Nations (Plato Succeeds)

Besides the Kallipolic Confederation and China, there were numerous other nations in the Plato Succeeds timeline. Some eventually joined either superpower, some adopted either's ideology but stayed independent and others maintained their independence from both powers completely.

Ancient world
Some Northern European tribes adopted aspects of the Republic but were not members of the Confederation until the Roman conquests. These include the Iceni, Silurians, Arverni and Belgae. However, the Picts, Scandinavians and Irish remain untouched until the spread of Christianity.

Any nation in the Americas or Oceania.

The south of India and sub-Saharan Africa remained independent, as was Japan.

The Middle Ages
Japan- this chain of islands fiercely staves off all attempts to violate the land of cherry blossom. No new ideologies are to be introduced other than Confucianism and even that remains a minority compared to Shinto and Buddhism. Japan remains untouched even after China starts to set up colonies in North America in the 1220's. Japan even has the weather on its side- the Chinese-Mongol fleet of Kublai Khan was destroyed by a kamikaze (divine wind).

The Aztec Empire and other Mesoamerican nations until either the 1220's or 1492 based on whether encountered by the Chinese or Confederates. The North American nations around what we call California were quickly converted to Confucianism, but many stayed independent.

The Aboriginies and Maori's were left untouched until 1400, when both Confederate and Chinese fleets encountered the respective nations. Converting them was extremely difficult.

Lithuania remained independent until conquered in the 1200's by the Teutonic Order. Northern Eurasia was a frequent target for China, which conquered it all the way to Siberia.
