> S. Asian history contains many varying political entities and cultures each covering varying sub-regions of the region covered today by India, Pakistan, and Bangladesh Sure. However, the India that is being referred to in the post is the period of Hindu renaissance during which a vast body of philosophical, secular, and scientific literature (including the developments referred to in the article) was produced. That cultural context is carried forward to a large extent in what is India today. Neither of the other countries mentioned carry this context today. Referring to Indian history and Indian civilization as S.Asian history/civilization is like referring to the Egyptian civilization as the North-east African Civilization, because the Kingdom of Kush also extended into Sudan.
