Artemisia I of Caria was a queen of the ancient Greek city-state of Halicarnassus, which is now in Bodrum, present-day Turkey. She was also queen of the nearby islands of Kos, Nisyros and Kalymnos, within the Achaemenid satrapy of Caria, in about 480 BC. She was of Carian-Greek ethnicity by her father Lygdamis I, and half-Cretan by her mother. She fought as an ally of Xerxes I, King of Persia against the independent Greek city states during the second Persian invasion of Greece. She personally commanded her contribution of five ships at the naval battle of Artemisium and at the naval Battle of Salamis in 480 BC. She is mostly known through the writings of Herodotus, himself a native of Halicarnassus, who praises her courage and relates the respect in which she was held by Xerxes.
