The League of the Macedonians and Koinon of Macedonia (Ancient Greek: Κοινὸν Μακεδόνων, romanized: Koinòn Makedónōn), was a confederationally-organized commonwealth institution regional state or koinon[1]) consisting of all Macedonian communities united around a monarch.[2] It can be paralleled from the Epirote League, but it seems that the Macedonian koinon had far less power than that of the Epirote Molossians.[2] The capital, or headquarters, of the Macedonian koinon was the city of Beroia.[3]
