Ayeshteni said:I seem to recall some-where that Koryo was named after some dynasty that 'founded the modern state. (i will have to find out where I read this.) The Taehan-min'guk was from a a site about modern countries and that was the 'local' term for Korea overall though South Koreans refered to themselves as something else.

A quick check on google told us that Chosan was the dynasty ruling in 1395, and still ruling in 1871..

But some disputes seem prevalent, one (untrustworthy) site claims that it was the Japanese renaming Korea to Chosan in 1910, another (untrustworthy?) site claims that
According to Korean legend, Tan-Gun discovered Korea, which he called "Chosan", about 2 400 B.C. Three clans developed from ancient Chosan. Koreans were responsible for many advancements in Science and the Arts
Taehan-min'guk - means republic of Korea and is official name for South Korea.. although that is probably akin to saying 'United States of America' so the everyday phrase is Han'guk which is probably more akin to america.
About Han'guk:
7193 BC Han-In (Lord of Heaven), establishes a country 50,000-li north to south and 20,000-li east to west, called Han-guk. It comprises of twelve nations. This is believed to be a tribal league in the nationalist circles, the formation of the ethnic entity: DONGYI.
So Han'guk could work, but it was replaced by old Choson already in 2333 BC
This page is pretty good (not only beacuse it supports my cause

But Chosan is a typo from me, it should be Choson.
And Han'guk means 'One people' and was invented as a phrase for the nation in 1919..
