Perdiccas

Perdiccas was a Macedonian general, successor of Alexander the Great, and the regent of Alexander's empire after his death. When Alexander was dying, he entrusted his signet ring to Perdiccas. Initially the most pre-eminent of the successors, Perdiccas effectively ruled Alexander's increasingly unstable empire from Babylon for three years until his assassination, as the kings he ruled for were incapable.
