The drama begins in 1374, the final year of
King Gongmin of
Goryeo. Those times were marked by abuse of power, corruption and political chaos, as government officials and scholars dream of a new dynasty and a new era.
Jeong Do-jeon was an aristocrat and politician who assisted Yi Seong-gye (later
King Taejo) when he seized power and established a new dynasty,
Joseon. After Taejo became the first king of Joseon, he left all state affairs to Jeong, making him the most powerful and influential man who shaped the 500-year-long dynasty by laying down Joseon's ideological, institutional, and legal foundations. Deciding all policies from military affairs,
diplomacy, and down to education, he laid down Joseon's political system and
tax laws, replaced
Buddhism with
Confucianism as national religion, moved the capital from
Kaesong to Hanyang (present-day
Seoul), changed the kingdom's political system from
feudalism to highly centralized
bureaucracy, and wrote a code of laws that eventually became
Joseon's constitution. He even decided the names of each palace, eight provinces, and districts in the capital. He also worked to free many
slaves and
reformed land policy. Jeong died just six years after the foundation of Joseon, killed in 1398 by his political archenemy Yi Bang-won, Taejo's fifth son. Yi killed his two half-brothers (including the crown prince) as well as Jeong and his supporters in a coup that came to be known as the "
First Strife of Princes", eventually becoming
King Taejong, the third king of Joseon. ==Cast==
