The Indo-Gangetic Plain also known as the Northern plains and the North Indian River Plain is a large and fertile plain encompassing most of northern and eastern India, the most populous parts of Pakistan, and virtually all of Bangladesh. The region is named after the Indus and the Ganges, the twin river systems that drain it. The Indo-gangetic plain is home to people of many religions, Hindus, Muslims and Buddhists.
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 southern edge of the plain is marked by the Vindhya- and Satpura Range, and the Chota Nagpur Plateau. On the west rises the Iranian Plateau.
The region is one of the most populated areas on Earth, being home to nearly 900 million people (or over 1/7th of the world's population).

Topography
Topographically the plain is homogeneous, with only the floodplain bluffs, changes in river channels and other related features of river erosion forming natural features.
Two narrow terrain belts, collectively known as the Terai, constitute the northern boundary of the Indo-Gangetic Plain. In the area where the foothills of the Himalayas encounter the plain, small hills known locally as ghar (meaning house in Hindi) have been formed by coarse sands and pebbles deposited by mountain streams.
Groundwater from these areas flow on the surface where the plains begin, converting large areas along the rivers into swamps. The southern boundary of the plain begins along the edge of the Great Indian Desert in the state of Rajasthan, before continuing east along the base of the hills of the Central Highlands to the Bay of Bengal. The hills vary in elevation from 300 to 1200 metres and lie on a general east-west axis.
The Central Highlands are divided into northern and southern parts. The northern part is centered on the Aravalli Range of eastern Rajasthan. In the northern part (in the state of Madhya Pradesh), the Malwa Plateau comprises the southern part of the Central Highlands and merges with the Vindhya Range to the north and south.

Extent
As a large plain, the exact extent can vary from source to source. Roughly, the Indo-Gangetic Plain stretches across:
- Kashmir in the north;
- the Punjab region of Pakistan and the Aravalli Range;
- Sindh in the west;
- the Himalayan foothills in the east; and
- the Vindhya- and Satpura Range, and the Chota Nagpur Plateau in the south.
- goes to northern portion of gujurat
The fertile Terai region is the Nepalese extension of the Plain. The rivers encompassed are the Beas, the Chambal, the Chenab, the Ganges, the Gomti, the Indus, the Ravi, the Sutlej and the Yamuna. The soil is rich in silt, making the plain one of the most intensely farmed areas of the world. Even rural areas here are densely populated.
Agriculture
Farming on the Indo-Gangetic Plain primarily consists of rice and wheat grown in rotation. Other crops include maize, sugarcane, and cotton.
The main source of rainfall is the southwest monsoon which is normally sufficient for general agriculture. The many rivers flowing out of the Himalayas provide water for major irrigation works.
Stressed water supplies
Due to a rapidly growing population (as well as other factors such as global warming which affects monsoon and Himalayan runoff), this area is considered at high risk for water shortages in the future. This area constitutes the land between the river Brahmaputra and Aravli mountain ranges, the famous river Ganges,Yamuna,Ghaggra,Chambal and Brahmaputra flow through the area.
History
The region is known for the Indus Valley Civilisation and was responsible for the birth of ancient India. 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 centres in the Indo-Gangetic plain. During the Vedic and Epic eras of Indian history, this region was referred to as "Aryavarta" (Land of the Aryans) which was bordered on the west by the Indus river and on the south by the Vindhya Mountain range. During the Islamic period, the Turkish, Afghan and Iranian rulers referred to this region as "Hindustan" (Land of the Hindus), deriving from the Persian term for the Indus River. This term was later used to refer to the whole of India but even into the modern era, the dialect of Hindi-Urdu spoken in this region is called Hindustani, a term which is also used for the local music and culture.12
Both British and independent India also had their demographic and political centres here (first in Calcutta and then Delhi).
Languages
The language of the Indo-Gangetic plain was previously Indo-Aryan.
There is in addition a great variety of regional languages, which in several cases form a dialect chain with one another.
Cities
Among the largest cities of the Indo-Gangetic plain are Ahmedabad, Ludhiana, Delhi, Kanpur, Lucknow, Patna and Kolkata in India, Dhaka in Bangladesh, Lahore, Faisalabad, Rawalpindi-Islamabad, Multan, Hyderabad and Karachi in Pakistan. In this region, it is hard to define where one megalopolis begins and one ends.
Administrative divisions
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 on the plain.
The areas that are completely part or more than half part of the plains are:
- Bangladesh (almost the whole country)
- India
- Nepal
- the Madhesh
- Pakistan
Small parts of the following administrative areas are or are not part of the plain:
