It had a population of over 91 million inhabitants within an area of 88,752 km (34,267 sq mi) as of 2011. The population estimate as of 2023 is 99,723,000. West Bengal is the fourth-most populous and thirteenth-largest state by area in India, as well as the eighth-most populous country subdivision of the world. As a part of the Bengal region of the Indian subcontinent, it borders Bangladesh in the east, and Nepal and Bhutan in the north. It also borders the Indian states of Jharkhand, Odisha, Bihar, Sikkim and Assam. The state capital is Kolkata, the third-largest metropolis, and seventh largest city by population in India. West Bengal includes the Darjeeling Himalayan hill region, the Ganges delta, the Rarh region, the coastal Sundarbans and the Bay of Bengal. The state's main ethnic group are the Bengalis, with the Bengali Hindus forming the demographic majority.

The area's early history featured a succession of Indian empires, internal squabbling, and a tussle between Hinduism and Buddhism for dominance. Ancient Bengal was the site of several major Janapadas, while the earliest cities date back to the Vedic period. The region was part of several ancient pan−Indian empires, including the Vangas, Mauryans, and the Guptas. The citadel of Gauḍa served as the capital of the Gauda kingdom, the Pala Empire, and the Sena Empire. Islam was introduced through trade with the Abbasid Caliphate, but following the Ghurid conquests led by Bakhtiyar Khalji and the establishment of the Delhi Sultanate, the Muslim faith spread across the entire Bengal region. During the Bengal Sultanate, the territory was a major trading nation in the world, and was often referred by the Europeans as the "richest country to trade with". It was absorbed into the Mughal Empire in 1576. Simultaneously, some parts of the region were ruled by several Hindu states, and Baro-Bhuyan landlords, and part of it was briefly overrun by the Suri Empire. Following the death of Emperor Aurangzeb in the early 1700s, the proto-industrialised Mughal Bengal became a semi-independent state under the Nawabs of Bengal, and showed signs of the first Industrial Revolution. The region was later annexed into the Bengal Presidency by the British East India Company after the Battle of Buxar in 1764. From 1772 to 1911, Calcutta was the capital of all of East India Company's territories and then the capital of the entirety of India after the establishment of the Viceroyalty. From 1912 to India's Independence in 1947, it was the capital of the Bengal Province.

It occupies 650 km (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 536 m (1,759 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.

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 Jahis from 1769 to 1948. As the 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 until 2024. Since 1956, the city has housed the Rashtrapati Nilayam, the winter office of the president of India.

The Malayali people (Malayalam: [mɐlɐjaːɭi]; also spelt Malayalee and sometimes known by the demonym Keralite) are a Dravidian ethnic group native to the southern Indian state of Kerala, and the union territory of Lakshadweep. They are predominantly native speakers of the Malayalam language, one of the eleven classical languages of India. The state of Kerala was created in 1956 through the States Reorganisation Act. Prior to that, since the 1800s existed the Kingdom of Cochin, the Travancore, Malabar District, and South Canara of the British Raj. The Malabar District was annexed by the British Indians through the Third Mysore War (1790–92) from Tipu Sultan. Before that, the Malabar District was under various kingdoms including the Zamorins of Calicut, Kingdom of Tanur, Arakkal kingdom, Kolathunadu, Valluvanad and Palakkad Rajas.

According to the Indian census of 2011, there are approximately 33 million Malayalis in Kerala, making up 97% of the total population of the state. Malayali minorities are also found in the neighboring state of Tamil Nadu, mainly in Kanyakumari district and Nilgiri district and Dakshina Kannada and Kodagu districts of Karnataka and also in other metropolitan areas of India. Over the course of the later half of the 20th century, significant Malayali communities have emerged in Persian Gulf countries, including the United Arab Emirates (UAE), Bahrain, Saudi Arabia, Oman, Qatar and Kuwait and to a lesser extent, other developed nations with a primarily immigrant background such as Malaysia, Singapore, the United States (US), the United Kingdom (UK), Australia, New Zealand and Canada. As of 2013, there were an estimated 1.6 million ethnic Malayali expatriates worldwide. The estimated population of Malayalees in Malaysia in year 2020 is approximately 348,000, which makes up 12.5% of the total number of Indian population in Malaysia that makes them the second biggest Indian ethnic group in Malaysia, after the Tamils. Most of the Malayalee population in Malaysia aged 18 to 30 are known to be either the third, fourth, or fifth generation living as a Malaysian citizen. According to A. R. Raja Raja Varma, Malayalam was the name of the place, before it became the name of the language spoken by the people.
