Jeong Do-jeon vs Melisende of Jerusalem

Jeong Do-jeon promoted Neo-Confucianism as the state ideology, suppressing Buddhism and advocating for a merit-based bureaucracy. His writings, like 'Joseon Gyeonggukjeon,' shaped Joseon's political philosophy.

Jeong Do-jeon drafted the foundational laws and administrative structure for the new Joseon dynasty, including the 'Gyeongguk Daejeon' (National Code). This established a centralized Confucian state.

Jeong Do-jeon was killed during the First Prince's Rebellion, a power struggle among King Taejo's sons. His death removed a key architect of the dynasty and led to a shift in Joseon's political direction.

Upon the death of her father Baldwin II, Melisende was crowned Queen of Jerusalem alongside her husband Fulk V of Anjou. This joint rule was intended to secure the succession but led to conflict as Fulk sought to exclude Melisende from power.

Fulk accused Melisende of adultery with Hugh II of Le Puiset, leading to a rebellion by Hugh's supporters. The crisis was resolved through the intervention of the Patriarch, and Melisende's position was strengthened, leading to her becoming sole ruler after Fulk's death.

After Fulk's death in a hunting accident, Melisende became sole regent for her son Baldwin III. She effectively ruled the Kingdom of Jerusalem for over a decade, managing its defenses and diplomacy during a period of external threats.

Melisende commissioned the renovation and expansion of the Church of the Holy Sepulchre in Jerusalem, including the addition of a new choir and crusader-style decoration. This project enhanced the religious prestige of the kingdom and demonstrated her piety.

Baldwin III, now of age, demanded sole rule. Melisende refused, leading to a brief civil war. Baldwin besieged her in the Tower of David, forcing her to surrender. She was granted the city of Nablus as a fief but lost political control of the kingdom.
