Here's the alternate version of South Asia from my
Another America timeline:
The colonization of the Indian subcontinent was more diffuse in this continent, with Dravidia (formerly Coromandel) going to the French, and Malabar and Ceylon going to the Dutch, while the British took the former Mughal lands of northern India as they did in OTL, with Hyderabad and Mysore remaining as buffer states between them, while Portugal retains Goa and Denmark retains the Andaman Islands to this day.
As a result the British portion of India doesn't develop a sense of pan-Indian national identity and more regional nationalisms arise among the Bengalis, Assamese, Sikhs, as among northwestern Muslims as in OTL, while a number of princely states such as Kashmir, Junagadh, and Manipur remain independent. Dravidia also develops a strong sense of nationalism and after independence begins a campaign to unite all the Dravidian speaking lands under its banner, invading Ceylon and occupying its Tamil inhabited northeast as well as sponsoring insurgencies among the Hindu majorities of Hyderabad and Mysore against their Muslim monarchies (and in turn becoming a proxy war with Hindustan). Kashmir faces a mirrored situation, with a Muslim majority contending against a Hindu monarchy, while Assam is also afflicted with ethnoreligious conflict as the mostly Christian ethnic minorities along its borders fight for independence from the Hindu center. Meanwhile Bengal, despite being split between Hindus and Muslims, has remained remarkably stable, united by a shared sense of ethnolinguistic identity.
South Asia today is a developing region defined by increasing urbanization and industralization and by significant gaps in wealth and development within and between countries. Hindustan remains the dominant power in terms of politics, economics, and culture, though it is effectively counter-balanced by the three point bloc of Pakistan, Bengal, and Dravidia (who, combined, make up around two-thirds of the population of Hindustan), on the few occasions when they can agree at least. There have been some efforts towards regional integration, although fear of Hindustani hegemony by the other countries and a sense of everyone else being against them on Hindustan's own part have prevented most substantial measures so far.
