Abu Bakr vs Cyrus 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.

Cyrus led a rebellion against the Median Empire, defeating King Astyages and capturing Ecbatana. He then united the Persian and Median tribes, establishing the Achaemenid Empire, which became the largest empire the world had yet seen.

Cyrus defeated King Croesus of Lydia at the Battle of Thymbra. The Lydian capital Sardis was captured, and Croesus was taken prisoner. This conquest brought Anatolia under Persian control and secured access to the Aegean coast.

Cyrus the Great led the Persian army to capture Babylon without significant battle. The city's gates were opened, and Cyrus entered peacefully. This conquest added Mesopotamia to the Achaemenid Empire and marked the end of the Neo-Babylonian Empire.

After conquering Babylon, Cyrus issued a clay cylinder inscribed with a declaration. It described his policy of restoring temples, repatriating displaced peoples, and allowing religious freedom. The cylinder is often cited as an early charter of human rights.

Cyrus issued an edict allowing the Jewish exiles in Babylon to return to Jerusalem and rebuild the Temple. This event is recorded in the biblical Book of Ezra and is a key moment in Jewish history, ending the Babylonian captivity.
