Answer:
- Cyrus the Great, king of the Achaemenid Empire
- Cyrus came to power by first conquering the Median Empire, then the Lydian Empire
- Cyrus created an organized army including the Immortals unit, consisting of 10,000 highly trained soldiers.
Step-by-step explanation:
- Cyrus the Great, king of the Achaemenid Empire, was the monarch who ended the Babylonian captivity. In the first year of his reign, he was prompted by God to decree that the Temple in Jerusalem should be rebuilt and that such Jews as cared to might return to their land for this purpose.
- Cyrus built his empire by first conquering the Median Empire, then the Lydian Empire, and eventually the Neo-Babylonian Empire. He led an expedition into Central Asia, which resulted in major campaigns that were described as having brought "into subjection every nation without exception."
- Cyrus's career as a military leader began in earnest in 550 BCE, when he rose up against his Median overlord, King Astyages. Cyrus led other much-mythologized campaigns during his reigns, such as his conquests of Lydia and Babylonia.
