On this day in 2333BC, the state of Gojoseon (which is the present day Korea) was founded by Dangun, Wanggeom under the Lordship of the Chinese Emperor Yao.
There has been many debates as to the authenticity of that story, particularly the identity of Wangun.
Some theories have postulated that Wangun was conciever by the union of an heavenly Prince and a bear woman.
Some have said there is no concrete evidence to authenticate his existence and personality as well.
Whichever it is, today is celebrated as National Foundation Day in North and South Korea.
