[Q]: Most of the subcontinent was conquered by the Maurya Empire during the 4th and 3rd centuries BCE. From the 3rd century BC onwards Prakrit and Pali literature in the north and the Sangam literature in southern India started to flourish. Wootz steel originated in south India in the 3rd century BC and was exported to foreign countries. Various parts of India were ruled by numerous dynasties for the next 1,500 years, among which the Gupta Empire stands out. This period, witnessing a Hindu religious and intellectual resurgence, is known as the classical or "Golden Age of India". During this period, aspects of Indian civilization, administration, culture, and religion (Hinduism and Buddhism) spread to much of Asia, while kingdoms in southern India had maritime business links with the Roman Empire from around 77 CE. Indian cultural influence spread over many parts of Southeast Asia which led to the establishment of Indianized kingdoms in Southeast Asia (Greater India).

[Q]: Regardless of the ability of the Luftwaffe to win air superiority, Adolf Hitler was frustrated that it was not happening quickly enough. With no sign of the RAF weakening, and Luftwaffe air fleets (Luftflotten) taking punishing losses, the OKL was keen for a change in strategy. To reduce losses further, a change in strategy was also favoured to take place at night, to give the bombers greater protection under cover of darkness.[b] On 4 September 1940, in a long address at the Sportspalast, Hitler declared: "And should the Royal Air Force drop two thousand, or three thousand [kilograms ...] then we will now drop [...] 300,000, 400,000, yes one million kilograms in a single night. And should they declare they will greatly increase their attacks on our cities, then we will erase their cities."
[A]: The Luftwaffe air fleets were taking what kind of losses?
