Charles Frederick of Baden vs King Seonjo of Joseon

Charles Frederick became Margrave of Baden-Durlach at age 10, ruling under a regency until 1746. He inherited a small, fragmented territory and began a long reign focused on centralization and reform.

Charles Frederick implemented enlightened reforms in Baden, including abolishing serfdom (1783), promoting religious tolerance, reforming the legal system, and encouraging education. He was influenced by the ideas of the Enlightenment.

Through the Reichsdeputationshauptschluss (1803) and later treaties, Charles Frederick significantly expanded Baden's territory. Baden absorbed numerous smaller states and ecclesiastical territories, becoming a major German state.

Charles Frederick was elevated from Margrave to Grand Duke of Baden by Napoleon after the dissolution of the Holy Roman Empire. Baden joined the Confederation of the Rhine, gaining territory and status as a French ally.

Seonjo became king of Joseon at age 15 after the death of his uncle, King Myeongjong. His reign began with hopes for reform, but he soon faced the greatest crisis of the dynasty: the Japanese invasions.

Toyotomi Hideyoshi's Japanese forces invaded Korea, quickly overrunning much of the peninsula. Seonjo fled to Uiju near the Chinese border, abandoning the capital Seoul, which caused widespread panic and criticism.

As Japanese forces advanced, Seonjo fled north to Uiju, leaving the capital undefended. His flight demoralized the Korean military and led to the capture of Seoul by Japanese forces within weeks.

Seonjo requested military assistance from the Ming dynasty of China. Ming forces intervened, helping to push back Japanese troops and eventually leading to a stalemate and peace negotiations that ended the first invasion.

Japan launched a second invasion of Korea after peace talks failed. Seonjo again relied on Ming Chinese forces and Korean naval victories, including Admiral Yi Sun-sin's Battle of Myeongnyang, to repel the invaders.

King Seonjo died after a 41-year reign, leaving a kingdom devastated by war but still independent. His death led to the accession of his son, Gwanghaegun, who would pursue a more pragmatic foreign policy.
