What if there was an Eigth Continent about the size of Australia whose north-east coast is in line with where the Hawaiian Island Chain is now and whose southern most coast is right on the equator. This continent is about the size of the lower 48 states of the United States, the northern most part is at the island of Midway. All the other continents and land features are the same.
Now assuming a similar history to the OTU, when does this continent get discovered by Europeans?
Who discovers it?
Who colonizes is?
What sort of natives is this continent likely to have?
How would the existance of an eigth continent affect history post discovery?
