Historical Background

As we mention earlier that Mumbai is built on seven islands. It is not exactly known when these islands were first time inhabitated by human, but the Pleistocene sediments found along the coastal areas around Kandivali in northern Mumbai suggest that the islands were inhabitated by humans since hundreds of thousands of years. The Koli, an aboriginal tribe of fishermen, were the earliest known inhabitants of present-day Mumbai. 

Between the second century BCE and ninth century CE, the islands came under the control of successive indigenous dynasties: Satavahanas, Western Satraps, Abhira, Vakataka, Kalachuris, Mauryas, Chalukyas and Rashtrakutas, before being ruled by the Shilaharas from 810 to 1260.  Some of oldest edifices built during this period are the Jogeshwari Caves (between 520 and 525),Elephanta Caves (between the sixth to seventh century),Walkeshwar Temple (10th century), and Banganga Tank (12th century). The Mahakali caves in Andheri were cut during the 1 century BCE to 6th century. During 6th-8th century the city was ruled by the Chalukyas who left their mark on elephanta islands.

Mumbai Historical Places

In the 13th century, King Bhimdev founded his kingdom and established his capital Mahikawati(Mahim). During 1347-48 City was annexed by the Delhi Sultanate and they controlled the city until 1407. During this time, the islands were administered by the Governors of Gujarat, who were appointed by the Delhi Sultanate. The islands were later governed by the independent Gujarat Sultanate, which was established in 1407. They established many mosques during their Sultanate. From 1429 to 1431, the islands were a source of contention between the Gujarat Sultanate and the Bahmani Sultanate of Deccan.

In 1526 the Mughal empire was founded and in the mid-16th century it became the dominant power in the Indian Subcontinent. Due to growing apprehensive of the power of the Mughal emperor Humayun, Sultan Bahadur Shah of Gujarat was obliged to sign the Treaty of Bassein with the Portuguese Empire on 23 December 1534.  According to the treaty the seven islands were offered to the Portuguese. The territories were later surrendered on 25 October 1535. The Portuguese were actively involved in the foundation and growth of their Roman Catholic religious orders in Bombay.They called the islands by various names, which finally took the written form Bombaim. They made many Churches, some popular churches are the St. Michael’s Church at Mahim (1534), St. John the Baptist Church at Andheri (1579), St. Andrew’s Church at Bandra (1580), and Gloria Church at Byculla (1632). The Portuguese also built several fortifications around the city like the Bombay Castle, Castella de Aguada (Castelo da Aguada or Bandra Fort), and Madh Fort.

On 11 May 1661, the marriage treaty of Charles II of England and Catherine of Braganza, daughter of King John IV of Portugal, placed the islands in possession of the English Empire, as part of Catherine’s dowry to Charles. However, Salsette, Bassein, Mazagaon, Parel, Worli, Sion, Dharavi, and Wadala still remained under Portuguese possession. From 1665 to 1666, the English managed to acquire Mahim, Sion, Dharavi, and Wadala. In 1687 East India Company transferred their headquarters from Surat to Bombay. It became the headquarter of the Bombay presidency. In 1737 Peshwa Bajirao 1 captured Salsette, and Basseun in 1739, ending the presence of Portuguese in the Mumbai. By the middle of the 18th century, Bombay began to grow into a major trading town, and received a huge influx of migrants from across India. In 1775, British occupied the Salsette and Bassein with the treaty of Surat, resulting in first Anglo-Maratha War.

From 1782 onwards, the city was reshaped with large-scale civil engineering projects aimed at merging all the seven islands of Bombay into a single amalgamated mass by using a causeway called the Hornby Vellard, which was completed by 1784. In 1817 the last peshwa of Maratha Bajirao 2 was defeated in the battle of Khadki by the British. After this victory, almost the whole of the Deccan Plateau came under British suzerainty, and was incorporated into the Bombay Presidency.

First Train in India, Mumbai to Thane
The first railway was established between Mumbai and Thane on 16 April 1853.

