Delhi in the context of "Bahauddin Tughril"

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.

The Delhi Sultanate or the Sultanate of Delhi was a late medieval empire primarily based in Delhi that stretched over large parts of the Indian subcontinent for more than three centuries. The sultanate was established in 1206 in the former Ghurid territories in India. The sultanate's history is generally divided into five periods: Mamluk (1206–1290), Khalji (1290–1320), Tughlaq (1320–1414), Sayyid (1414–1451), and Lodi (1451–1526). It covered large swaths of territory in modern-day India, Pakistan, Bangladesh, as well as some parts of southern Nepal.

The foundation of the Sultanate was established by the Ghurid conqueror Muhammad Ghori, who routed the Rajput Confederacy, led by Ajmer ruler Prithviraj Chauhan, in 1192 near Tarain in a reversal of an earlier battle. As a successor to the Ghurid dynasty, the Delhi Sultanate was originally one of several principalities ruled by the Turkic slave-generals of Muhammad Ghori, including Taj al-Din Yildiz, Qutb ud-Din Aibak, Bahauddin Tughril and Nasir ad-Din Qabacha, that had inherited and divided the Ghurid territories amongst themselves. Khalji and Tughlaq rule ushered a new wave of rapid and continual Muslim conquests deep into South India. The sultanate finally reached the peak of its geographical reach during the Tughlaq dynasty, occupying most of the Indian subcontinent under Muhammad bin Tughluq. A major political transformation occurred across North India, triggered by the Central Asian king Timur's devastating raid on Delhi in 1398, followed soon afterwards by the re-emergence of rival Hindu powers such as Vijayanagara Empire and Kingdom of Mewar asserting independence, and new Muslim sultanates such as the Bengal and Bahmani Sultanates breaking off. In 1526, Timurid ruler Babur invaded northern India and conquered the Sultanate, leading to its succession by the Mughal Empire.

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.

Malayalam (മലയാളം, Malayāḷam, [mɐlɐjaːɭɐm] ) is a Dravidian language, primarily spoken by the Malayali people, native to the Indian state of Kerala and the union territories of Lakshadweep and Puducherry (Mahé district). It is one of 22 scheduled languages, as well as one of 11 classical languages, of India. Malayalam has official language status in Kerala, Lakshadweep and Puducherry (Mahé).

Malayalam is spoken by significant numbers of people in India and is the majority language in the state of Kerala.

New Delhi is the capital of India and a part of the National Capital Territory of Delhi (NCT). New Delhi is the seat of all three branches of the Government of India, hosting the Rashtrapati Bhavan (Presidential Palace), Sansad Bhavan (Parliament House), and the Supreme Court. New Delhi is a municipality within the NCT, administered by the New Delhi Municipal Council (NDMC), which covers mostly Lutyens' Delhi and a few adjacent areas. The municipal area is part of a larger administrative district, the New Delhi district.

Although colloquially Delhi and New Delhi are used interchangeably to refer to the National Capital Territory of Delhi, both are distinct entities, with the municipality and the New Delhi district forming a relatively small part within the megacity of Delhi. The National Capital Region is an even larger entity, comprising the entire NCT along with adjoining districts in the two neighbouring states forming a continuously built-up area with it, including Ghaziabad, Noida, Greater Noida, Meerut, YEIDA City, Gurgaon, and Faridabad.

The Punjab Plain is a large alluvial plain in northwestern India and eastern Pakistan. The plain includes the Indian states of Punjab and Haryana and the union territory of Delhi, excluding the Shahdara district, and the eastern part of Pakistani Punjab. This plain is around 200–300 meters above mean sea level. The plain is the western part of the Indo-Gangetic Plain, and is bounded by the Sivalik Hills in the north, the Yamuna River in the east, the Thar Desert of Rajasthan to the south, the Ravi River to the northwest and Sutlej River to the southwest. The plain is extensively farmed for cereals and cotton.

The land formed of alluvium in between two rivers known as Doab is found here. 'Doab' is made up of two words — 'do' meaning two and 'ab' meaning water. Similarly 'Punjab', is also made up of two words — 'Punj' meaning five and 'ab' meaning water.

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.

A public university, state university, or public college is a university or college that is owned by the state or receives significant funding from a government. Whether a national university is considered public varies from one country (or region) to another, largely depending on the specific education landscape. In contrast a private university is usually owned and operated by a private corporation (not-for-profit or for profit). Both types are often regulated, but to varying degrees, by the government.
