Aegon IV Targaryen, also known as Aegon the Unworthy, was the sixth king of the Targaryen dynasty in the fictional world of Westeros. He ruled from 172 AC to 184 AC and is often remembered for his controversial reign marked by excess and poor decisions. Aegon IV's rule saw the decline of the Targaryen influence and the beginning of internal strife within the realm. Aegon IV is infamous for his numerous mistresses and the legitimization of his bastards, which led to significant political turmoil. His actions contributed to the eventual Blackfyre Rebellions, a series of civil wars that challenged the Targaryen claim to the throne. His legacy is often viewed negatively, overshadowed by his indulgent lifestyle and the chaos that followed his reign.
