George IV of the United Kingdom vs Yeongjo of Joseon

When George III became temporarily insane, the Prince of Wales (future George IV) sought to become regent. The crisis ended when the king recovered, but it established a precedent for parliamentary control over regency.

Following George III's final mental collapse, the Prince of Wales was formally appointed Prince Regent under the Regency Act 1811. He exercised royal powers for nine years while his father lived in seclusion.

As Prince Regent, George IV commissioned John Nash to design Regent Street, Regent's Park, and the Royal Pavilion in Brighton. His patronage defined the architectural and cultural style of the Regency period.

Upon George III's death, the Prince Regent became King George IV. His accession was marred by his attempt to divorce Queen Caroline, leading to a public scandal and the Pains and Penalties Bill of 1820.

George IV became the first British monarch to visit Ireland since the Acts of Union. The visit aimed to promote loyalty but was overshadowed by the ongoing Catholic Emancipation debate.

George IV reluctantly signed the Roman Catholic Relief Act 1829, granting Catholic Emancipation. He had opposed the measure but yielded to Prime Minister Wellington's threat of resignation.

Yeongjo implemented the Tangpyeong policy to reduce factional strife by appointing officials from all factions. He banned factional labels and promoted merit-based appointments. This stabilized the court but did not eliminate factionalism entirely.

Yeongjo introduced the Gyunyeokbeop, a uniform military tax that replaced various service obligations with a cloth tax. This reduced the burden on commoners and increased state revenue, though it faced opposition from the aristocracy.

King Yeongjo ordered his son Crown Prince Sado to be locked inside a rice chest for eight days, leading to his death by starvation. Sado had been accused of mental illness and violent behavior. This event traumatized the court and led to Jeongjo's later reforms.

Yeongjo reigned for 52 years (1724-1776), the longest of any Joseon king. His reign saw cultural flourishing, economic stability, and political reforms, but also the tragic death of his son. He died at age 81, leaving a mixed legacy.
