It's 1914 (Hoi4, because of course), the Brits have ingeniously invested in motor trucks and armored cars in the lead up to the European War, forming 8 new Motorized Divisions of 120,000 additional troops. Great diplomatic effort is made to assure the Ottoman Empire it will not be endangered in the aftermath of German defeat. In the words of Sir Edward Grey, "I give you the full weight of the British word of honour and diplomatic tradition, we will not attack you, and France and Russia have also signed a pledge of non-aggression against you lasting forty years, as condition for our agreeing to join this war on their side." With the Persian Gulf and Egypt secure, Britain prepares the bulk of the Indian Army for transit to England, promising self-government under the British flag, and, the hopeful securing of everlasting Imperial union between the Indian and British people at the Imperial Conference.
The British, French and Russian Navies all combine for a massive assault, knocking the German High Seas Fleet off the face of the earth, while simultaneously, an enormous convoy sets sail from Portsmouth and prepares to land the Royal, Territorial and Indian Armies in what will be the largest seaborne invasion in history, near Wilhelmshaven. Like bolts of lightning, the British motorized and cavalry divisions sweep across the German heartland, determined that they shall not halt their engines until the great encirclement on the Franco-German frontier is complete.
One week later, the German army is halved. 3 months later.., the war is over. Patriotic fervor reaches a fever pitch, and basking in the glory the British and Dominion governments resolve once and for all to secure the constitutional bond of the whole of the British Empire. The concept is sound, they know they want an Imperial government strictly limited to Imperial matters (foreign affairs, defence, trade negotiation, some elements of finance, a court in London for international arbitration), and the particulars of obligated defence contributions - though thorny - are ironed out, but one problem still eludes them. What bloody name to give it!
What name could the new Imperial Federation have that would make Indians not only feel they belong to it, but that "it" belongs to them as well, which is the only way to keep the union long-term. Here are some of the names I've thought of, and my first inclination was to go with "United Kingdom", with either the Council of Princely States having a vote in the Imperial Council/Parliament (along with the British monarch of course, and this may only come in due time), or an Indian monarch, or two making up one vote if they agree; a hindu high prince and muslim sultan, with all three major religions having a figurehead, or, perhaps most lofty of all......the heir to the throne of England marries an Indian princess. Below are the names I've been pondering, but I call on your help to figure out the best one, so feel free of course to add your own. If you think using the word "British" would work long-term, explain yourself lol, because I don't think it lasts past 1960-70 (in my timeline feudalism is gradually abolished in India, so they will be growing far wealthier than in OTL). I'll display the poll results but try not to let it sway you your instinct.
