Aelia Pulcheria Becomes Regent Empress

At the young age of 13, Emperor Theodosius II ceded power to his elder sister Aelia Pulcheria, who declared herself empress (Augusta) of the Eastern Roman Empire. Pulcheria's ascent marked a significant shift in imperial authority, as she took on the regency to guide her brother, ensuring stability in a time of potential tumult within the empire. Her proclamation was significant in establishing a precedent for female rulership in a male-dominated political landscape.
