Boatwright, Gargola & Talbert 2004, p. 92: "Pyrrhus matched this model. His power base was his kingship over the Molossians, a traditional office with customary limitations. To this he added the post of hegemon, or commander, of the Epirote League, an alliance of Epirote communities to which each contributed forces and funds toward common goals."

Franke 1989, p. 459: "As king of the Molossians – he never styled himself king of the Epirotes and certainly never king of Epirus, a title found especially in the Roman tradition – Pyrrhus was at the same time the hegemon of the Epirote League which was founded around 325/20 and describes itself as the ΣΥΜΜΑΧΟΙ ΤΩΝ ΑΠΕΙΡΩΤΑΝ ('the Epirote allies') on inscriptions. The League united the three main peoples of Epirus (Map 9) – the Molossians, the Thesprotians, and the Chaonians, who were evidently the last to join; each of these in turn consisted of numerous sub-groups."
