Constantine VI was the son of Leo IV and Irene Sarantapechaina - Irene of Athens - the daughter of an important Greek family (there is a Sarantapichou street in Athens today). He was just a child when he came to the throne under his mother's tutelage (born in 771, he had been crowned co-emperor in 776). He turned into a vacillating and cruel emperor after he had finally managed to oust his mother from the regency in 790. He faced a number of revolts, including one by his uncle, which he suppressed with great cruelty. Finally Irene managed to return and depose him in 797; he was blinded with such ferocity that he died shortly thereafter. This early solidus shows him and his mother as equals.
