Today, i'll tell you about the timeline of Korean history.

 Our first kingdom is Gojoseon, established by Dangun. Dangun is Hwanung and Ungnyeo's son. Ungnyeo was a bear, but she live in a cave eating garlic and mugwort for 100 days.

 And later there was the Three Kingdoms, Goguryeo, Baekje and Silla. We can see that china's history changed 35 times, but Goguryeo lasted about 700 years, so Goguryeo was a powerful country at that time. But Silla joined joined forces with Dang and unified all of the Three kingdoms into one.

 In 698, Daejoyoung, established Balhae. This country, Balhae is now very important country between Korea and China. China want our history, so China picked Balhae, and they are saying that Balhae is there history. this looks simple, but if Balhae is China's history, then Goguryeo is China's. And because Shilla unified all three kingdoms so Shilla and Baekje is China's too!

 So not only Gojoseon, and the three kingdoms are important, Balhae and Gaya and the other small countrys are important too.^^
