Chandigarh in the context of "Grand Trunk Road"

Northwest India is a loosely defined region of India. In modern-day, it consists of north-western states of the Republic of India. In historical contexts, it refers to the northwestern Indian subcontinent (including modern-day Pakistan).

In contemporary definition, it generally includes the states of Haryana, Himachal Pradesh, Punjab, Rajasthan Uttarakhand, and often Uttar Pradesh, along with the union territories of Chandigarh, Jammu and Kashmir, Ladakh, and the National Capital Territory of Delhi. Gujarat, a western coastal state, is occasionally included as well. The mountainous upper portion of Northwest India consists of the Western Himalayas, while the flat lower portion consists of the middle portion of the Indo-Gangetic plains and the Thar Desert.

Modern Standard Hindi (आधुनिक मानक हिन्दी, Hunterian: Ādhunik Mānak Hindī), commonly referred to as Hindi, is an Indo-Aryan language written in the Devanagari script. It is an official language of the Government of India, and is the lingua franca of most of the country. It is also an official language in the Pacific nation of Fiji.

Hindi is an official language in ten states (Bihar, Chhattisgarh, Gujarat, Haryana, Himachal Pradesh, Jharkhand, Madhya Pradesh, Rajasthan, Uttar Pradesh, Uttarakhand), and six union territories (Andaman and Nicobar Islands, Delhi, Chandigarh, Dadra and Nagar Haveli and Daman and Diu, Ladakh and Jammu and Kashmir) and an additional official language in the state of West Bengal. Hindi is also one of the 22 scheduled languages of the Republic of India.

Punjab (/pʌnˈdʒɑːb/ pun-JAHB; Punjabi: Panjāb, pronounced [pəɲˈd͡ʒaːb] ) is a geographical, ethnolinguistic, and historical region in South Asia, located in its northwestern part, comprising areas of modern-day Pakistan and northwestern India. It is primarily inhabited by the Punjabi people. Lahore is its largest city and historic capital, with other major cities including Faisalabad, Rawalpindi, Gujranwala, Multan, Sialkot, Sargodha, and Bahawalpur in Pakistan; alongside Ludhiana, Amritsar, Chandigarh, Jalandhar, Patiala, Mohali, Bathinda, Firozpur, and Fazilka in India.

Punjab grew out of the settlements along the five rivers, which served as an important route to the Near East as early as the ancient Indus Valley civilization, dating back to 3000 BCE, followed by migrations of the Indo-Aryan peoples. Agriculture has been the chief economic feature of the Punjab and formed the foundation of Punjabi culture. The Punjab emerged as an important agricultural region, especially following the Green Revolution during the mid-1960s to the mid-1970s, and has been described as the "breadbasket of both India and Pakistan."

Punjab (/pʌnˈdʒɑːb/ pun-JAHB; Punjabi: pañjāba, pronounced [pəɲˈd͡ʒaːb] ) is a state in northwestern India. Forming part of the larger Punjab region of the Indian subcontinent, the state is bordered by the Indian states of Himachal Pradesh to the north and northeast, Haryana to the south and southeast, and Rajasthan to the southwest; by Indian-administered Jammu and Kashmir to the north and Chandigarh to the east. To the west, it shares an international border with the identically named Pakistani province of Punjab, and as such is sometimes referred to as East Punjab or Indian Punjab for disambiguation purposes. The state covers an area of 50,362 square kilometres (19,445 square miles), which is 1.53% of India's total geographical area, making it the 19th-largest Indian state by area out of 28 Indian states (20th largest, if Union Territories are considered). With over 27 million inhabitants, Punjab is the 16th-largest Indian state by population, comprising 23 districts. Punjabi, written in the Gurmukhi script, is the most widely spoken and the official language of the state. The main ethnic group are the Punjabis, with Sikhs (57.7%) and Hindus (38.5%) forming the dominant religious groups. The state capital, Chandigarh, is a union territory and also the capital of the neighboring state of Haryana. Three of the five traditional Punjab rivers — the Sutlej, Beas, and Ravi — flow through the state.

The history of Punjab has witnessed the migration and settlement of different tribes of people with different cultures and ideas, forming a civilisational melting pot. The ancient Indus Valley Civilisation flourished in the region until its decline around 1900 BCE. Punjab was enriched during the height of the Vedic period, but declined in predominance with the rise of the Mahajanapadas. The region formed the frontier of initial empires during antiquity including Alexander's and the Maurya empires. It was subsequently conquered by the Kushan Empire, Gupta Empire, and then Harsha's Empire. Punjab continued to be settled by nomadic people; including the Huna, Turkic and the Mongols. Punjab came under Muslim rule c. 1000 CE, and was part of the Delhi Sultanate and the Mughal Empire. Sikhism, based on the teachings of Sikh Gurus, emerged between the 15th and 17th centuries. Conflicts between the Mughals and the later Sikh Gurus precipitated a militarisation of the Sikhs, resulting in the formation of a confederacy after the weakening of the Mughal Empire, which competed for control with the larger Durrani Empire. This confederacy was united in 1801 by Maharaja Ranjit Singh, forming the Sikh Empire.

North India is a geographical region, loosely defined as a cultural region comprising the northern part of India (or historically, the Indian subcontinent) wherein Indo-Aryans (speaking Indo-Aryan languages) form the prominent majority population, while Tibeto-Burmans (speaking Tibeto-Burman languages) form the significant minority population. It extends from the Himalayan mountain range in the north to the Indo-Gangetic plains, the Thar Desert, till Central Highlands. It occupies nearly two-quarters of the area and population of India and includes one of the three mega cities of India: Delhi. In a more specific and administrative sense, North India can also be used to denote the northern Indo-Gangetic Plain within this broader expanse, to the Thar Desert.

Several major rivers flow through the region including the Indus, the Ganges, the Yamuna and the Narmada rivers. North India includes the states of Himachal Pradesh, Uttarakhand, Punjab and Haryana, Rajasthan, Uttar Pradesh, and union territories of Chandigarh, Delhi, Jammu and Kashmir and Ladakh. Occasionally, states of Western, Central and Eastern India are referred as "North Indian" in a broader term.

Charles-Édouard Jeanneret (6 October 1887 – 27 August 1965), known as Le Corbusier, was a Swiss-French architectural designer, painter, urban planner and writer who was one of the pioneers of what is now regarded as modern architecture. He was born in Switzerland to French-speaking Swiss parents, and acquired French nationality by naturalization in 1930. His career spanned five decades, in which he designed buildings in Europe, Japan, India, as well as North and South America. He considered that "the roots of modern architecture are to be found in Viollet-le-Duc."

Dedicated to providing better living conditions for the residents of crowded cities, Le Corbusier was influential in urban planning, and was a founding member of the Congrès International d'Architecture Moderne (CIAM). Le Corbusier prepared the master plan for the city of Chandigarh in India, and contributed specific designs for several buildings there, especially the government buildings. In 2016, seventeen projects by Le Corbusier in seven countries were inscribed in the list of UNESCO World Heritage Sites as The Architectural Work of Le Corbusier, an Outstanding Contribution to the Modern Movement.
