The first Indian coins were minted around the 6th century BC by the Mahajanapadas of the Indo-Gangetic Plain.

On the east, its border with Bangladesh is largely defined by the Khasi Hills and Mizo Hills, and the watershed region of the Indo-Gangetic Plain.

The Himalayas are bordered on the northwest by the Karakoram and Hindu Kush ranges, on the north by the Tibetan Plateau, and on the south by the Indo-Gangetic Plain.

The highest concentration of large deer species in the tropics occurs in Southern Asia in Northern India's Indo-Gangetic Plain Region and Nepal's Terai Region.

Eventually weakened both by contention with the northwestern invaders and internal strife they broke up and gave rise to several nations around Deccan and central India regions even as the Gupta Empire arose in the Indo-Gangetic Plain and ushered in a " Golden Age " and rebirth of empire as decentralized local administrative model and the spread of Indian culture until collapse under the Huna invasions.

In the Deccan, the Chalukyas arose forming a formidable nation marking the migration of the centers of cultural and military power long held in the Indo-Gangetic Plain to the new nations forming in the southern regions of India.

Since the border follows the southern edge of the Dudhwa Range -- a subrange of the Siwaliks, here there is no Nepalese Outer Terai extending onto the main Indo-Gangetic Plain.

A part of the Indo-Gangetic Plain

Some geographers subdivide the Indo-Gangetic Plain into several parts: the Indus Valley Plain, the Punjab Plain, the Haryana Plain, and the middle and lower Ganges Plains.

By another definition, the Indo-Gangetic Plain is divided into two drainage basins by the Delhi Ridge ; the western part consists of the Punjab Plain and the Haryana Plain, and the eastern part consists of the Ganges – Bramaputra drainage systems.

This divide is only 300 metres above sea level, causing the perception that the Indo-Gangetic Plain appears to be continuous between the two drainage basins.

Roughly, the Indo-Gangetic Plain stretches across:

Until recent history, the open grasslands of the Indo-Gangetic Plain was inhabited by several large species of animal.

The Indo-Gangetic plains, also known as the " Great Plains ," are large floodplains of the Indus and the Ganges – Brahmaputra river systems.

Because it is not fully possible to define the boundaries of the Indo-Gangetic Plain, it is also difficult to give an exact list of which administrative areas are part of the plain.

There are also references in which the flat southern region of Nepal which stretches from east to west as part of the Indo-Gangetic Plain is referred to as Madhesh.

This Bronze Age civilization collapsed before the end of the second millennium BCE and was followed by the Iron Age Vedic Civilization, which extended over much of the Indo-Gangetic plain and which witnessed the rise of major polities known as the Mahajanapadas.

The dominant geographical features of North India are the Indo-Gangetic Plain and the Himalayas, which demarcate the region from Tibet and Central Asia.

The predominant geographical features of North India are the Indo-Gangetic plain which spans the states of Punjab, Haryana, Uttar Pradesh and Bihar.

Originating from the kingdom of Magadha in the Indo-Gangetic plains ( modern Bihar, eastern Uttar Pradesh and Bengal ) in the eastern side of the Indian subcontinent, the empire had its capital city at Pataliputra ( modern Patna ).

The Indian rhinoceros once ranged throughout the entire stretch of the Indo-Gangetic Plain but excessive hunting reduced their natural habitat drastically.

The range parallels the Vindhya Range to the north, and these two east-west ranges divide Indian Subcontinent into the Indo-Gangetic plain of northern India and the Deccan Plateau of the south.

The Vindhya Range () is a range of older rounded mountains and hills in the west-central Indian subcontinent, which geographically separates the Indian subcontinent into northern India ( the Indo-Gangetic plain ) and Southern India.

Furthermore, the majority of researchers have found significant evidence in support of Indo-European migration and even " elite dominance " of the northern half of the Indian subcontinent, usually pointing to three separate lines of evidence: the previously widespread distribution of Dravidian speakers, now confined to the south of India ; the fact that upper caste Brahmins share a close genetic affinity with West Eurasians, whereas low caste Indians tend to have more in common with aboriginals or East Asians ; and the comparatively recent introgression of West Eurasian DNA into the aboriginal population of the post-Neolithic Indo-Gangetic plain.

It included parts of central India, north of the Narmada River and it encompassed the entire Indo-Gangetic plain.

The Indo-Gangetic plain lies to the north and east of the plateau, and the basin of the Mahanadi River lies to the south.

At the height of his power his kingdom spanned the Punjab, Rajasthan, Gujarat, Bengal, Orissa and the entire Indo-Gangetic plain north of the Narmada River.

The Indo-Gangetic plain is bound on the north by the abruptly rising Himalayas, which feed its numerous rivers and are the source of the fertile alluvium deposited across the region by the two river systems.

The Indo-Gangetic belt is the world's most extensive expanse of uninterrupted alluvium formed by the deposition of silt by the numerous rivers.

This plateau is bounded by the Indo-Gangetic plain to the north, the Bundelkhand upland to the east, the Malwa Plateau to the south, and the East Rajasthan Uplands on the west.

Bhabhar ( Hindi and, bhābar ) is the region south of the Lower Himalayas and the Siwalik Hills It is the alluvial apron of sediments washed down from the Siwaliks along the northern edge of the Indo-Gangetic Plain.

Well connected with the Indo-Gangetic plain by road ( to New Delhi, Dehradun and Lucknow ) and rail ( New Delhi, DehraDun, Lucknow and Agra ), Haldwani is an important commercial hub.

The Terai is a belt of marshy grasslands, savannas, and forests located south of the outer foothills of the Himalaya, the Siwalik Hills, and north of the Indo-Gangetic Plain of the Ganges, Brahmaputra and their tributaries.

* Quaternary period-The alluvium which is found in the Indo-Gangetic plain belongs to this era.

The Ochre Coloured Pottery culture ( OCP ) is a 2nd millennium BC Bronze Age culture of the Indo-Gangetic Plain ( Ganges-Yamuna plain ).

The flat and fertile terrain has facilitated the repeated rise and expansion of various empires, including the Gupta empire, Kanauj, Magadha, the Maurya Empire, the Mughal Empire and the Sultanate of Delhi – all of which had their demographic and political centers in the Indo-Gangetic plain.

Shinde's territory around Gwalior and Bundelkhand was a region of rolling hills and fertile valleys that slopes down toward the Indo-Gangetic Plain to the north.
