not be understood simply as the location of a ruined Portuguese fort.
It is a landscape in which many histories overlap.
Ancient Sopara and the early maritime networks of western India form one layer. The medieval history of Gujarat and the Deccan forms another. Portuguese Baçaim created a fortified city and a vast territorial system. The Maratha conquest transformed the political order, while British expansion brought the region into an increasingly interconnected colonial economy.
The descendants of the communities who lived through these changes continue to preserve many traditions today.
The churches and ruins of Vasai Fort, the villages surrounding them, local music, family histories, traditional festivals and oral memories all form part of the region’s historical heritage.
Preserving these stories—and documenting them carefully—is essential if future generations are to understand how modern Vasai came to be.
