The '''Indian subcontinent''' is a [[physiographic region]] of [[Asia]] below the [[Himalayas]] which projects into the [[Indian Ocean]] between the [[Bay of Bengal]] to the east and the [[Arabian Sea]] to the west.

==Name==
Historically, the region surrounding and southeast of the Indus River was often simply referred to as "India" in many historical sources. Even today, historians use this term to denote the entire Indian subcontinent when discussing history up until the era of the British Raj. Over time, however, "India" evolved to refer to a distinct political entity that eventually became a nation-state (today the Republic of India).<ref name="Encyclopedia Britannica 2022 t419">{{cite web |date=20 September 2022 |title=Indian subcontinent Map, Countries, Population, & History |url=https://www.britannica.com/place/Indian-subcontinent |access-date=23 August 2023 |website=Encyclopædia Britannica}}</ref>

According to the [[Oxford English Dictionary]], the term ''[[Continent#Subcontinents|subcontinent]]'' signifies a "subdivision of a continent which has a distinct geographical, political, or cultural identity" and also a "large land mass somewhat smaller than a continent".<ref>''[http://unabridged.merriam-webster.com/ Webster's Third New International Dictionary, Unabridged]'', Merriam-Webster, 2002.

Since the [[Partition of India]], citizens of Pakistan (which became independent of British India in 1947) and Bangladesh (which became independent of Pakistan in 1971) often perceive the use of the ''Indian subcontinent'' as offensive and suspicious because of the dominant placement of India in the term.<ref name="farmerplus" /> As such it is being increasingly less used in those countries.{{refn|group=note|For example, a history book intended for Pakistani B.A. students by K.

Another subduction zone opened to the west, in the ocean basin above the Kohistan-Ladakh [[island arc]].
