Cyrus the Great vs Harsha

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.

Harsha succeeded his father Prabhakaravardhana as ruler of Thanesar (in present-day Haryana). He was 16 years old and soon faced the challenge of avenging his brother-in-law's death and expanding his kingdom.

Harsha captured the city of Kannauj after defeating the Maukhari ruler Grahavarman's enemies. He made Kannauj his capital and established the Vardhana dynasty's control over the Gangetic plain, becoming the dominant power in northern India.

Harsha led military campaigns into Bengal and Odisha, defeating the Shashanka king of Gauda. He extended his empire eastward to the Bay of Bengal, though his control over these regions was not permanent.

Harsha attempted to expand southward but was defeated by the Chalukya king Pulakeshin II on the banks of the Narmada River. This battle halted Harsha's southern expansion and established the Narmada as the boundary between the two empires.

Harsha was a patron of Buddhism and supported the Nalanda University, a major center of Buddhist learning. He convened a grand Buddhist council at Kannauj attended by monks from across Asia, and built monasteries and stupas.

The Chinese Buddhist monk Xuanzang visited Harsha's court and spent time in the empire. Xuanzang's detailed accounts describe Harsha's administration, military, and religious tolerance, providing a key historical source for the period.
