Leo II was a Byzantine Emperor who ruled for a brief period in 474 AD. He was the son of Leo I, the previous emperor, and became emperor at a young age after his father's death. His reign lasted only a few months, as he was a minor and lacked the political power to govern effectively. During his short rule, Leo II faced challenges from powerful figures in the empire, including Zeno, who was his stepfather and later became emperor himself. Leo II's reign ended when he died in 474 AD, leading to Zeno's ascension to the throne.
