Maharashtra (; Marathi: [məharaːʂʈɾə] (listen), abbr. MH or Maha) is a state in the western peninsular region of India occupying a substantial portion of the Deccan Plateau. Maharashtra is the second-most populous state in India and the second-most populous country subdivision globally. It was formed on 1 May 1960 by splitting the bilingual Bombay State, which had existed since 1956, into majority Marathi-speaking Maharashtra and Gujarati-speaking Gujarat. Maharashtra is home to the Marathi people, the predominant ethno-linguistic group, who speak the Marathi language, the official language of the state. The state is divided into 6 divisions and 36 districts, with the state capital being Mumbai, the most populous urban area in India, and Nagpur serving as the winter capital, which also hosts the winter session of the state legislature. Godavari and Krishna are the two major rivers in the state. Forests cover 16.47 per cent of the state's geographical area. Out of the total cultivable land in the state, about 60 per cent is used for grain crops in the Deccan region, rice in coastal Konkan, and other high rainfall areas. Spread over 307,713 km2 (118,809 sq mi), Maharashtra is the third-largest state by area in India. It is bordered by the Arabian Sea to the west, the Indian states of Karnataka and Goa to the south, Telangana to the southeast and Chhattisgarh to the east, Gujarat and Madhya Pradesh to the north, and the Indian union territory of Dadra and Nagar Haveli and Daman and Diu to the northwest. The state has three international airports, Chhatrapati Shivaji Maharaj International Airport (Mumbai), Dr. Babasaheb Ambedkar International Airport (Nagpur), and Pune Airport. The state is home to three railways headquarters viz. Central Railway (Chhatrapati Shivaji Maharaj Terminus), Konkan Railway (CBD Belapur), and Western Railway (Churchgate). The High Court of the state viz. Bombay High Court is located in Mumbai. The state contributes 48 seats and 19 seats to the lower house Lok Sabha and the upper house Rajya Sabha, respectively. Maharashtra has been subject to President's rule three times since its formation for a total of 156 days for different reasons. More than three-fourths of the population practice Hinduism, which is followed by Islam and Buddhism. The state is home to four UNESCO World Heritage Sites: Ajanta, Ellora and Elephanta caves, and the Chhatrapati Shivaji Maharaj Terminus (formerly Victoria Terminus). Maharashtra is one of the most industrialised states in India. The state's capital, Mumbai, is India's financial and commercial capital. India's largest stock exchange Bombay Stock Exchange, the oldest in Asia, is located in the city. The state has played a significant role in the country's social and political life and is widely considered a leader in terms of agricultural and industrial production, trade and transport, and education. Maharashtra is among the most developed Indian states and continues to be the single largest contributor to the national economy with a share of 14 per cent in all-India nominal GDP. The economy of Maharashtra is the largest in India, with a gross state domestic product (GSDP) of ₹35.81 trillion (US$450 billion) and GSDP per capita of ₹225,073 (US$2,800). The service sector dominates the state's economy, accounting for 69.3 per cent of the value of the output of the country. Although agriculture accounts for 12 per cent of the state GDP, it employs nearly half the population of the state. Maharashtra is the fifteenth-highest ranking among Indian states in the human development index. The region that encompasses the state has a history going back many millennia. Prior to Indian independence, notable dynasties and entities that ruled the region include in a chronologial order, the Maurya, the Western Satraps, the Satavahana dynasty, Rashtrakuta dynasty, Western Chalukyas, the Bahamanis, Deccan sultanates, Mughals, the Maratha Empire founded by Shivaji, and the British. Ruins, monuments, tombs, forts, and places of worship left by these rulers are dotted around the state. At the time of the Indian independence movement in the early 20th century, along with British ruled areas of Bombay presidency, and Central Provinces and Berar, the region included many British Vassal states. Among these, the erstwhile Hyderabad state was the largest and extended over many modern Indian states. Other states grouped under Deccan States Agency included Kolhapur, Miraj, Sangli, Aundh, Bhor, and Sawantwadi.

Mumbai (English: (listen), Marathi: [ˈmumbəi]; also known as Bombay — the official name until 1995) is the capital city of the Indian state of Maharashtra and the de facto financial centre of India. According to the United Nations, as of 2018, Mumbai is the second-most populous city in India after Delhi and the eighth-most populous city in the world with a population of roughly 2 crore (20 million). As per the Indian government population census of 2011, Mumbai was the most populous city in India with an estimated city proper population of 1.25 crore (12.5 million) living under the Brihanmumbai Municipal Corporation. Mumbai is the centre of the Mumbai Metropolitan Region, the sixth most populous metropolitan area in the world with a population of over 2.3 crore (23 million). Mumbai lies on the Konkan coast on the west coast of India and has a deep natural harbour. In 2008, Mumbai was named an alpha world city. It has the highest number of millionaires and billionaires among all cities in India.The seven islands that constitute Mumbai were earlier home to communities of Marathi language speaking Koli people. For centuries, the seven islands of Bombay were under the control of successive indigenous rulers before being ceded to the Portuguese Empire, and subsequently to the East India Company in 1661, through the dowry of Catherine Braganza when she was married off to Charles II of England. During the mid-18th century, Bombay was reshaped by the Hornby Vellard project, which undertook reclamation of the area between the seven islands from the sea. Along with construction of major roads and railways, the reclamation project, completed in 1845, transformed Bombay into a major seaport on the Arabian Sea. Bombay in the 19th century was characterised by economic and educational development. During the early 20th century it became a strong base for the Indian independence movement. Upon India's independence in 1947 the city was incorporated into Bombay State. In 1960, following the Samyukta Maharashtra Movement, a new state of Maharashtra was created with Bombay as the capital.Mumbai is the financial, commercial, and the entertainment capital of India. It is also one of the world's top ten centres of commerce in terms of global financial flow, generating 6.16% of India's GDP, and accounting for 25% of industrial output, 70% of maritime trade in India (Mumbai Port Trust and JNPT), and 70% of capital transactions to India's economy. Mumbai has the eighth-highest number of billionaires of any city in the world, and Mumbai's billionaires had the highest average wealth of any city in the world in 2008. The city houses important financial institutions and the corporate headquarters of numerous Indian companies and multinational corporations. It is also home to some of India's premier scientific and nuclear institutes. The city is also home to Bollywood and Marathi cinema industries. Mumbai's business opportunities attract migrants from all over India.
