Lygdamis of Halikarnassos, grandson of Artemisia, was tyrant of Halikarnassos around the middle of the 5th century BCE. We know of him from the biographical tradition on Herodotus and from a law inscribed on stone. Both evidence that Halikarnassos experienced civil strife under his rule, with citizens subject to exile and probably confiscation. Lygdamis exercised a formally recognized authority along with the city institutions: his power was thus to a certain degree institutionalised.
