Al-Nasir vs Sigismund

Al-Nasir began his reign by consolidating caliphal power in Baghdad and reducing the influence of the Seljuk sultan. He reorganized the administration and built a strong military, laying the foundation for a revived caliphate.

Al-Nasir allied with the Ghurids against the Khwarezmian Empire, which had become a major power. The conflict weakened the Khwarezmians but also drained caliphal resources, leading to a stalemate.

Al-Nasir reformed the futuwwa (chivalric) orders, incorporating them into the caliphal administration. He made himself the supreme head of the futuwwa, using it to spread caliphal influence across the Islamic world.

Al-Nasir launched a campaign against the Ismaili sect in the mountains of Iran, destroying their fortresses. This action aimed to eliminate a rival religious and political force and assert Sunni orthodoxy.

Al-Nasir sent an embassy to the Mongol ruler Genghis Khan, seeking an alliance against the Khwarezmian Empire. This diplomatic move failed to prevent the Mongol invasion of the Islamic world.

Al-Nasir died after a 45-year reign, leaving the caliphate stronger than it had been for centuries. His policies restored caliphal authority in Iraq and expanded its influence, but the Mongol threat loomed.

Sigismund convened the Council of Constance to end the Western Schism, which had three rival popes. The council deposed all three and elected Pope Martin V, ending the schism. Sigismund played a key role in securing the council's success, though he failed to prevent the execution of Jan Hus.

Despite Sigismund's promise of safe conduct to Jan Hus to attend the Council of Constance, Hus was arrested, tried for heresy, and burned at the stake. Sigismund's failure to protect Hus damaged his reputation and sparked the Hussite Wars in Bohemia, which would plague his reign.

Following the death of Wenceslaus IV, Sigismund claimed the throne of Bohemia, but the Hussites refused to accept him as king. This led to a series of military campaigns known as the Hussite Wars. Sigismund led several crusades against the Hussites but was repeatedly defeated by their innovative tactics under Jan

Sigismund was crowned Holy Roman Emperor by Pope Eugene IV in Rome, becoming the last emperor to be crowned in the city. This coronation marked the formal end of the Western Schism and solidified Sigismund's position as the leading secular ruler in Europe.

Sigismund negotiated the Compact of Basel with the moderate Hussites (Utraquists), granting them the right to receive communion under both kinds. This agreement temporarily ended the Hussite Wars and allowed Sigismund to finally be recognized as King of Bohemia, though the peace was fragile.
