Cyrus the Great vs King Taejo of Goryeo

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.

Wang Geon (Taejo) overthrew the Later Goguryeo state and established the Goryeo dynasty, with its capital at Songak (Kaesong). This marked the beginning of a new era in Korean history.

Taejo married women from powerful local clans to secure their loyalty and integrate regional powers into the Goryeo state. This policy helped stabilize the new dynasty.

Taejo completed the unification of the Later Three Kingdoms (Later Goguryeo, Later Baekje, and Silla) under Goryeo rule. This ended the period of division and established a unified Korean state.

Taejo issued the Ten Injunctions, a set of political guidelines for his successors. These stressed the importance of Buddhism, diplomacy with China, and avoiding internal conflict.
