Explanation by empire:
Kola: Started on the Kola Peninsula, expanded onto Scandinavia while moving into Eastern Europe. Took over northern Germany and part of England in a war with Gaul, now gone.
Carthage: Started in Carthage, came into early conflict with Gaul, which had basically become the Roman Republic plus France. With the aid of Kola, Arabia, and Turkestan, took down the coalition of Gaul and Byzantium.
Turkestan: Started on the east side of the Caspian. Boring nation until it came into war with Byzantium and took some lands, which it then promptly gave to Arabia in exchange for the Straits of Hormuz.
Arabia: Started in Arabia, boring until it came into war with Byzantium and conquered it. Turkestan gave Arabia all the lands it had conquered and got the Straits of Hormuz. Byzantium used to be Turkey, Balkans, and Mesopotamia.
Bengal: Started in India, but had Ganges revolt early on. Overall, boring nation.
Ganges: Revolted from Bengal early on and then moved into Southeast Asia. Is facing pressure from China and Bengal. Sold Singapore to Celebus for Sumatra.
China: Started in China, pretty boring nation, but is putting pressure on Bengal. Currently colonizing Japan.
Siberia: Started near that lake, and expanded through conquest. They had little of interest until they met the "People from across the Great Sea" (The Aleutians in Kamchatka.)
Celebus: Started on Celebes and were naturally sea-farers. If you look, they have Indonesia, Philippines, Hawaii, nearly every Pacific Island, northern New Zealand, and part of Australia.
Australia: Started in West Australia. Boring Nation, but Western Australia rebelled. Controls Southern New Zealand.
West Australia: Revolted from Australia. Nothing of Interest.
Zaire: Started in Zaire, boring until it almost conquered Mali with the assistance of Amazonians. Currently conquering what's left of Mali.
Madagascar: Started in Madagascar, expanded onto the mainland eventually. Will backstab Zaire eventually.
Amazonia: Started in the Amazon. They met the Mali people who had come from across the Atlantic. Then all hell broke lose. I'm talking free for all warfare in all of South and Central America. Especially the Caribbean. Peace has been reached, and the Amazonians are currently conquering the root of their problems, Mali.
Inca: Started in the Andes. Known for backstabbing every one of their allies. Has fought every South American nation.
Pantagonia: Peaceful, boring nation. They had Uruguay revolt, but they eventually got it back peacefully.
Mexico: Started in Mexico. Conquered the Union of Central Countries early on, leading to hell breaking loose. Lost Caribbean and part of Florida to Mali, unable to get it back.
Mali: Started in Mali. Got across the Atlantic, but left upon discovering hell had broken loose. Now exiled to the Caribbean by Zaire and Amazonia.
I'm too bored to do the Americas, now. Wow, I just realized I have too much spare time.
