It is the state's primate city both in area and population and is located on the Coromandel Coast of the Bay of Bengal. According to the 2011 Indian census, Chennai is the sixth-most populous city in India and forms the fourth-most populous urban agglomeration. Incorporated in 1866, the Greater Chennai Corporation is the oldest municipal corporation of India and the second oldest in the world after London. Historically, Chennai and surroundings were part of the Chola, Pandya, Pallava and Vijayanagara kingdoms for many centuries. The coastal land, which then contained the fishing village Madrasapattinam, was purchased by the British East India Company from the Nayak ruler Damarla Chennapa Nayaka, in the 17th century. The British garrison established the Madras city and port, and built Fort St. George—the first British fortress in India—which the French won over briefly in 1746, before becoming the winter capital of the Madras Presidency, a colonial province of the British Raj in the Indian subcontinent. After India gained its independence in 1947, Madras continued as the capital city of the Madras State and present-day Tamil Nadu. The city was officially renamed as Chennai in 1996.

It has a population of more than 8 million and a metropolitan population of around 11 million, making it India's third most populous city and fifth most populous urban agglomeration, as well as South India's second-largest urban agglomeration, and the 27th largest city in the world.[10] Located on the Deccan Plateau, at a height of over 900 m (3,000 ft) above sea level, Bangalore has a pleasant climate throughout the year, with its parks and green spaces earning it the reputation of India's "Garden City".[11] Its elevation is the highest among India's major cities.[12] The city's history dates back to around 890, as found in a stone inscription found at the Nageshwara Temple in Begur, Bangalore. In 1537, Kempé Gowdā, a feudal ruler under the Vijayanagara Empire, established a mud fort, considered the foundation of modern Bangalore and its oldest areas, or pétés, which still exist. After the fall of the Vijayanagara Empire, Kempe Gowda declared independence; in 1638, a large Adil Shahi Bijapur army defeated Kempe Gowda III, and Bangalore came under Shahaji Bhonsle as a jagir, which later became his capital. The Mughals later captured Bangalore and sold it to Maharaja Devaraja Wodeyar II of the Kingdom of Mysore.[13] When Haider Ali seized control of the kingdom, Bangalore's administration passed into his hands.

It lies on the eastern bank of the Hooghly River, 80 km (50 mi) west of the border with Bangladesh. It is the primary financial and commercial center of eastern and northeastern India.[16] Kolkata is the seventh most populous city of India with an estimated city proper population of 4.5 million (0.45 crore).[17] It is the centre of the Kolkata Metropolitan Region, one of the most populous metropolitan area in the world with a population of over 15 million (1.5 crore) residents. Kolkata is the de facto cultural capital of India and historically and culturally significant city in the historic region of Bengal.[1][18][19] It is the second largest Bengali-speaking city in the world. It has the highest number of nobel laureates among all cities in India. The three villages that predated Calcutta were ruled by the Nawab of Bengal under Mughal suzerainty. After the Nawab granted the East India Company a trading licence in 1690,[20] the area was developed by the Company into Fort William. Nawab Siraj ud-Daulah occupied the fort in 1756 but was defeated at the Battle of Plassey in 1757, after his general Mir Jafar mutinied in support of the Company, and was later made the Nawab for a brief time.[21] Under company and later crown rule, Calcutta served as the de facto capital of India until 1911. Calcutta was the second largest city in the British Empire, after London.[22] and was the center of bureaucracy, politics, law, education, science and the arts in India. The city was associated with many of the figures and movements of the Bengali Renaissance. It was the hotbed of the Indian nationalist movement.[23] The University of Calcutta and its affiliated colleges produced many leading figures of South Asia. Kolkata's architecture includes many imperial landmarks, including the Victoria Memorial, Howrah Bridge and the Grand Hotel. The city's heritage includes India's only Chinatown and remnants of Jewish, Armenian, Greek and Anglo-Indian communities. The city is closely linked with Bhadralok culture and the Zamindars of Bengal, including Bengali Hindu, Bengali Muslim and tribal aristocrats. The partition of Bengal affected the fortunes of the city. In the late 20th century, the city hosted the government-in-exile of Bangladesh during the Pakistani Civil War in 1971;[24] it built India's first subway; and it was overtaken by Mumbai (formerly Bombay) as India's largest city. The Port of Kolkata is India's oldest operating port. The city is often regarded as India's cultural capital.

It occupies 650 km2 (250 sq mi) on the Deccan Plateau along the banks of the Musi River, in the northern part of Southern India. With an average altitude of 542 m (1,778 ft), much of Hyderabad is situated on hilly terrain around artificial lakes, including the Hussain Sagar lake, predating the city's founding, in the north of the city centre. According to the 2011 Census of India, Hyderabad is the fourth-most populous city in India with a population of 6.9 million residents within the city limits, and has a population of 9.7 million residents in the metropolitan region, making it the sixth-most populous metropolitan area in India. With an output of US$74 billion, Hyderabad has the fifth-largest urban economy in India. The Qutb Shahi dynasty's Muhammad Quli Qutb Shah established Hyderabad in 1591 to extend the capital beyond the fortified Golconda. In 1687, the city was annexed by the Mughals. In 1724, Asaf Jah I, the Mughal viceroy, declared his sovereignty and founded the Asaf Jahi dynasty, also known as the Nizams. Hyderabad served as the imperial capital of the Asaf Jahi's from 1769 to 1948. As capital of the princely state of Hyderabad, the city housed the British Residency and cantonment until Indian independence in 1947. Hyderabad was annexed by the Indian Union in 1948 and continued as a capital of Hyderabad State from 1948 to 1956. After the introduction of the States Reorganisation Act of 1956, Hyderabad was made the capital of the newly formed Andhra Pradesh. In 2014, Andhra Pradesh was split to form the state of Telangana, and Hyderabad became the joint capital of the two states with a transitional arrangement scheduled to end in 2024. Since 1956, the city has housed the Rashtrapati Nilayam, the winter office of the president of India. Relics of the Qutb Shahi and Nizam eras remain visible today; the Charminar has come to symbolise the city. By the end of the early modern era, the Mughal Empire had declined in the Deccan, and the Nizam's patronage attracted men of letters from various parts of the world. A distinctive culture arose from the amalgamation of local and migrated artisans, with Painting, handicraft, jewellery, literature, dialect and clothing are prominent still today. Through its cuisine, the city is listed as a creative city of gastronomy by UNESCO. The Telugu film industry based in the city is the highest-grossing film industry in India as of 2021. Until the 19th century Hyderabad was known for the pearl industry and was nicknamed the "City of Pearls", and was the only trading centre for Golconda diamonds in the world. Many of the city's historical and traditional bazaars remain open. Hyderabad's central location between the Deccan Plateau and the Western Ghats, and industrialisation throughout the 20th century attracted major Indian research, manufacturing, educational and financial institutions. Since the 1990s, the city has emerged as an Indian hub of pharmaceuticals and biotechnology and information technology. The formation of the special economic zones of Hardware Park and HITEC City, dedicated to information technology, has encouraged leading multinationals to set up operations in Hyderabad.
