Abu Bakr vs Otto I the Great

Abu Bakr launched military campaigns against Arabian tribes that renounced Islam or refused to pay zakat after Muhammad's death. The wars, led by generals like Khalid ibn al-Walid, reestablished Muslim control over Arabia and consolidated the caliphate.

After the death of Muhammad, Abu Bakr was elected as the first caliph (successor) at Saqifah. His election unified the Muslim community, though it caused controversy among some supporters of Ali. He became the leader of the nascent Islamic state.

Abu Bakr ordered the compilation of the Quran into a single written manuscript after many memorizers died in the Ridda Wars. Zayd ibn Thabit collected verses from various sources, creating the first official codex, which later served as the basis for Uthman's standard text.

Abu Bakr died after a brief illness, having designated Umar as his successor. His caliphate lasted only two years but established the foundations of the Islamic state, including the expansion beyond Arabia and the preservation of the Quran.

Otto married Adelaide, the widowed queen of Italy, after intervening in Italian politics. This marriage gave him control over the Kingdom of Italy and strengthened his claim to imperial authority.

Otto led a German army to defeat the Magyar (Hungarian) forces at the Lechfeld near Augsburg. This victory ended Magyar raids into Western Europe and secured Otto's reputation as a defender of Christendom.

Pope John XII crowned Otto I as Holy Roman Emperor in Rome, reviving the imperial title in the West. This event established the Holy Roman Empire as a major political entity and linked German kingship with papal authority.
