Cleopatra

Last active ruler of the Ptolemaic Kingdom of Egypt — who formed political and romantic alliances with Julius Caesar and Mark Antony — the most famous female ruler of antiquity, who ultimately died by suicide after Octavian's conquest.

Demonstrates political survival through alliance with the dominant power — Cleopatra's serial alignment with Rome's strongest man (first Caesar, then Antony) as a strategy for Egyptian independence shows sophisticated realpolitik by a ruler of a client state.
