I've seen it mentioned plenty of times before, but I've never actually seen an exploration of it. Basically the British Empire never dies but kind of federates into several dominions. This leaves India as the most populous. With the biggest population, a large number of partners in free trade and rapidly industrialising, India outstrips much of the rest of the Empire and becomes the de facto centre of the British Empire. What are the consequences of this shift? Is it perceived in a similar fashion to the Byzantines? The British Empire is just entering a new phase? What are the cultural implications?
