The German Empire, now in gaudy hot pink/magenta! I painted my sphere nations with magenta dots over their capitals, but this hasn't come out very well thanks to photobucket's auto-resize. So...
The Glorious Empire of (Austria-)Germany, its Colonies, Dependencies, & Tributary Nations
(not shown: Greenland (Denmark), Luang Prabang (indep.), St. Thomas (Germany))
...on the conclusion of the war against Spain (Bourgois Dictatorship!) and Turkey, in which Peoples were Freed (Greece gained W. Macedonia, having taken Thessalia and E. Macedonia in previous wars; Albania became independent of OE; Kermanshah returned to Persia (prev. occupied by Turkey) and Germany gets a new gold mine (Taza)).
China has recently civilised, knocking Spain off the GP table, and Japan saw the Meiji Restoration shortly afterwards.
May I also draw your attention to: Argentina, or what remains of it. Fell to a Communist revolution in the latter part of the last century... its neighbours (chiefly Chile and Peru, but also Bolivia and Brazil) didn't like this, and so have been carving up its territories between them. Then there was another (Fascist) revolution, but this proved no more popular, and it is predicted that the nation of Argentina will be wiped from the face of all world maps on the expiration of its current truce agreements.
GPs:
1. UK (as mentioned, wp out of its last two wars: annexation of Johore and containment of France. I strongly suspect it has yet to modernise its fleets from mano'wars and frigates)
2. USA (ACW didn't last long... at all)
3. German Empire
4. France (slapped down by US after it got greedy with wargoals during the fight for A-L)
5. Russia ([02] DAYS since last Communist rebellion...)
6. China (first action on becoming westernised: war of annexation vs. Kutch(?!); result: white peace)
7. Netherlands (greedily fending off all attempts to sphere Belgium, Portugal and Brazil)
8. Mexico (peaceful nation with respectable clique of central American nations; slowly giving ground to US expansion)
