Jumong

Similarities:
==> featuring Song Il Gook who shows great range for acting characters from a distant historical era
==> the male lead undergoes training in fighting and martial arts, which are of great help to him in the future as a great leader
==> Yeo Ho Min's characters are very loyal followers to Song Il Gook's characters in both dramas
==> SPOILERS: there is a woman deeply loved by the male lead but he somehow had to end up with another woman (whom he doesn't love as much as the other but she was a good wife for him and is someone he learned to care a lot)

Aside from Song Il Gook and Yeo Ho Min, other actors found in both dramas include Bae Soo Bin and Lee Jae Yong (their characters in one drama are very different from the characters in the other drama)

Jumong and King Geunchogo shared bloodlines and both are historical dramas

Both of these dramas are about the foundation of a Kingdom. Six Flying Dragons is about the transition from Goryeo to the foundation of Joseon; and Jumong is about a prince from Buyeo who forms his own Kingdom, Goguryeo.

It's the sequel to Jumong - following the journey of Jumong's grandson

Jumong might be too long for Sungkyunkwan fans, but I think its worth for new fans of Sageuk from those who watched Sungkyunkwan to try watching a historical drama that was considered one of the best in the previous decade (2000s).
Here are the similarities:
=> Jumong is one of the few dramas BEFORE Sungkyunkwan Scandal was aired that shows a "romance" between two male characters
=> The same gender relationship in Jumong is more two-sided than the one in Sungkyunkwan
=> Like Sungkyunkwan, one of the two males who might be involved in a heartwarming relationship with another man is a hairy man while the other one is a flamboyant pretty man who likes wearing bright colored clothing (the flamboyant man in Jumong being more womanly than the one in Sungkyunkwan).
=> If you are in Sungkyunkwan for strong, determined, female characters, Jumong has them too.
=> Both dramas have some episodes dedicated to martial arts competitions. Examples including archery and swordsmanship (using sword sticks)
=> Both feature an evil male character close to the age of the male leads.

After the mythic founding of a kingdom in Jumong, Korea-Khitan War shows you what it takes to keep that kingdom alive generations later.

Loyalty, sacrifice, and survival — less in legend now, more in the cold, grinding reality of empire.

If Jumong stirred your heart with the birth of a nation, The Great Battle shows you what happens when that legacy must be defended with blood and iron.

A cinematic echo of courage — smaller in scope, but no less vital.

If Rebel Thief Who Stole the People moved you with the fight of ordinary people against injustice, Jumong offers the next dream:
Not just survival — but the building of a new world.

From stolen villages to founding kingdoms, the spirit of rebellion carries forward.

If Jumong showed you the birth of a nation through loyalty and sacrifice, My Dearest shows you the other end of the road:
what remains when loyalty endures even after the world it fought for has collapsed.

Grand myths turn into human hearts — still stubborn, still loving, even in ruin.

destroying Goguryeo and remake it in this shows.
very attractive tv series for whom want to see survival of Goguryeo .

They are both about a person who founds a new land - both engaging and very good.

Both Goguryeo dramas. Goguryeo is rarely featured in kdramas if ever so I'm glad there's another one after so many years. Fans who will watch River Where the Moon Rises should check out the representative Goguryeo drama, Jumong.

Great OST. occurs during 3 kingdoms period. beautiful cast & powerful acting.
both shows emphasize about 3rd prince(in jumong) OR 4th prince (in seodongyo) who strive to become king against all odds.

Saga about great emperor of Korea.
Gwanggaeto is descendant of Jumong.
The vibe from this two drama are very similar and you can connect when Gwanggaeto talks about history of his Kingdom bcs some of them can be found in drama Jumong.

Queen Woo is set during the Goguryeo Dynasty era, Jumong is also a drama about Goguryeo dynasty. Precisely, Jumong is about the founding of Goguryeo Dynasty. Both drama is set during the era of Goguryeo Dynasty.
