Caeria

Caeria (died 344/343 BC), was an Illyrian queen who reigned in the second part of the fourth century BC. 
Cynane, an Illyrian princess and daughter of Philip II of Macedon, engaged in battle with Caeria in 344/343 BC. An account cites that Cynane accompanied her father when this happened during his campaign in Illyria. Caeria was killed by Cynane in a hand to hand combat with a blow to the throat, and with great slaughter, her army was also defeated.
