Gujarat (, Gujarati: [ˈɡudʒəɾɑt] (listen)) is a state along the western coast of India. Its coastline of about 1,600 km (990 mi) is the longest in the country, most of which lies on the Kathiawar peninsula. Gujarat is the fifth-largest Indian state by area, covering some 196,024 km2 (75,685 sq mi); and the ninth-most populous state, with a population of 60.4 million. It is bordered by Rajasthan to the northeast, Dadra and Nagar Haveli and Daman and Diu to the south, Maharashtra to the southeast, Madhya Pradesh to the east, and the Arabian Sea and the Pakistani province of Sindh to the west. Gujarat's capital city is Gandhinagar, while its largest city is Ahmedabad. The Gujaratis are indigenous to the state and their language, Gujarati, is the state's official language. The state encompasses 23 sites of the ancient Indus Valley civilisation (more than any other state). The most important sites are Lothal (the world's first dry dock), Dholavira (the fifth largest site), and Gola Dhoro (where 5 uncommon seals were found). Lothal is believed to have been one of the world's first seaports. Gujarat's coastal cities, chiefly Bharuch and Khambhat, served as ports and trading centres in the Maurya and Gupta empires, and during the succession of royal Saka dynasties in the Western Satraps era. Along with Bihar, Mizoram and Nagaland, Gujarat is one of four Indian states to prohibit the sale of alcohol. The Gir Forest National Park in Gujarat is home to the only wild population of the Asiatic lion in the world.The economy of Gujarat is the fourth-largest in India, with a gross state domestic product (GSDP) of ₹19.44 trillion (US$240 billion) and has the country's 10th-highest GSDP per capita of ₹243,761 (US$3,100). Gujarat ranks 21st among Indian states and union territories in human development index. The state traditionally has low unemployment and is widely considered one of the most industrially developed states of India and a manufacturing hub.

Kolkata (English: or , Bengali: [kolˈkata] (listen); also known as Calcutta , the official name until 2001) is the capital of the Indian state of West Bengal. Located on the eastern bank of the Hooghly River, the city is approximately 80 km (50 mi) west of the border with Bangladesh. It is the primary business, commercial, and financial hub of Eastern India and the main port of communication for North-East India. According to the 2011 Indian census, Kolkata is the seventh-most populous city in India, with a population of 45 lakh (4.5 million) residents within the city limits, and a population of over 1.41 crore (14.1 million) residents in the Kolkata Metropolitan Area. It is the third-most populous metropolitan area in India. In 2021, the Kolkata metropolitan area crossed 1.5 crore (15 million) registered voters. The Port of Kolkata is India's oldest operating port and its sole major riverine port. Kolkata is regarded as the cultural capital of India. Kolkata is the second largest Bengali-speaking city after Dhaka. It has the highest number of nobel laureates among all cities in India.In the late 17th century, 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, the area was developed by the Company into an increasingly fortified trading post known as Fort William. Nawab Siraj ud-Daulah occupied Calcutta in 1756, and the East India Company retook it the following year. In 1793 the East India Company was strong enough to abolish native rule, and assumed full sovereignty of the region. Under company rule and later under the British Raj, Calcutta served as the capital of British-held territories in India until 1911. In that year, after assessing its geographical location, combined with growing nationalism in Bengal (Calcutta became the centre for the Indian independence movement), the British moved the capital to the relatively more centrally located New Delhi. Following independence in 1947, Kolkata, which was once the premier centre of Indian commerce, culture, and politics, suffered many decades of political violence and economic stagnation before it rebounded. A demographically diverse global city, the culture of Kolkata features idiosyncrasies that include distinctively close-knit neighbourhoods (paras) and freestyle conversations (adda). Kolkata is home to eastern India's film industry, known as Tollywood, and cultural institutions, such as the Academy of Fine Arts, the Victoria Memorial, the Asiatic Society, the Indian Museum, and the National Library of India. Among scientific institutions, Kolkata hosts the Agri Horticultural Society of India, the Geological Survey of India, the Botanical Survey of India, the Calcutta Mathematical Society, the Indian Science Congress Association, the Zoological Survey of India, the Institution of Engineers, the Anthropological Survey of India and the Indian Public Health Association. Four Nobel laureates and two Nobel Memorial Prize winners are associated with the city. Though home to major cricketing venues and franchises, Kolkata stands out in India for being the country's centre of association football and also having strong culture in other sports less widespread elsewhere.
