Doab in the context of "Punjab Plain"

The Vijayanagara Empire, also known as the Karnata Kingdom, was a late medieval Hindu empire that ruled much of southern India. It was established in 1336 by the brothers Harihara I and Bukka Raya I of the Sangama dynasty, belonging to the Yadava clan of Chandravamsa lineage.

The empire rose to prominence as a culmination of attempts by the southern powers to ward off Muslim invasions by the end of the 13th century. At its peak in the early 16th century under Krishnadevaraya, it subjugated almost all of Southern India's ruling dynasties and pushed the Deccan sultanates beyond the Tungabhadra-Krishna River doab region, in addition to annexing the Gajapati Empire (Odisha) up to the Krishna River, becoming one of the most prominent states in India. The empire's territory covered most of the lands of the modern-day Indian states of Karnataka, Andhra Pradesh, Tamil Nadu, Goa, and some parts of Telangana, Maharashtra and Kerala.

Rachna Doab (Punjabi: رچنا دوآب), also spelt as Rachena Doab, can be classified as one of the main regions of Punjab, Pakistan. Punjab historically has been divided into regions based on its various rivers, since the name Punjab is based on its five main rivers. Rachna Doab is a Doab or tract of land in the Punjab region, encompassing all the area lying between the Ravi and Chenab Rivers, all the way from the Jammu Division till their confluence south of the town of Ahmadpur Sial in Punjab, Pakistan. It lies between 30° 35' and 32° 50' N. and 71° 50' and 75° 3' E. The name was given by the Mughal emperor Akbar, by combining the first syllables of the names of the two rivers. This is the most densely-populated region in Punjab, Pakistan, home to large cities such as Lahore and Gujranwala.

Sindh Sagar Doab (Punjabi: سندھ ساگر دوآب, romanized: Sind Sāgar Dōāb), sometimes shortened as Sagar Doab, is a Doab or tract of land in the Punjab region, lying between the Indus and Jhelum rivers, in present-day Pakistan. The Doab covers a huge portion of the western areas of the Punjab province and eastern Hazara Division. It is one of the five major Doabs of the Punjab and forms the northwestern portion of the region, covering the Hazara Hills, Galyat, Pothohar Plateau and Thal Desert.

Prayagraj (/ˈpreɪəˌɡrɑːdʒ, ˈpraɪə-/, Hindi: [pɾəjaːɡɾaːdʒ]; ISO: Prayāgarāja), formerly and colloquially known as Allahabad, is a metropolis in the Indian state of Uttar Pradesh. It is the administrative headquarters of the Prayagraj district, the most populous district in the state and 13th most populous district in India and the Prayagraj division. The city is the judicial capital of Uttar Pradesh with the Allahabad High Court being the highest judicial body in the state. As of 2011, Prayagraj is the seventh most populous city in the state, thirteenth in Northern India and thirty-sixth in India, with an estimated population of 1.53 million in the city. In 2011, it was ranked the world's 40th fastest-growing city. The city, in 2016, was also ranked the third most liveable urban agglomeration in the state (after Noida and Lucknow) and sixteenth in the country. Hindi is the most widely spoken language in the city.

Prayagraj lies close to Triveni Sangam, the "three-river confluence" of the Ganges, Yamuna, and the mythical Sarasvati. It plays a central role in Hindu scriptures. The city finds its earliest reference as one of the world's oldest known cities in Hindu texts and has been venerated as the holy city of Prayāga in the ancient Vedas. Prayagraj was also known as Kosambi in the late Vedic period, named by the Kuru rulers of Hastinapur, who developed it as their capital. Known as Purimtal in ancient Jain scriptures, it is also a sacred place for Jains, as their first Tirthankar, Rishabhdeva attained kevalya gyana here. This was one of the greatest cities in India from the late Vedic period until the end of the Maurya Empire, with occupation continuing until the Gupta Empire. Since then, the city has been a political, cultural and administrative centre of the Doab region.

The Jaunpur Sultanate (Persian: سلطنت جونپور) was a late medieval Indian Muslim state which ruled over much of what is now the Indian states of Uttar Pradesh and Bihar and southern Nepal between 1394 and 1494. It was founded in 1394 by Khwajah-i-Jahan Malik Sarwar, a eunuch slave and former wazir of Sultan Nasiruddin Muhammad Shah IV Tughluq, amidst the disintegration of the Delhi Sultanate's Tughlaq dynasty. Centred in Jaunpur, the Sultanate extended authority over a large part of the Ganges-Yamuna Doab. It reached its greatest height under the rule of Sultan Ibrahim Shah, who also vastly contributed to the development of Islamic education in the Sultanate. In 1494, Sultan Hussain Shah Sharqi was defeated by the forces of the Afghan ruler Bahlul Lodi, Sultan of the Lodi dynasty of the Delhi Sultanate at Benares at which point Hussain fled to Kahalgaon in modern-day Bihar where the Sultan of Bengal assigned him a pargana. Here he was allowed to mint his own coins and was promised help from Bengal in recovering his kingdom. He died in 1505.

The Treaty of Lahore of 9 March 1846 was a peace treaty marking the end of the First Anglo-Sikh War. The treaty was concluded, for the British, by the Governor-General Sir Henry Hardinge and two officers of the East India Company and, for the Sikhs, by the seven-year-old Maharaja Duleep Singh and seven members of Hazara, the territory to the south of the river Sutlej and the forts and territory in the Jalandhar Doab between the rivers Sutlej and Beas. In addition, controls were placed on the size of the Lahore army and thirty-six field guns were confiscated. The control of the rivers Sutlej and Beas and part of the Indus passed to the British, with the Provision that this was not to interfere with the passage of passenger boats owned by the Lahore Government. Also, provision was made for the separate sale of all the hilly regions between River Beas and Indus, including Kashmir, by the East India Company at a later date to Gulab Singh, the Raja of Jammu.

Copper Hoard culture describes find-complexes which mainly occur in the western Ganges–Yamuna doab in the northern part of the Indian subcontinent. They occur in hoards large and small, and are dated to the first half of the 2nd millennium BCE, although very few derive from controlled and dateable excavation contexts. The copper hoards are associated with the Ochre Coloured Pottery (OCP), which is closely associated with the Late Harappan (or Posturban) phase of the IVC. Associations with the Indo-Aryan of the second millennium BCE have also been proposed, though association with the Vedic Aryans is problematic, since the hoards are found east of the territory of the Vedic Aryans.
