Cheoljong of Joseon vs Frederick William II of Prussia

Cheoljong, a distant royal relative living in poverty on Ganghwa Island, was chosen as king by the Andong Kim clan. He was ill-prepared for rule and remained a figurehead, with the clan controlling all state affairs.

Under Cheoljong, the Andong Kim clan monopolized power, filling key positions with their members. Corruption and factionalism intensified, leading to administrative paralysis. The king had no real authority and was largely ignored.

The Pungyang Jo clan, led by Queen Sinjeong, began to challenge the Andong Kim clan's dominance. This factional struggle further destabilized the court. Cheoljong remained a passive observer as the two clans vied for control.

King Cheoljong died at age 32, likely from illness. He left no heir, ending the line of King Yeongjo. His death led to the selection of Gojong as the next king, with the Pungyang Jo clan gaining power and eventually leading to the regency of Heungseon Daewongun.

Frederick William II was a noted patron of music. He was a cellist and commissioned works from Wolfgang Amadeus Mozart, including the 'Prussian Quartets', and from Ludwig van Beethoven, who dedicated his Cello Sonatas Op. 5 to him. His court in Berlin became a center for classical music.

Frederick William II led Prussia into the War of the First Coalition against Revolutionary France. The Prussian army was defeated at the Battle of Valmy in 1792, a major symbolic victory for the French Revolution. Prussia withdrew from the coalition in 1795 with the Treaty of Basel, recognizing French gains.

Frederick William II participated in the Second Partition of Poland, acquiring the cities of Danzig and Thorn and the region of South Prussia. This expanded Prussian territory significantly but also brought a large Polish population under Prussian rule, creating long-term ethnic and political tensions.

Frederick William II oversaw the completion and promulgation of the Allgemeines Landrecht (General State Laws) for the Prussian States. This comprehensive legal code, begun under Frederick the Great, codified civil, criminal, and constitutional law, unifying the legal system across Prussia's diverse territories.