By 1845, the seven islands coalesced into a single landmass by the Hornby Vellard project via large scale land reclamation. The first railway was established between Mumbai and Thane on 16 April 1853. From 1862 to 1865, the city became the world’s chief cotton trading market, resulting in a boom in the economy. While the city was capital of the Bombay Presidency, Indian independence movement fostered the Quit India Movement in 1942 and the mutiny of Royal Indian Navy in 1946.

After India’s independence in 1947, the territory of the Bombay Presidency retained by India was restructured into Bombay State. In 1950 Bombay was declared state, following protests of Samyukta Maharashtra Movement, in which 107 people were killed by police. Bombay State was reorganised on linguistic lines.

Bombay State

Gujarati-speaking areas of Bombay State were partitioned into the state of Gujarat following the Mahagujarat Movement. Maharashtra State with Bombay as its capital was formed with the merger of Marathi-speaking areas of Bombay State, eight districts from Central Provinces and Berar, five districts from Hyderabad State, and numerous princely states enclosed between them.

The following decades saw massive expansion of the city and its suburbs. In the late 1960s, Nariman Point and Cuffe Parade were reclaimed and developed. On 26th January 1975 by the government of Maharashtra, The Bombay Metropolitan Region Development Authority (BMRDA) was established as an apex body for planning and co-ordination of development activities in Bombay metropolitan region. In August 1979, a sister township of New Bombay was found by the City and Industrial Development Corporation (CIDCO) across the Thane and Raigad districts to help the dispersal and control of Bombay’s population. The Jawaharlal Nehru Port was commissioned on 26 May 1989 across the creek at Nhava Sheva with a view to de-congest Bombay Harbour and to serve as a hub port for the city. On 1 October 1990 Mumbai was divided into two districts that are Mumbai city and Mumbai suburban.

In March 1993, a series of 13 coordinated bombings at several city landmarks by extremists and the Bombay underworld resulted in 257 deaths and over 700 injuries. The city also suffered a series of seven bomb explosions in the city’s commuter trains, in 2006 which resulted in deaths of 209 people and over 700 injured .

Environmental issues.

Pollution, growing population and lack of space are regarded as the traditional challenges of Mumbai. But in the previous two decades these three challenges along with the rapid development. The floods of 2005, abnormal summer temperatures, erratic rainfalls and the recent landslide on Western Express Highway near Kandivali are undoubtedly the result of environmental degradation of Mumbai. 


There are five water bodies in Maharashtra which are considered as heavily polluted and Mumbai’s Mithi river is one of them. As per the water analysis done by Maharashtra Pollution Control Board (MPCB) in 2018, Mumbai has nine locations which have polluted water which includes popular tourist spots such as Juhu, Nariman point, Worli sea face, Haji Ali and many others.


Another grave threat is air pollution. Mumbai has very high incidence of respiratory problems due to high air pollution in the metropolis. The prime causes behind this are the industries of Eastern suburbs and Navi Mumbai, garbage burning and lack of control over vehicle emmisons.


Noise pollution is also an alarming problem in Mumbai. Heavy traffic, large numbers of railways, aeroplanes, public gatherings and industries are major contributors to noise pollution. According to an exercise conducted to map noise levels across the city CSMT was the nosiest location during the day at 95.3 decibels(dB).

Other Problems

Garbage is another great environmental issue in Mumbai. Approximately, 437.7 of area along the coastline and creeks is under threat with plastic waste. Dharavi which is one of the world’s largest slum areas is also present in Mumbai. Open sewers and lack of proper water supply has led to the spread of diseases in this region. Many dwellers in Dharavi have their settlements around huge garbage dumping. The sanitation facilities are detoriated to such an extent that there is only 1 toilet per 1440 people. Another grave incident was cutting of trees in Aarey forest which is a no-development and eco-sensitive zone, fortunately the Supreme Court’s stay order prevented this heavy demolition of trees.
