The Great Queen Seondeok is the story of a charismatic queen who gives up her love to become the ruler of Silla and her people. With historical battle scenes, a star studded cast and writer Kim Young-hyeon (Jewel in the Palace) helming the project, it is MBC's follow-up historical drama to Yi San: Wind of the Palace (2008) and Ju-mong: Prince of Legend (2006). During the Three Kingdoms period of Korea, Deokman (Queen Seondeok's childhood name) was born as the younger twin to King Jinpyeong. However, due to a longstanding ominous prophecy regarding twins being born in the royal family, she was smuggled out and raised with no knowledge of her royal status. Years later, still oblivious to the truth of her birth, she fatefully ends up back in the Silla palace where she joins forces with Princess Cheonmyeong, her older sister, and Hwarang Kim Yushin to oppose Misil, a sly and conniving woman who holds substantial power in the court and wants the throne for herself.
