So here's my submission. It's basically a combination of several of my Victoria 2 campaigns into a single world, with the map depicting its state in 1901, 20 years after the Second Napoleonic Wars and the American Reunification. Including:
-The Empire of the East Indies (the Asian rising star-aside from Japan-, a weird Anglo-Indian mix that may surpass Britain herself in the not-too-near future)
-The Taiping Heavenly Kingdom (not even the second son of God could end the Century of Humiliation)
-The Northern Qing Empire (nobody cares about the claims of Taiwan's Southern Qing, they're mere puppets of the Japanese)
-The German Confederation (more chill with the new French Republic than you would expect)
-The (re)United States of America (the Confederate exiles in Cuba will get what they deserve for destroying the first Union, once the issue of Texas and California's extensive autonommy is solved)
-The United Republic of Peru-Bolivia (disputing with the Empire of Brazil the title of "main South American power")
-The United Kingdoms of Scandinavia (pretty chill compared to other European countries, but nationalistic claims over Finland and Estonia may change that)
-The Italian Empire (the dominance of the state by the calcified southern nobility and clergy makes many among the northern burgeoisie long for the days of the Savoy, even if they were puppets of Paris)
-The Kingdom of Britanny (Britain's way of keeping a foothold on France's doorstep in case they get expansionist ambitions for the third time; will probably cause the next great European war)
-The Mali Empire (their conquest of French Senegal showed the European powers they should look elsewhere to establish their colonies)
The South African Republic (debating wether the natives deserve more rights or not; will probably cause a civil war, which the UK is ready to take advantage of)
-Nouvelle-Zélande (conquered from Britain in the 1840's, nowadays they are independent from France in all but name)
And much, much more...
