Abd al-Rahman I vs Charles IV of Luxembourg

Abd al-Rahman I, a surviving Umayyad prince, fled the Abbasid massacre of his family in Syria. He traveled across North Africa, evading Abbasid agents, and eventually reached the Iberian Peninsula, where he sought refuge.

Abd al-Rahman I defeated the Abbasid governor Yusuf al-Fihri at the Battle of Alameda, near Cordoba. This victory secured his control over the city and solidified his position as the ruler of Al-Andalus.

Abd al-Rahman I proclaimed himself emir of Cordoba, establishing an independent Umayyad emirate in Al-Andalus. This marked the beginning of a separate Islamic state in the Iberian Peninsula, independent from the Abbasid Caliphate.

Abd al-Rahman I faced multiple rebellions from Arab and Berber factions in Al-Andalus. He suppressed these uprisings through military campaigns, consolidating his authority and establishing a centralized Umayyad state.

Abd al-Rahman I began the construction of the Great Mosque of Cordoba, a monumental architectural project. The mosque became a symbol of Umayyad power and a center of Islamic learning in Al-Andalus.

Charles, Margrave of Moravia and grandson of Henry VII, was elected King of Germany by a faction of electors opposed to Louis IV. His election was supported by Pope Clement VI, leading to a double kingship.

Charles IV founded the University of Prague (Charles University), the first university in Central Europe. It became a major center of learning and culture, attracting scholars from across Europe.

Charles IV was crowned Holy Roman Emperor in Rome by a papal legate. His coronation was the first by a pope in decades and marked a reconciliation between the empire and papacy.

Charles IV issued the Golden Bull, a constitutional document that regulated the election of the German king by seven prince-electors. It established a fixed electoral college and reduced papal influence, remaining in effect until 1806.
