Indian subcontinent

The terms " Indian subcontinent " and "South Asia" are sometimes used interchangeably. The Indian subcontinent is largely a geological term referring to the land mass that drifted northeastwards from ancient Gondwana, colliding with the Eurasian plate nearly 55 million years ago, towards the end of Palaeocene. This geological region largely includes Bangladesh, Bhutan, India, Maldives, Nepal, Pakistan, and Sri Lanka. Historians Catherine Asher and Cynthia Talbot state that the term "Indian subcontinent" describes a natural physical landmass in South Asia that has been relatively isolated from the rest of Eurasia.

The use of the term Indian subcontinent began in the British Empire, and has been a term particularly common in its successors. South Asia as the preferred term is particularly common when scholars or officials seek to differentiate this region from East Asia. According to historians Sugata Bose and Ayesha Jalal, the Indian subcontinent has come to be known as South Asia "in more recent and neutral parlance." This "neutral" notion refers to the concerns of Pakistan and Bangladesh, particularly given the recurring conflicts between India and Pakistan, wherein the dominant placement of "India" as a prefix before the subcontinent might offend some political sentiments. However, in Pakistan, the term "South Asia" is considered too India-centric and was banned until 1989 after the death of Zia ul Haq. This region has also been labelled as "India" (in its classical and pre-modern sense) and " Greater India ".
